Practice exercise

00:01

This is a practice exercise video solution

00:06

for this practice.

00:07

We'll begin with the supply data set, generative actuator form design.

00:11

This design has been created from a generative outcome and there are

00:14

a couple of areas that we want to make sure that we address

00:17

areas where the outcome started to build another pipe or

00:21

stem or began to remove it but wasn't complete.

00:24

This is possible if the outcome selected was in

00:27

an earlier iteration or if it hadn't completely converged,

00:30

but either way we want to make sure that we address some of these problems

00:34

working with free form designs can often be a challenge,

00:36

but let's go ahead and take a look by

00:38

right clicking and editing this free form organic body

00:42

to begin. We want to make sure that we take a look at this in one area at a time.

00:47

So we're going to start with this area here

00:49

making our selections and hitting delete to remove faces.

00:54

Once we've removed a few faces, let's go ahead and rotate this body around.

00:57

We're going to select and delete this face as well.

01:01

Once we've deleted those, we're going to use the tool, modify and weld vertices,

01:07

we want to begin welding vertices by selecting the first vertex we want to move.

01:12

And if you get a warning telling you that you need to upgrade the T Spline version,

01:16

just simply say OK,

01:18

fusion 3 60

01:19

T spine functionality in the forms workspace does tend to update fairly often

01:23

and older bodies sometimes need to be converted.

01:26

So we're gonna make sure that we do the conversion

01:28

and then we'll begin by connecting these vertices together,

01:32

closing up this hole.

01:35

We're gonna select OK.

01:37

And take a look at the results.

01:40

While the results might not be ideal,

01:42

there are some things that we can do to further work on this geometry.

01:46

For example, this edge here creates what's called a star point.

01:50

We can use tools like smooth to help recreate a smoother version of this.

01:54

And we can also use other tools such as solidify.

01:58

When we select solidify, we can select one area of a design.

02:02

And you can see here that by making these selections,

02:05

it tries to solidify our selection.

02:08

When it gets to that start point, it has difficulty.

02:10

So you might need to select a few additional faces.

02:14

If you select too many, you can always hit X

02:17

or you can turn off auto feature selection,

02:20

turning off auto feature selection will mean that you have

02:22

to manually select the entire area that you're interested in.

02:26

Once we're done, we'll select OK.

02:27

And allow it to smooth out that area.

02:30

If you get a result like this, oftentimes it's because of that star point.

02:34

So we're gonna use control Z and undo

02:36

when you run into a start point like this, some options might be to re

02:40

apologize

02:42

by introducing T points into the design, we can re

02:46

Toppo

02:46

this.

02:47

For example, we're going to select this edge and press delete on the keyboard.

02:51

This is going to make an

02:52

NGO

02:53

or an open face. This

02:55

NGO has multiple sides or more than four.

02:58

What this means is that we could potentially have a problem in this area

03:02

using the utility repair body.

03:04

We're going to select the body and allow it to find that red

03:07

er star point

03:08

by clicking on that. We'll allow it to try to heal and fix the geometry.

03:13

We can also use the auto repair option which can

03:15

automatically find and repair other issues in the design.

03:20

Once it's repaired, that we'll say OK.

03:23

And then we're going to go to modify and insert point and

03:26

we're gonna reconnect these two points and hit enter on the keyboard,

03:30

reconnecting those two points after the star point has

03:33

been fixed will allow us to simplify the geometry.

03:36

Doing this is going to affect further downstream and

03:39

we're gonna select unfreeze to unfreeze some additional edges.

03:42

What this has done is it's unfrozen the edges at one of our preserved regions.

03:47

Whenever this happens,

03:48

we need to be careful that the edges haven't moved outside of this solid body.

03:52

The small overlap here is what allows the boundary fill feature to

03:55

create a solid body from our preserves and this free form body.

03:60

But this result is a little bit better. We can continue to use tools like smooth

04:04

and solidify to clean it up further.

04:07

We could do the same process for any areas

04:09

of this free form design that are sticking out

04:12

using tools like edit form,

04:14

insert edge and insert point as well as utilities such as

04:17

repair body and even make uniform to help simplify the geometry.

04:21

At this point.

04:22

We're not gonna fully complete this design,

04:24

but I do urge you to continue to work on selecting and cleaning

04:28

up different areas of this design to see how good you can get it

04:31

once you're done,

04:32

make sure that you finish the form and see if it can still create a solid body.

04:36

Creating a solid body is oftentimes a challenge after you've made adjustments.

04:40

And if there are any difficulties,

04:42

make sure that you do check any unfrozen edges like

04:45

this one that they still overlap the preserved geometry.

04:48

At this point, we're gonna select the home view and save the design before moving on.
