05:01

🌟 ODA的开放BIM技术和战略伙伴关系

ODA作为buildingSMART国际的战略合作伙伴，致力于推动开放BIM标准的创建。ODA的开放BIM技术包括全面的IFC工具包和通过MVD XML和IDS标准进行BIM数据交换的支持。在协作方面，ODA现在支持openCDE标准，这是buildingSMART的新标准，用于共同数据环境，包括问题解决和文档交换的工作流程。ODA还提供了免费的openIFC查看器，集成了快速的专业级可视化，并支持最新的IFC版本以及冲突检测、BCF问题解决等功能。ODA承诺长期致力于开放BIM，并在BIM领域取得了重大进展。

10:03

🚀 机械CAD的进步和ODA的STEP SDK

根据会员调查，超过50%的会员请求了STEP标准交换格式的解决方案，用于3D机械CAD。ODA响应这一需求，开始开发新的STEP SDK，目标是提供具有完整数据访问和创建支持、集成可视化和发布的一流解决方案。ODA的STEP SDK将支持复杂的3D几何体，并由自有的原生实体建模器提供支持，无需依赖昂贵的第三方建模器。STEP SDK将对所有ODA会员免费提供，ODA正在加入PETA's Inc，该组织代表行业维护和发展STEP标准。

15:04

🏗️ 激光扫描技术的进步与ODA的Scan to BIM

激光扫描技术近年来迅速发展，但处理由激光扫描仪生成的点云数据的能力尚未跟上。ODA创建了一个新的战略互操作性小组，专注于将点云转换为IFC和Revit格式的3D BIM模型。ODA与ODA成员集体合作，开发点云处理、复杂3D几何体B-rep建模和BIM技术方面的技术，以解决行业的关键问题。

20:05

📈 ODA的发展历程和DWG SDK的进步

ODA的发展历程中，Drawings SDK是其开发超过20年的产品，已成为CAD行业互操作性的代名词。Drawings SDK是一个通用的CAD引擎，满足从简单的数据提取器到功能齐全的CAD编辑器的开发需求。它支持DWG和DGN两种最受欢迎的CAD格式，并提供这两种格式之间的全面双向转换。Drawings SDK是一个积极开发的项目，不仅修复问题和添加小功能，还在开发重大的新功能。今年，ODA显著改进了DGN、DWG和PDF格式之间的转换，并扩展了在Drawings SDK中本地支持的3D建模操作集。

25:07

🛠️ DWG支持的增强和特殊功能

DWG支持在ODA中有着悠久的历史，以其稳定性和众所周知的功能而闻名。ODA不断提供增强和新功能。DWG支持的改进包括字段创建和改进的实体，如M领导者、填充、关联数组和多边形以及表格实体。还实现了从内容字符串创建对象的功能。ODA独特的DWG修订技术得到了增强，用于以最优方式存储绘图历史。此外，增加了对DGN元数据的支持，提供了访问DGN文件中自定义数据的途径，例如BIM数据。

30:09

📄 PDF支持的关键点和改进

PDF支持的两个关键点是出口速度和生成的PDF文件大小。ODA现在能够使用GSH，这有助于将整个导出过程分为两个阶段：向量化和显示。向量化所有元素到缓存中，然后显示被笼络的实体到PDF文件中。第一阶段可以以多线程模式处理，从而减少导出时间。复杂的DWG模型可能包含块，PDF文件中也有类似的块实体。将DWG块转换为PDF块可以加快导出速度，减小生成的PDF文件大小，并加快PDF阅读器的处理速度。

35:10

🔄 软件公司案例研究：从AutoCAD OEM到ODA

软件公司专门从事室内设计软件的开发，主要产品包括用于厨房、浴室和卧室设计的Auto Kitchen，以及用于商业厨房的Auto Deco。这些程序基于AutoCAD OEM已有23年。近年来，他们感到软件改进受到内核的限制，因此决定使用ODA以获得更大的灵活性，并使用适应自己需求的第三方解决方案来增强功能，例如具有照片级真实感的强大的渲染引擎。转向ODA后，他们能够提高产品质量，获得更快速的技术支持，并以可承受的固定费用进行业务管理。

