🎨 Applying Appearances and Splitting Faces in Fusion 360

In the second paragraph, the focus shifts to applying appearances to different faces of a model and the challenges that arise when trying to apply different appearances to separate faces within the same body. The instructor creates a sketch using a fit point spline to draw an interesting shape on the face of a model. The video highlights the limitation where the entire body is selected when trying to apply an appearance, rather than individual faces. To resolve this, the instructor demonstrates the 'Split Face' tool, which allows for the separation of faces within a body. This tool is crucial for applying different appearances to distinct faces of the same body. The video shows how to select the face to split and the splitting tool, which in this case is a line drawn in the sketch. The instructor also discusses the option to extend the splitting tool if necessary. After splitting the face, the video shows how to apply different colors to each face, thus overcoming the initial limitation. The tutorial wraps up by emphasizing the importance of using modification tools in conjunction with sketches and construction methods to create diverse and complex models.

hey everyone

another video spotlighting another

autodesk certified user

certification exam objective for fusion

360.

and in this video we're going to be

taking a look at advanced modeling

specifically looking at splitting and

combining bodies so this is going to be

a real quick and short video as it's a

vid these are very simple modification

tools to use when creating 3d models so

i'm going to move into fusion and i'm

just going to do something really basic

here i'm going to go ahead and we can

create a new component

i'll just go ahead and call this the

we'll call this a rectangular prism

and we're going to create a sketch i'm

on the work plane front plane here and

i'm just going to go ahead and draw a

rectangle and it doesn't even matter

really the size

we'll go

we'll go a four by five how about that

just that way we get something

constrained so finish the sketch

and i'm going to extrude this out

let's do 10 inches

so

again you can do this with a lot of

different models and practice with this

but here is one thing that we can do

with this particular

item one is if i go to modify i've got a

few options i'm going to show you one as

well how to do

splitting a face

but also splitting a body and then doing

combine

a body as well so you can even see from

the tool tips what they're used for so

as well as splitting bodies and things

like that

so here's kind of what i what i've used

in the past

i'm gonna go ahead and create an offset

work plane and i'm gonna base it off of

this front and we'll go let's put this

right in the middle at five inches

now if i want to split this because

right now in my

browser i've got one body that's been

created from the extrusion

so but maybe i want to go ahead and

split this or have a case where i need

to split it to have just two separate

bodies to be able to edit to do two

different things

so i'm gonna go ahead and go to modify

i'm gonna go to split body

and the thing that the menu is looking

for is it says to body to split so i

either i can select the body here in the

graphics area or i can go over here to

body one and you'll see it'll highlight

um and then it says what are the

splitting tools now i'm gonna go and hit

select and i want it to split right on

that work plane so which now you're

going to see i get kind of a red area

that it highlights and picks up the

where it's going to split so i'm going

to go ahead and say okay

now if i hide the construction plane and

if i look over here i've got body one so

which is the right side there and then

i've got body two which is the side

that's kind of closest to us so now i

can do some things like for example go

into physical material

and if i want one to be a ceramic

material

like a porcelain i can apply that to one

body but then as i go into let's say

just because i had a previous video

let's say i want to make this one made

of water

now those two can can have two separate

things even though they look very

similar i maybe need them to be have

separate physical properties so for

whatever reason

so

that is one thing that can kind of

happen there

now

in order to maybe bring that back

i'm gonna go to modify

we can go to combine

so maybe i want to bring them back

together so the target body i can either

choose one or the other so the target

body is usually the kind of the desired

one that you want left and then you have

the tool bodies and it automatically

changes the select so the tool body is

i'm just going to select the second one

and either i can choose to join

or cut

or intersect i'm just going to choose to

join them and so

if i needed to i could create a new

component if i wanted to create a brand

new one out of that i could check that

box

and i can also say like keep the tools

so sometimes i like to go through

and keep the tools because it keeps a

copy of each tool body and i'm going to

say okay and we're going to see what

this does

as we go forward

so now in our combination you're going

to see body 2

is the full extent body 1

is

the tool body that we selected and

that's what it means by keeping that so

if i go back into editing the com the

combination if i uncheck that and say

okay

you're gonna see now body two

is the only thing that gets left and it

all took over

the water physical material

as the option so if i can if i need to i

can always change that back to

maybe another type of

material there so

that's a real quick way of going through

and handling combine and split

those are for bodies the exam objective

does go through and specify that but i

will go ahead and show you this kind of

scenario as well is that if i create a

sketch

and if i let's say i draw a

let's use a fit point spline

and i'm just going to kind of draw this

kind of interesting shape here

on the face

and if i say finish the sketch

right now i've got two separate faces

that i could extrude

but as i go through and look at applying

like an appearance

if i look to try to paint this

you'll notice that it picks up the whole

body or i need to check to make sure i

got faces selected

and let's see if it'll pick up the

separate faces

so

and it doesn't go through it picks up

these but it won't pick up this

so that can be one of the issues so

here's what i'm going to do go to modify

i'm going to say to split the face it

operates a very similar way what's the

face to split i'm going to choose the

top face

what's the splitting tool i'm going to

choose select and i'm going to click on

which you can kind of see i'll kind of

highlight when i hover over it i'm going

to choose that line and then there's the

splitting you know kind of the splitting

tool there

so it'll go through and it'll say split

with surface or i can choose another

option split with surface works really

well do i want to extend the splitting

tool

it'll do that if i if i need to do so a

little bit more

so in this case it's not really

necessary

so i can go ahead and keep it right

right with there right on the ends so i

can go ahead and say okay

now i got two separate faces

now when i go to apply my appearance

i can look at what kind of paint color

so again i need to change them over to

faces

now i can do blue on this face

and let's say i can do yellow on this

one

and so now that allows me to create some

new options

so again this is a

an added in modification tool but that's

how to go through and do you know split

face split body as well as doing

the combine options so utilizing

sketches but also

utilizing some of the construction

methods like utilizing planes and

everything will also be useful with how

to create

varying

uh models

with a lot of these really kind of

really cool modification tools

so

this completes the video on how to

combine and split bodies

so again if you have questions or

anything feel free to contact me

however

if you don't

continue your studying through the

autodesk certified user exam materials

as well as

you know check out other videos on my
