Welcome to your next lesson on digital prototyping where we'll

00:07

explore how you can turn your spines into a mesh.

00:12

How you can use box mode to refine your sculpt

00:16

and commonly used tools to help develop your design.

00:21

First, I want to show you how we can turn our previously created blinds into a 3d T

00:25

blind mesh which will act as the basis of our model

00:31

to create a mesh. Using these blinds

00:33

go to the crate form environment

00:35

and select the lo command from the crate, drop down,

00:42

select the two profiles

00:44

and make sure uniform spacing is selected to give us evenly spaced T

00:47

blind patches,

00:50

curvature spacing would more accurately resemble the shape.

00:53

Although you will have a lot more faces, edges

00:56

and vertices to manage when refining the design.

00:59

As you can see here,

01:01

I'll use uniform spacing and select one face on

01:04

the length and four faces on the width.

01:06

As these will give us a good starting point,

01:10

go into your top V mode just to make sure

01:12

everything lines up and that the spacing looks good,

01:14

then press OK.

01:18

It's worth mentioning here that sketches and teeth blinds are not associative

01:22

meaning you can update one and it won't reflect on the other.

01:27

Now, we want to match our lofted surface to our canvas

01:30

and there are a number of workflows you can adopt to do this.

01:35

In this case,

01:36

I'm gonna show you how to alternate between the

01:37

display mode options to give you better topology.

01:42

You can go into box display mode either by selecting display mode from the drop down

01:47

or by using the shortcut command. Alton one

01:52

to revert to smooth display,

01:53

simply click on the button or press alt and three

01:59

box mode is the underlying control rig beneath the smooth

02:02

shading to get best proportions and best patch layout.

02:05

So if it looks good in box display,

02:07

smooth mode will have better topology.

02:13

Before we refine, I'll first get these edges to zero.

02:16

So we know that they will be completely horizontal.

02:35

I can also see we would benefit from inserting an edge to get a sharper corner.

02:40

I use the insert edge command

02:41

set it to the exact midpoint between your subsequent edge.

02:44

Then refine using the edit form command.

03:09

Next,

03:10

I'm going to line this with a side view of our canvas by again using the edit

03:14

form command to select a mill plate until we have a shape we are happy with.

03:29

Again, we can change between display modes to check the topology of our mesh.

03:43

Now we have our mission in place,

03:45

we can start adding more faces using the face command

03:48

and bridging the two to create a smooth transition,

03:53

I'll create a four sided face the same length as our first set

03:56

of edges on the mesh using the construction plane we created earlier.

04:28

Then I'll move it vertically so it lines with our canvas.

04:37

Now

04:37

I can box select the end edge of our mesh and use the

04:40

edit form command along with alt and drag to create an adjoining phase.

04:45

I'll repeat this until we have the same amount of edges on the corresponding phases

04:49

which will make it easier when you go to bridge the two together later.

04:55

As you can see,

04:56

I am refining this shape again to better align with our canvas by changing the

05:00

view and alternating between display modes until

05:03

we have something we are happy with.

05:08

You can see here how having as few control points as possible benefits us

05:12

when creating our base shape as you have less geometry to worry about.

05:22

In this next step,

05:23

we'll bridge the two measures together.

05:26

I'll select both sides and change the number of faces to one.

05:29

So we are working with less mesh data.

05:32

The great thing about T blinds is we can add

05:34

or crate as necessary as we continue through the process.

05:46

Press OK,

05:47

then go into box display mode again to

05:49

double check the topology and refine as necessary.

06:05

Finally, I want to mirror our body.

06:07

So I only have to worry about working on one side

06:09

knowing that the changes will be reflected on the other automatically.

06:14

First though

06:15

it makes sense to align the vertices with the plane we are going to mirror around.

06:18

So there are no gaps when you perform the command

06:22

to do this, select the flatting command,

06:25

then box select these vertices

06:33

click on the direction drop down,

06:36

set the exit plan

06:38

and the selected vertices will automatically snap to that plane.

06:47

Now, we can use the mirror command

06:52

under the symmetry drop down. You'll find a number of mirror and circular features.

06:57

We're going to select the mirror duplicate feature

06:59

as you want to mirror an existing body,

07:03

simply slit the body,

07:04

the mirror plane

07:06

and the well tolerance

07:08

press. OK. And you'll see the green mirror line.

07:12

Now when I go to edit one half the other updates automatically,

07:19

this is probably a good time to use the

07:20

make uniform command before we end this lesson,

07:24

make uniform as a command that simply relaxes a T

07:27

blind mesh helping to improve the topology

07:30

and is recommended to do so after a significant change in your design.