40:12

🔌 Westcott电气系统案例研究

Westcott最近发布了新的电气系统，该系统在其核心使用了组件。他们面临的挑战包括处理来自建筑计划的DWG格式输入，扩展计划以包含电气设备，并共享结果，保存更改后的DWG并生成整个项目文档的PDF格式。在以前的解决方案中，他们自己管理了整个工作流程，这导致了数据丢失、显示不准确和PDF文档的多页文档问题。转向ODA解决方案后，他们实现了代码基础的大幅简化、性能提升以及真正的所见即所得方法。

🛠️ ODA的3D建模和机械SDK

ODA通过自有开发的facet和solid建模器提供3D建模。ODA facet建模器最初是为了支持架构SDK而开发的，但现在它越来越多地独立于架构使用。今年的主要增强与body有关，包括绘制body功能、真实颜色纹理映射坐标和body转换到OD db subd网格。ODA solid建模器是kernel SDK的一部分，几个ODA产品包括BIMrv、Civil IFC和Drawings都使用它。

🔄 机械CAD的挑战与ODA的解决方案

Graybar GmbH的CTO Robert Grabert讨论了在产品设计市场中维护旧图纸的挑战。尽管新产品设计已经从基于DWG的解决方案转移，但图纸仍然是行业关键的工作流程。ODA的机械CAD解决方案，即Iris Mechanical，扩展了DWG编辑功能，包括用于最初用AutoCAD Mechanical创建的对象的特殊功能，如部件信息、材料清单和符合标准的部件。尽管目前并非所有版本的AutoCAD Mechanical都得到支持，但Iris Mechanical在导入、导出和渲染支持版本方面工作良好，但某些模块的DXF导出和导入尚缺失。

