🛠️ Introduction to Fusion 360 Direct Modeling for Autodesk Certified User Exam

In this video, the focus is on covering one of the exam objectives for the Autodesk Certified User certification related to Fusion 360. The main topic discussed is the direct modeling category, particularly focusing on two objectives: feature deletion and reviewing the model history tree in the browser. The goal of the video is to guide the viewer through these processes step-by-step.

📂 Overview of the Fusion 360 Model History Tree

The video transitions to the Fusion 360 workspace, where a pre-existing part (tube hanger) is used as an example. The model history tree is highlighted as a key tool for tracking features. The single cube icon in the history tree indicates a new component (tube hanger) creation. Sketch 1 is shown to be where two circles were created, followed by extrusion. Sketch 2 showcases the creation of the main body and its connection to the circles. The history tree is emphasized as a way to track how the part was built.

🔄 Using the Model History Tree to Track Features and Revert Changes

This section covers how the model history tree can be used to explore earlier steps in the modeling process. The speaker explains that by hovering over different sketches, you can see which part of the model was affected. The ability to edit sketches, use arrows to navigate between previous steps, and view animations that show the evolution of the part is demonstrated. Turning sketches on and off allows for better visualization of the model's progression.

🛑 Deleting Features from the Model History Tree

Here, the speaker explains the process of feature deletion. For example, if the hole in the model is no longer needed, it can be deleted by right-clicking on it and selecting 'delete,' or by pressing the delete key on the keyboard. The speaker also suggests how to add a new shape, such as a square hole, without redoing the entire model, by modifying specific features.

✅ Conclusion and Exam Preparation Tips for Autodesk Certified User Exam

Transcripts

in this video we're going to cover

another

exam objective for the autodesk

certified user certification

dealing with fusion 360. so in this

video we're going to move to the direct

modeling category

and there's only two objectives here

we're going to focus on feature deletion

and just going through and reading that

model history tree that you see

in your browser so here

i'll move to fusion

and i'll go ahead and open up a part

that i've already

have kind of showing up here so here's

our tube hanger main thing is feature

deletion so all refers down to down here

at the bottom which is our model history

tree so you can see here you can kind of

keep track of what i have and looking at

the different icons so the little single

cube icon means that i created a new

component so this one was named tube

hanger i have sketch one

and again you can always go through and

right click and go back in to edit a

sketch or anything like that but sketch

one is where i created and when i hover

my mouse over i'm able to see

on the model what was actually created

so i created two circles within this

sketch and then i extruded them so you

can see the extrude one

category that shows up there so that's

what was extruded the first time out you

can actually track to see how i built

this part

when i look at sketch number two this is

where i went through and you can see i

created the main body which has the kind

of angled face and kind of connects up

over to the circles that i created

before

i then extruded that main body

and then i created the one the body here

on the end

extruded it and then i ended up putting

a hulk a hole in there for the end so

in a lot of cases if we do not want

a particular feature

and the other thing is as well is if i

want to go back like maybe from the

start i can always use these arrows down

here either i can go all the way move to

the beginning or move to a previous step

here's the next steps and again the

sketches may not go through and show up

because the sketches are not visible so

as i go into the tube hanger component

and look at the sketches i may want to

turn these on and then now if i start

from the beginning and even if i hit the

play button

i should be able to see the sketches

the extrusions and then what things were

brought into them so now let me hit to

the end if i hit play

there you'll be able to see that

animation run and show how that it was

played i'm going to turn off the

sketches here though

collapse the menus now if we want to get

rid of a feature for example like the

hole here and maybe i want to

direct model a circle in there or put a

different shape in there that's not a

hole so i can go ahead and i can right

click on this

and i can hit delete

or i could always select a feature so if

i

bring that command back select it and

press delete on my keyboard and it will

also do the same thing

now what i could do is maybe put in a

new shape in there maybe i want a square

hole

or a square opening i should say not

really a square hole i won't worry about

dimensioning it but then maybe i want to

go ahead and then extrude that through

and then have that be in there as well

so that is one way to delete a feature

without having to redo a bunch of work

and then be able to go through and put

in a desired feature or part that you

want to have created to the component

that you're making so

this concludes how to do feature

deletion out of the model history tree

and hopefully this is good information

good review for you and to know what

exactly they're looking for on the

autodesk certified user exam if you have

questions feel free to contact me

otherwise good luck in all your

preparation for the acu exam and check
