Keywords

💡Autodesk Certified User Certification

This is a professional certification program by Autodesk, aimed at validating the skills and knowledge of users in various Autodesk software applications. The video is focused on preparing for the exam objectives related to Fusion 360, a specific Autodesk product. The certification is important as it verifies the proficiency of individuals in using the software, which can be beneficial for their professional development.

💡Fusion 360

Fusion 360 is a cloud-based 3D CAD, CAM, and CAE tool by Autodesk that allows for the design, modeling, and fabrication of products. It is a comprehensive platform used across industries for creating complex designs and prototypes. The video script discusses how to use Fusion 360 for creating sketches and dimensions, which are fundamental aspects of the design process in this software.

💡Sketching

Sketching in Fusion 360 refers to the initial phase of creating a 2D design before moving on to 3D modeling. It is a crucial step where the basic shapes and outlines of the design are laid out. The script mentions that the video will cover creating dimensions within sketches, which helps in defining the exact size and proportions of the design.

💡Dimensions

Dimensions in the context of Fusion 360 are the numerical values assigned to specific elements of a sketch to define their size, length, or position. The video emphasizes the importance of creating dimensions within sketches, as they are essential for accurately defining the geometry of a design. Dimensions can be linear, radial, or angular, depending on the element being measured.

💡Sketch Dimension

A sketch dimension is a specific type of dimension used within the sketch environment of Fusion 360. It helps define the exact measurements of elements in a sketch. The video script provides instructions on how to invoke the sketch dimension options, such as selecting a line to define its length or using a two-click method for more precision.

💡Two-Click Method

The two-click method is a technique mentioned in the script for selecting points to create dimensions. Instead of selecting an entire line, the user clicks on two points to define a dimension, which can be more precise and useful for certain types of dimensions, like aligning a dimension to a specific direction.

💡Aligned Dimension

An aligned dimension is a type of dimension that is parallel to one of the axes in the sketch environment. The script describes how to use the aligned dimension tool to ensure that the dimension is measured along a straight line between two points, which is useful for maintaining the alignment of design elements.

💡Diameter and Radius

Diameter and radius are terms related to the measurement of circles. Diameter is the distance across the circle through its center, while the radius is half of the diameter. The video script explains how to toggle between setting dimensions by diameter or radius in Fusion 360, which is important for accurately defining the size of circular elements.

💡Driving Dimensions

Driving dimensions are dimensions in Fusion 360 that are connected to the geometry of the sketch, meaning that if the dimension value is changed, the sketch geometry will adjust accordingly. The script differentiates driving dimensions from driven dimensions, which are static and do not affect the sketch geometry when changed.

💡Driven Dimensions

Driven dimensions are dimensions in Fusion 360 that are calculated based on the driving dimensions and do not affect the sketch geometry if changed. They are used for informational purposes and provide a visual reference to the size of elements in the sketch. The script explains how to toggle a dimension from being driven to driving.

💡Keyboard Shortcut

A keyboard shortcut is a key or combination of keys pressed on the keyboard to perform a specific action quickly. In the script, the shortcut for invoking the sketch dimension tool in Fusion 360 is mentioned as the letter 'D'. Using keyboard shortcuts can increase efficiency and speed up the design process.

Transcripts

hey everyone this is going to be another

video on covering exam objectives for

the autodesk certified user

certification

exam and with that we're going to move

down the list here underneath our

sketching category and we're going to be

looking at creating dimensions within

fusion 360. so with the within the

sketching environment so as i move to

fusion

i'm going to go ahead and in a previous

video if you watched the previous one we

sketched a few shapes here just to kind

of become familiar with creating

sketches i'm going to reuse

these sketches in order to create some

dimensions so i did go through and draw

a few and put

in the last video as we

created the sketch but this time we're

going to look at how do we invoke the

sketch dimension options this is going

to be a pretty quick video if you go up

here into your menu you have sketch

dimension or if you click on create

should be the last option

the keyboard shortcut is the letter d on

the keyboard so again multiple ways to

access the same tool as you go to use it

so again creating sketch dimensions

you always look at either one of two

ways you can select the entire line and

it'll grab the length of the line so

you'll click

and click to place again we can always

set a value so if i want to change this

to two inches i can hit enter and then

another way would be for example for the

height of this i could either grab this

line or i could click on this line

click on this one and most often i have

my students utilize the two-click method

especially as we go to doing some other

editing

as we work within some of the options so

for example you know if we wanted the

length of this line we could always grab

it or we could always grab by the by the

points as well so for a circle

clicking

and then as you right click there are

some other options so either you can set

by default by it is a diameter which is

our american national standard

institute's

kind of guideline to follow by a

diameter if we want to toggle to a

radius i can right click choose radius

and then be able to go through and

utilize that so it depends on what kind

of

option that you have that you want to

choose from

so here if i want a radius of 1.2

that will go through and set that

particular sketch dimension in

as we continue through as well with the

triangle the other reason why i like to

do kind of the two point method so like

here if i choose the point of the

uh triangle and at the bottom point here

either you can set the height

so vertically you can also do like a

horizontal so from the points there but

probably the other option that you want

to look at is if you wanted to know the

true length of this line as i follow my

mouse cursor i would want to have what

they call an aligned dimension so if i

right click you'll see they have these

options that you can actually force

fusion 360 to toggle to whether it's an

aligned dimension vertical or horizontal

so as i'm doing i'm going to click

aligned and that's making sure that when

i'm forcing it you'll notice that no

matter where i move my cursor it's only

picking up an align dimension to the two

points that i selected so then i can

click

and then i can set in for example a

value of 2.5 and that'll make sure that

that side length for the triangle is two

and a half so those are the good things

about fusion 360 that as you go to

sketch and create some things is that

you want to be aware and your students

need to be aware of what types of of

dimensions you have and so for example

here if you have driving dimensions or

driven you'll notice driven dimensions

are just there

for visibility so we did not let us edit

that dimension it is just there for

informational purposes so we can always

right click on that and toggle this over

to a driving dimension which if i double

click on it after it's placed

i can make a change to it hit enter and

it'll go through and start scaling up or

changing aspects of the geometry that

i've drawn in

the sketch environment

so this kind of functionality is very

important to get familiar with because

everything that we create has to have

dimensions tied to it in order for it to

be accurately created

hopefully this has been a good review of

dimension tool and maybe hopefully you

learned a few new things along the way

if you haven't

if you haven't used this

a whole lot or just becoming more

familiar with fusion

but

hopefully it's been informational

toward your journey on becoming

successful in completing that autodesk

certified user exam

and if you ever have any questions or

anything please email me and i will see

you in the next video where we will

spotlight another fusion 360 of exam