welcome to oda summit 2021 and thank you

for joining us today my name is neil

peterson and i'm the president of open

design alliance

during the past five years the oda

platform has been quietly undergoing a

transformation we've taken a set of

individual format sdks and evolve them

into a unified platform that can solve

an increasingly sophisticated set of

interoperability problems

our offering to the industry in 2021 is

complete interoperability for cat and

bim and that's the theme for our

conference this year

our agenda today includes technical

presentations from the oda development

team real world success stories from oda

members special guests from google and

buildingsmart international and new this

year will be a couple of panel

discussions from industry experts that i

think you'll find quite interesting

at the start of the pandemic last year

we made a smooth transition to work from

home and most of us are still in that

mode i hope that we'll be able to safely

reopen our offices by the end of this

year

but in the meantime

we've maintained an aggressive

development schedule and our team has

performed well during a difficult year

membership growth in 2020 was flat which

was not unexpected

but we finished the year strong and 2021

through third quarter has been our

strongest year on record for membership

growth

the pandemic isn't over yet

but we're hiring aggressively taking on

new projects and we see a bright future

ahead for oda

narrowing in on bim

industry experts expect the bim software

market to grow by thirteen percent

annually through twenty twenty four

global infrastructure spending over the

next twenty years is expected to be more

than ninety trillion dollars

commodity prices are expected to rise

more than 10 percent this year and labor

costs are increasing

at the same time

labor productivity growth in

construction has been increasing at a

rate of only one percent per year over

the past 20 years compared to 3.6 for

manufacturing

there's a huge opportunity for companies

that can improve the efficiency of the

construction industry through

digitization we keep a close eye on

long-term trends for the cad and bim

industries

in the last two years we've seen a clear

shift in the requests coming from oda

members

companies today are asking for

integrated technologies

common workflows for data in any format

professional grade visualization support

for open and proprietary standards and

they want everything to be available on

the web

we continue to see strong demand for our

core dwg revit and ifc technologies

but more and more companies are looking

for integrated solutions to address

problems such as customizable design

review complete interoperability is our

solution to the evolving needs of the

industry

complete interoperability is a set of

integrated technologies for working with

cad and bim data

it's format sdks on steroids it includes

common frameworks for visualization

publishing and web collaboration

and we have our own solid modeler and

facet modeler for working with complex

3d geometry

it's everything you need to build

sophisticated cad and bim applications

on any platform including web a

fundamental part of oda's mission is a

commitment to open bim

oda is a strategic partner of building

smart international

and our goals as an organization are

fully aligned with bsi

we participate in a number of bsi

working groups to help advance the

creation of open bim standards

our open bim technologies include a

comprehensive ifc toolkit as well as

support for bin data exchange through

the mvd xml and ids standards

on the collaboration side we now support

the opencde standard

and our cloud platform

opencde is bsi's new standard for common

data environments

which includes workflows for issue

resolution and document exchange

finally we have open ifc viewer our free

viewer that integrates fast professional

grade visualization with support for the

latest ifc versions along with clash

detection

bcf issue resolution and more

oda offers the best and the most

complete open bim solution on the market

today and we're committed to open bim

for the long term oda has been making

great strides with bim

but we're also seeing strong demand for

advancements in mechanical cad

in a recent member survey

more than 50 percent of our members

requested a solution for stepp the

standard exchange format for 3d

mechanical cad

in response to this demand we recently

began work on a new sdk for step

our goal is to deliver a best-in-class

solution with full data access and

creation support

integrated visualization and publishing

complex 3d geometry will be supported by

our own native solid modeler so there

won't be any dependencies on expensive

third-party modelers

and since stepp is an open standard our

step sdk will be available to all oda

members at no additional cost oda is in

the process of joining peta's inc the

organization that maintains and develops

the steps standard on behalf of the

industry

step has been around since 1994.

it's been a successful standard and one

that's still growing and adapting to the

changing needs of the industry stepp is

now part of oda's strategic mission and

we're looking forward to delivering our

new step sdk by the end of 2022

laser scanning technology has been

advancing rapidly in recent years

even the latest iphone has lidar

capabilities

but you can't say the same thing about

our ability to process the point cloud

data generated by all of these really

cool laser scanners

it's not enough to import a point cloud

and use it for reference in a design

tool we need to be able to generate bim

models automatically from point cloud

data

to address this problem oda has created

a new strategic interoperability group

for scan to bim

we're working collectively with a group

of oda members to develop technology for

converting point clouds to 3d bim models

in ifc and revit formats

with expertise in point cloud processing

complex 3d geometry b-rep modeling and

bim technologies oda is well positioned

to solve this critical industry problem

we have a group of special guests here

today from major architectural design

firms who will be giving us their

insight into the challenges and

requirements for scan to bim

thank you for your attention if you'd

like to connect my email address is

president opendesign.com enjoy the rest

of the conference

[Music]

[Music]

the first block of rde summit is

dedicated to the product we've been

developing for more than 20 years

one that's made already a synonym for

interoperability in the care industry

the product is drawings sdk a universal

cad engine satisfying the development

needs for a wide range of solutions from

simple data extractors to full featured

cad editors

drawings sdk is being used today in

thousands of member applications by

millions of end users

drawings sdk

supports two the most popular cad

formats dwg and dgn along with

comprehensive two-way conversion between

these formats

it also include

complete data exchange with pdf

both for import and export drawings sdk

is an actively developed project

we not only fix issues and add minor

features but we are also working on

major new capabilities

this year we significantly improved

conversion

between dgn dwg and pdf formats

we extended the set of 3d modeling

operations natively supported in

drawings sdk without the need for any

third-party libraries

these newly implemented features include

boolean operations

on incomplete solids support for

tolerant topology and complete

sculpturing functionality

we enhanced oda's unique dwg revisions

technology

used for storing drawings history in an

optimal way

we added support for dgn metadata that

provides access to custom data in dgn

files

for example bim data and we continue

working on improvements

to various entities now we'll see an

example of how a member is using oda

drawings sdk in a real world application

[Music]

