Keywords

💡Autodesk Fusion 360

Autodesk Fusion 360 is a cloud-based 3D CAD, CAM, and CAE tool that allows for the design and modeling of products. It is a comprehensive platform used by engineers and designers to create, visualize, and simulate their ideas before they are physically produced. In the context of the video, it is the software where the editing of a sketch is being demonstrated, which is a key part of the Autodesk Certified User exam.

💡Sketching

Sketching in CAD software like Fusion 360 refers to the creation of 2D drawings that serve as the foundation for 3D models. Sketches are made up of lines, arcs, and other geometric elements that are later used to create more complex 3D shapes. The video focuses on editing a sketch, which is an important skill for the exam as it demonstrates the ability to modify and refine designs.

💡Certified User Exam

The Autodesk Certified User Exam is a test that validates one's proficiency in using Autodesk software, such as Fusion 360. It ensures that the user has the necessary skills to effectively use the software in a professional setting. The video is a tutorial aimed at preparing for this exam, specifically focusing on the objective of editing sketches within the software.

💡Model History Tree

The Model History Tree in Fusion 360 is a panel that shows the sequence of operations used to create a model. It allows users to navigate through the different stages of the model's creation. In the video, it is mentioned as a method to access and edit a sketch, emphasizing its importance in the workflow of using Fusion 360.

💡Edit Sketch

To 'edit a sketch' in Fusion 360 means to make changes to the 2D drawing that forms the basis of a 3D model. This could involve adjusting lines, adding dimensions, or modifying constraints. The video script describes this process in detail, showing how to access the sketch for editing and the types of edits that might be required for the exam.

💡Constraints

Constraints in CAD are relationships between sketch entities that define how they are connected or related. For example, a constraint might make one line parallel to another or fix the distance between two points. The video discusses how constraints might be edited or removed as part of the exam, which is crucial for achieving the desired geometry in a sketch.

💡Dimensions

Dimensions in a sketch are measurements that define the size or position of elements. They are critical for ensuring accuracy in design. The script mentions adding dimensions such as specifying a line to be a certain length, which is a common task that might be tested in the exam to assess precision and attention to detail.

💡Coincident

Coincident is a type of constraint used in CAD to align two points or entities perfectly on top of each other with no gap. The video gives an example of making a corner of a sketch coincident to the origin, which is a specific point in the coordinate system used for reference.

💡Vertical Line

A vertical line in the context of the video refers to a sketch line that is oriented perpendicular to the horizontal plane. The script describes changing a line to be vertical and applying a dimension to it, which illustrates the process of editing a sketch to meet specific geometric criteria.

💡Inspect Panel

The Inspect Panel in Fusion 360 is a tool used to analyze and measure the properties of a sketch or model. It includes features like the Measure tool, which can be used to find distances between points. The video mentions using the Inspect Panel to verify dimensions after editing a sketch, which is an important step in the design process to ensure accuracy.

💡Undo

The 'Undo' function in Fusion 360 allows users to reverse their last action, which is a common feature in many software applications. The script mentions using 'Undo' to revert changes if an edit does not turn out as intended, highlighting the importance of being able to correct mistakes during the sketch editing process.

Transcripts

hey there everyone we're going to take a

look at another autodesk fusion 360 exam

objective for the autodesk certified

user exam

and with this specifically under the

sketching category we're going to take a

look at editing a sketch and so this

shows up twice on the exam objective so

we're just going to cover it with one

video and so there can be multiple ways

you can edit a sketch

and here's just some of the most common

things probably that you'll find in this

exam

as we look for it so here in fusion 360

i've got a sketch

that i already have created so

what happens is a file may be given to

you as the exam

taker and then you're going to have to

edit this sketch so the real key is

either one of two ways you can go down

here to your model history tree

and be able to right click on the sketch

and choose edit sketch or you can right

click and expand the sketches folder

and choose edit sketch as well so if

this is set up in a component then that

could be another way but again down here

in the model history tree edit the

sketch or you can find it in the browser

so when you edit the sketch here are

some things they might do this kind of

plays along with

your

creating dimensions as well as

constraints that you may have so for

example they may have you like

coincident the corner of the sketch to

the origin and then they may have you do

some things to edit it like for example

changing this line to a vertical line

and then also applying a dimension of

let's say four inches to it and then

going through and making some of these

particular ones

constraining some of these elements so

for example they could go through and

have a certain um

you have to delete like for example

these two parallel constraints of these

two lines we don't want them to be

parallel to each other

and you might just go through and need

to kind of edit some of the things there

so that made that to be a

horizontal line if you need you can

always control z or undo

to bring that back usually if you want

to be a vertical line you can always

again anything that's not constrained

you can click and drag into place so i'm

going to make this a little closer being

a vertical line then let's apply our

vertical line there and then again maybe

we go around and place some different

dimensions

in

and they want us to go through

and play around with some of that so

here is the thing though that what they

might do

once you go and and take a look at

what exactly have i done once i've

edited the sketch so enter the inspect

panel this is a very common tool is you

can use the measure tool

to go through and find some information

so for example they may want you to find

what's the distance between this point

right here that i just clicked on at the

top of the four inch dimension and maybe

what this point is so and they'll want

you to record down what would be the the

measurement and they will show you on

the exam to what degree of precision so

they might have four or they might show

a hashtag a decimal place and then three

hashtags after that which means i would

want to input the value just exactly as

i see on my screen here 4.854

depends on what it is that you're

looking for the other thing that

couldn't be done like in this scenario

is we could also use the dimension tool

and what might have to have happened is

we want it to be in a line dimension so

that would be a distance where as

opposed to we don't want to like maybe a

horizontal or you know a vertical

dimension to come off of that what we

want is the distance how far apart if we

just lay down a ruler and measure

between these points so an aligned

dimension would give us the exact same

thing

as we go through and take a look at what

some of the other

values

so that is kind of dealing with editing

a sketch what you'll notice is that's

kind of a combination of some of the

last videos on sketch creation and also

dealing with dimensioning and

constraints so some of these exam

objectives do build on each other as you

go forward through the exam and this is

one of those cases where editing a

sketch is kind of reminiscent of you

need to know those

few objectives to be able to do

what's in another one in this exam so

hopefully this gave you a good review

and a good idea of maybe what to expect

on the exam and hopefully

with

some of this information you're going to

be able to be very successful with that

if you have any questions

please feel feel free to email me and

likewise check out another video on

another exam objective as you prepare

for that acu exam
