Transcripts

hey everyone this is another video to

spotlight one of the autodesk certified

user exam objectives for fusion 360. and

in this video we're going to take a look

at direct modeling specifically dealing

with the press and pull

tool and so as we go into fusion we're

going to see what this kind of does for

us so as we look we have a tube hanger

here that i've created and we can see

all of the

sketches and features that were

logged into the model history cheaters

to see how this part was created

under the modify panel you'll also find

or it most of the time it should be the

first option here is called press pull

and so when i use this tool it just says

to have an automatic selection so here's

one thing that i can do

is if i select the hole here on the side

i can either go through and in here it

has offset type automatic where it says

modify existing feature or new offset so

if we choose auto if we have it set to

automatic like it is by default it's

going to pick it up which actually if

you check down in your history tree

there's a three lines kind of diagonal

lines or hash marks there that are right

above the whole command so it knows that

we're kind of making a little change to

the offset

of the whole command so instead of maybe

a one inch diameter hole

maybe i want to back this down to maybe

0.5

then i can say okay

so there it's an easy modification and

if i go into my whole command by right

clicking on the feature down here on the

history tree and saying to edit the

feature

you're going to notice the setting

automatically updated as well it's set

to 0.5 so i'm going to hit cancel and if

i want to set this back

i can use the same press pull command

select the hole and then put put this

back out to one inch

and then say okay and now we have

our whole back so

a lot of times in the fusion 360 exam

they will go through and they'll have

you modify like hole sizes or

they'll have you choose even a face on

something and if they want you to

thicken or extend you can see how it's

kind of changing that particular

geometry there they will go through and

have you offset

this

by maybe a certain distance like here

maybe we want it to be two inches

or something like that and that would be

something that we can go through

and do as well now in this case this is

an offset face so since where we weren't

modifying an existing feature it did add

a new icon down here in our model

history tree so if i want to get rid of

it i can delete it and in that way it

brings back

the the geometry one thing that they

will do in the exam is i'm going to

right click on the component and go to

properties

and they want you to check or maybe

enter in what are like maybe what is the

mass

or what is the volume of the part and so

here i can see the mass

is 83.37

uh three and then the volume is 18.374

inches cubed so if i go and change

for example even the size of this hole

i can go ahead and then

take a look at

my new volume

and have to see that now my volume

is gone to

24.264 so inches cubed so this is what a

lot of the cases of the acu exam do

is they will tell

the user to change or modify something

and then report what is the volume the

new volume of the part after the changes

or maybe even what is the mass of the

part once the changes are done so you're

going to see a lot of those types of

questions that will happen where they

want you to

to communicate what that would be

so

that is it for the

press

pool tool and so for

future