now let us move on with our dwg vgn and

pdf triad and have a deeper look at the

dwg area

dwg support has a long history a proof

stability and well-known features but we

do not stop work and go on providing

enhancements and new features on the

regular basis dwg support improvements

were done in the following areas

fields creation

and improvements for the following

entities such as m leader hatches

associative arrays and polygon and table

entities objects creation from content

strings was implemented for text m text

dimension and table entities expressions

object parameters database variables

were supported including nested fields

on the screen you can see an

illustration a set of strings that were

used as input and a set of objects that

were created using those strings fields

trees were created as a result of using

codes as arguments for setting strings

methods such as set string set content

and set dimension string

fields trees are marked on the screen

you can see it

this approach is implemented in model

dock project to create title texts

improved visualization of true type

fonts using uniscribe windows api allows

to more accurately

draw international characters that use

democratics umlauts and similar elements

on the picture you can see

arabic western hebrew and thai fonts

the differences are marked with colors

orange old version green new version

complex entities may have sophisticated

behavior

when an application user directs a point

that doesn't mean that only these point

coordinates were changed most likely

some other properties should be changed

and recalculated accordingly as an

example we can have a look at the drug

visit that controls the directions of

the aligned text

as you see the direction of the text

stays the same despite of all the

changes of the arc another example is

applied to formulas

source data may have any format or maybe

just a text string without any format

and it's very important for the new

formulas to apply the correct format

despite of the source data formats in

the table you can see the results of

this improvement dwf database is used

for dwf underlist vectorization for dwaf

imports and exports to dwf

this year we

have two improvements

dwf to the geometry markup support was

implemented and dwf 3d support was

improved

[Music]

dgn support is also a mature ode

capability this year we introduced three

major advancements support for

associative dimensions and entities

full support for dgn metadata and

partial loading support this demo

illustrates automatic recalculation for

associative dimensions and multi-line

points associated with other elements

metadata is an important part of beam

approach it is a non-geometric data

associated with the dgn element it can

contain information about the physical

parameters costs relations between

entities some operations with dgn files

do not require access to all elements

for such cases partial loading was

implemented partial loading helps to

save and memory only the position in the

file and read the data from this

position when we need access to this

particular element

[Music]

for pdf two points are of key importance

export speed

and resulting pdf file size now we're

able to use gsh and this helps us to

divide the whole export procedure into

two phases

the first one vectorization when we

vectorize all elements to this cache and

the second one displaying when we

display the caged entities to pdf file

the first phase may be processed in

multi-thread mode thus decreasing the

export time complex dwg models may

contain blocks but there are similar

block entities in pdf files if we

convert dwg blocks to pdf blocks we get

a set of advantages

they are quicker speed of export the

resulting pdf file size will be smaller

and additionally processing of such

files by pdf readers for instance adobe

pdf readers will be done quicker pdf

import area included three main

directions for improvements clipping

support text input and widgets import we

added

image clipping support to make the

imported files as close to the original

pdf as possible for text input we have

two main enhancements preferred text

support and embedded text support

preferred text support allows us to

import text as text with any font we

wish embedded font support means the

following if the embedded font is saved

in the pdf document and fits ttf

standard it can be also saved and then

used during the visualization of the

imported dwg file complex pdf documents

may contain widgets widgets input is

designed to make the resulting document

as close to the original pdf as possible

widgets in this case are imported as a

set of images geometry and text in

addition we also implemented importing

of hyperlinks from pdf and many other

enhancements publish sdk consists of

four main parts

2d pdf export 3d pdf export psc api and

publish api 2dpdf export is quite well

known 3d pdf export requires prc model

to be embedded in the document

psc api actually can create or modify or

work with psc models and publish api

allows you to create almost any type of

pdf document this document consists of

several pages and contains all basic

elements such as 3d view and 2d view

combined on one page custom ui controls

and 2d projections and sections one more

example of an interactive document

created using publish api

on the bottom you can see the buttons to

switch between the predefined views on

the side you can see the part lists to

select parts of the model and you see

that the selected parts are highlighted

sweet wrappers are already known to many

of our members we provide wrappers for

c-sharp java and python c-sharp wrappers

have the widest coverage this year we

provided wrappers for ifc sdk

[Music]

software is a company specialized in the

development of interior design software

our main products are auto kitchen for

kitchen bathroom and bedroom design

an auto deco for commercial kitchens

our programs have been based on an

autocad oem for the last 23 years in the

recent years we felt that the

improvement for our software was limited

by the kernel

if we analyzed the advantages and

disadvantages of using autocad oem

according to our experience the main

pros would be the following using an oem

autocad engine instantly transmits more

trust and is recognized worldwide by

designers

autocad is a powerful and reliable

product and it includes an acis modeler

as the geometric modeling kernel which

is very powerful and reliable

among the main disadvantages we can

highlight the following the rendering is

limited and there's little evolution

between versions of autocad giving us no

ability to improve our renders between

versions

the current render has not changed since

the version of 2016.

the video and walkthrough module is the

same as in autocad 12. this technology

is 30 years old

autocad has only got gdi impression that

doesn't show the print previous access

it will be printed

and shadows from far shade mode cannot

be activated because there are problems

with normal computers such as those with

their clients

the response time of the technical

service is very long they're high costs

based on royalty that have risen more

than 50

in the last three years we decided to

use oda to have more flexibility by

developing our tools at a deeper level

and by using third-party solutions

adapted to our needs to enhance its

functionality such as powerful rendering

engine with photorealistic water

capabilities the change to oda gives

more flexibility in the development of

water kitchen the high quality of the

technical support and speedy fixtures

also allow us to improve and develop

water kitchen thanks to monthly version

updates fixed and reported bugs and

issues in addition the updates take into

account the developers requests in

contrast with the autofill improvements

that are focused on what the rest of the

autocad community needs

finally the payment for fixed fee

facilitates business management

especially when the fee is affordable

and reasonable the main drawbacks that

we have encountered have been the

following development is slower because

there are tools that are available in

autocad but they have to be developed by

us in order to put them into oda

the lack of rendering was an

inconvenience but at the same time it

was an opportunity for us to use a

different rendering engine that was best

suited to our needs

the solid modeler is much more basic

than acis in autocad we developed the

application using the oda mfc

application as an example as a basis but

it took more than a year to get auto

kitchen oda to have the same look and

feel as an autocad

in the development we found that we

could use the dlls with minor changes

most of the blocks used in our libraries

were valid but some studies had to be

redrawn as a display well in autocad but

not in oda

we spent most of the time on the user

interface to make the program look like

the autocad based program the new

oda-based version of auto-kitchen works

the same way as the old autocad based

one here in auto kitchen we have a newly

finished kitchen to demonstrate some of

the features and processes on the

software

before we render we need to show the

walls and ceiling that we previously hit

and then place the camera where we wish

we change the far shade and adjust the

view

of what we want to make of a render of

our rendering has four quality settings

to choose from

and here we will select the file setting

which will generate a render usually

under a minute on most designs

when we click render

the program exports all of the scene

information from lights geometry and

materials and so on

the render is then generated and takes

you to a render menu where you can make

adjustments to the image with a range of

modifiers like exposure contrast and so

on

in conclusion we are happy to have made

the change now we have a better program

at an affordable fixed fee we would like

to highlight the quality and speed of

the support service compared to our

previous experience

after two years of development we've

created a new version of the program

with the same interface as the version

based on autocad

so the customers have not noticed the

change of the engine the program's

improved functionality and the ranger

engine we link with is easy to use and

generates photorealistic images 360

panoramas and videos with better quality

that put us ahead of our

competitors hello i'm ilya from westcott

recently we released our new electrical

card system that uses the components in

its core

it was a quite long and challenging way

so the question is why

why replace an already working solution

with something different

does it really worth it

well let's figure that out

speaking of electrical engineering we

should keep in mind that it doesn't

exist in a vacuum

as input usually have a plan of building

in dwg format

the main task is to extend the plan with

electrical appliances from our data

model

after that

we need to share the results saving the

change dwg back and generating the whole

project documentation in pdf format

in our previous solution we managed

all the workflow by ourselves

what does it mean for customers and

actually for us

first

we had to convert the content of

the source wg file to our internal data

model

of course our data model is not complete

enough and a lot of original data like

custom entities or dictionaries

simply vanished during this conversion

second task was to show the internal

model on the screen for editing

and again

as we were

far away from one hundred percent the

typology

compatible the result was slightly

different to what

was expected

for instance line thickness might be not

quite circulate or

text parameters and alignments was not

always correct

third challenge

was to save the multi-page documentation

in pdf

well i bet you already know what

happened

the results in pdf look differently

again

and finally saving dwg files back was a

complete disaster for customers

despite the similar look

the inner structure of dwg was different

after passing through all our workflow

with many conversion steps

for instance

a custom hatch might be simply replaced

with a set of lines and maybe texts

all of that was definitely bad for our

customers but

it was also quite hard for us

using different components for dwg

interrupts green rendering and pdf

generation

forced us to write tons of glue chords

and that's code was supposed to be able

not only work properly but also to work

around some specific components we used

so

instead of fixing one thousands

bug dedicated to interoperability

we asked ourselves

maybe we can do better

and

yes we can the general idea is to use

audio tech stack for the whole workflow

i described earlier audi drawing is used

to read incoming dwg files

not losing details

also we have a performance boost here as

a step of converting dwg into our

internal data model is eliminated

you can simply open the wg file and here

it is

showing a drawing on the screen is

performed via audi visualize

and it's not only accurate in displaying

content

it's supposed to be

but it's also fast thanks to

gpu hardware acceleration third

saving dwg's back becomes a very simple

operation provided by jordan's

technology it's fast

reliable and it that's is more important

it preserves the structure of the

original documents we got as an input

and then

expert to pdf is performed via the

publish

despite its quite simple 2d plans there

are a lot of aspects to think about

so let's figure out why do we need ptf

experts

after all we develop sophisticated

software so

why not to use it as a viewer also

there are several reasons for that

obviously our software costs money

also it's pretty function rich and

therefore well more or less heavyweight

and also it doesn't exist for all of the

platforms yet

on the contrary pdf is quite light it's

available everywhere

and it's free

so it's a really very very important and

useful exchange format

and

despite it's just an exchange format we

shouldn't keep things stupid

we should help our users to deal with

this drawing even not having access to

our software what does it mean

first of all

as we are producing multi-page project

the table of contents is a must-have

and yes we can do that

second

we have a lot of electrical symbols on

every page

using annotations in pdf file

we can show users additional information

of these symbols like they are working

with our

cut system

then

all the pages in the document are not

independent

a symbol from one page

okay might be connected to something on

a different page

therefore we provide close page

references you can click

on on a link on one page and instantly

move to a connected page so

interactivity is really useful here

and last but not least

all the pages are generated in a card

quality according to the what you see is

what you get principle

so

as a result our customers receive a

lightweight multi-platform version of

our cut just as a pdf file

so

switching to oda solution allow us to

achieve the following goals

well

significant code based simplification of

our solution of course

performance improvement of the typology

file opening and rendering and other

interactive operations

true what you see is what you get

approach

now everything a user sees on the screen

looks the same in wg or pdf

but most important they allow us to

speak the same language as the rest of

the world we can freely understand

complex dwg files containing not only

simple graphics primitives but even

architectural elements

and we can generate such complex files

by ourselves too

and

we can provide first class drawing in

pdf files to our customers who even

maybe don't have any

card system on site

oda offers 3d modeling through our own

natively developed facet and solid

modelers the oda facet modeler was

originally developed to support

architecture sdk but now it's getting

more frequently used independent from

architecture this year our main

enhancements are related to bodies the

draw body function true colors texture

mapping coordinates and body conversion

to od db subd mesh oda solid modeler is

a part of our kernel sdk several oda

products including bimrv

civil ifc and of course drawings work

with it

solid modeler works with b-rep-based 3d

objects and implements a set of modeling

operations

this year we implemented the following

new features sheet set boolean

operations boolean operations on

incomplete solids and generation of a

network surface from a set of cross

curves this should be finished by the

end of the year a network surface is a

non-planar surface created in the space

between several 2d or 3d curves

in the direction of the u and v axes

the green and red lines are 3d curves in

the u and v directions let's watch a

short video demonstrating network

surface creation

there is a group of 3d curves for

simplification they are marked with

different colors and creation of the

network surface is pretty simple

select all curves in one direction

then in a second direction tolerant

topology support is a feature that is

worth special attention

last year boolean operations for solid

entities were open to oda members in

investigation mode

members who use boolean operations

provided feedback and we found that a

lot of models have tolerant topology

support of tolerant topology affects

boolean operations and drawings sdk

if input bodies were created outside of

oda sdks we implemented a new sculpture

operation using the oda solid modeler

the sculpt operation creates a

waterproof solid from a group of

surfaces regions solids or meshes

here is a demo of how this operation can

be used

we create a circle and do a revolve

operation to make a pipe bend

then we extrude extrude another circle

to get cylinder pipes

we add a few planes to bound the created

pipes

note that we don't need to precisely set

plane bounds or cylinder heights

then we perform a sculpt operation on

the created surfaces and get a single

solid pipe

all redundant parts are automatically

removed

now we create an elliptical arc revolve

it and perform another sculpt operation

we effectively made a fillet operation

using sculpture

all redundant parts are once again

automatically removed

[Music]

in odi there are fishes that are based

on top of other features and complex

algorithms model documentation is an

example of such feature this year we

added and fixed new commands all section

modes are now supported for section and

detail we use support of materials and

colors was implemented currently we are

working on section and detail

optimization and hidden line removal

algorithm optimization and fixes now let

us illustrate view based view section

and other comments view base comment

first we create a base view we can

exclude a part of the model and as you

see the base view is updated

correspondingly next we create

orthogonal and project it is a metric

view next we create a section view aaa

switch to the model and modify it as you

see the views changed

next we'll illustrate how to change the

appearance of the views currently we

have a base a section and a detail view

let's create a projection view

next we change the parameters and create

one more projection view

as you see two projection views look

different

we can also change the text position for

section and detail view using commands

now let us have a look at a sectioning

example let us create two section views

a a and bb and a projected view for aa

section

now let's edit the view select the bb

section and modify the section in depth

then perform the same modification for

a8

as you see the corresponding projection

view changed as well

[Music]

another advanced feature of dwg support

is revision control branch merge is an

essential part when working with

revision control

the more agile this mechanism is the

more predictable and expected result we

can get

thus this year the key focus was on this

part of revision control in old version

you couldn't get the list of conflicted

objects before the merge additionally

merge procedure influenced the whole

project now it's possible to get the

list of conflicted objects before the

merge and the merge policy became more

agile to apply changes to a particular

object only the new merge implementation

provides an extended conflict resolution

policy that helps to get a wider list of

results during conflict resolution let

us have an illustration of a conflict

for od dbm text object and make a merge

decision in run time we got two branches

one change the text color the other

color and the ear text we make a merged

and get the following conflicts conflict

one the first text as color was changed

in both branches the first time we

select prefer my changes and combine the

new font style and the new text color

for the second conflict we select my

changes only and get 2021 text with no

color changes

dwg vertical extensions allow the

advantages of dwg to be leveraged for

additional areas such as architecture

civil math and mechanical

the first three are used for the

following tasks architecture design and

drafting

civil design

and working with gis data

these areas are interconnected while

mechanical stands aside oda mechanical

sdk is a tool kit for working with

industrial standard drawing elements

such as balloons part references

surface texture symbols

taper edge symbols etc

it is developed as a sig or special

interest group project

in total we support 22 entities and

seven standards

and we support objects from versions

2013 to 2021. this year we added support

for new version of the mechanical dwg

format the new version contains new

symbol standards for welding symbols

this includes

new weld services and new types of

visualization

also new internal versions of classes

are used to convert mechanical objects

to older versions

we also modified it the class hierarchy

excluding odddb database mechanical

now it is necessary to use special

functions from the oda mechanical

namespace to convert a database to

mechanical and for switching between

modes we have made a number of

improvements new methods for the bill of

materials manager

improvements to existing methods

and visualization of bill of materials

related objects

public interfaces have been extended

with many new methods and now have more

options for interfacing with mechanical

objects

my name is robert grabert i'm the cto of

graybar gmbh a founding member of the

open design alliance

graebert develops dwg based cap products

under the iris brand and has the second

largest dwg cad user base we are

uniquely positioned in the market with

our focus on providing our cad solutions

on desktop mobile and cloud with a

consistent set of apis for our

development partners

our partners are segment leaders and

ours is for example

or two draft site by social sims

on-shape drawings by ptc and corel card

by corel

in addition we partner with vendors all

over the world to deliver vertical

solutions based on iris

dwg is core to our offerings and we

leverage the open design lines toolkits

for all our products we also participate

in all special interest groups that

extend dwg support to specialized

domains servo 3d map 3d and mechanical

we decided to participate in each group

as additional toolkits allow us to

interoperate with other solutions in the

market in each vertical

in addition to dwg we also participate

in the bmrv special interest group for

the bim features in our products

for bim we're focused on rethinking

drawing production in a bim world we

consume 2d and 3d geometry from ifc and

revit models and then leverage bim

properties and the full breadth of our

cad features to provide tools for

creating automated and associative

drawings for your models

today i will focus on a different

challenge we solve with the open design

lines toolkit maintaining legacy

drawings in the product design market

new product design has migrated away

from dwg based solutions

but drawings continue to be a key

workflow in the industry

when we talk to customers there's a huge

need to maintain part information in

drawings

in our estimation there are billions of

dwg part drawings that need to be

updated for products that are still

being manufactured or in active

maintenance

this insight was the initiating idea for

creating rs mechanical

iris mechanical extends the dwg editing

capabilities of ours with special

features for the objects originally

created with autocad mechanical

this includes part information bill of

materials and standard compliant parts

and annotations

these objects are all interrelated and

contain a lot of hidden complexity

so why is data compatibility with

autocad mechanical so important

the part information in these drawings

is not static it is not sufficient to

only visualize the all balloons and

build up materials it is also important

to access and edit all properties of the

reference parts

unfortunately pure dwg support by the

drawings sdk is not enough

applications built on top of the dwg

format have persisted a lot of business

logic in so-called custom objects

this means that without full support of

the autocad mechanical objects updating

of part information is not possible

developing autocad mechanical compatible

libraries is the task of the mechanical

special interest grid

the team has been working on building

out supported for reading rendering

editing and writing of mechanical

objects

throughout the development of iris

mechanical we work with all areas of the

mechanical libraries and i can give you

an inside look on what works really well

today and what are areas that are still

in progress

import export and rendering for the

supported versions of autocad mechanical

objects is working really well

but not all versions of autocad

mechanical are supported at the moment

more support is coming

dxf export and import is currently

missing for some modules we're the first

company using the apis and public apis

are still being extended as needed

i can say that we're working in close

collaboration with the development team

and i want to thank everybody for the

effort

one of the benefits of the special

interest group model is that all sig

members benefit from our testing and bug

reporting and can leverage the libraries

today

if you interact with product design

files the library is developed by the

mechanical special interest group are

essential

please consider joining this and other

special interest groups

more members mean we collectively make

faster progress and have access to

better libraries can unlock this data

and provide better products to our

customers please reach out to me if you

want to discuss our experiences with the

special interest groups and if you're

interested in licensing our cad tools

for mobile desktop or cloud to kickstart

your development with the oda platform
