Manipulate faces edges and vertices

00:02

Manipulate faces, edges and vertices.

00:07

In this video, we'll use edit form, scale a set of faces and move a group of edges.

00:14

In Fusion 360, we want to carry on with our box primitive.

00:18

With this Body 1 we want to learn a little bit more about the modify edit form tool and how we can use it to create specific geometry.

00:27

So I'm going to start by selecting edit form and take a look at the edit form dialog.

00:32

First we need to select a Tspline entity.

00:35

The entity can either be a vertex or multiple vertices, it can be an edge or multiple edges or a face or multiple faces.

00:45

By default the selection filter is set to all, which means that we can select faces, vertices or edges.

00:54

If we do a box select, you'll notice that we're selecting faces and edges.

00:59

If we change this selection filter to vertices, you'll notice the display changes and gives us just the vertex display.

01:07

If we do a box select, we're only selecting those vertices.

01:10

The same thing is true for using just edges or just faces.

01:16

In addition to having the selection filter set to all or multi, we have a transform mode and by default this is also set to multi.

01:25

If I select a face, the multi transform manipulator on screen shows us the ability to transform in a single direction, transform in a plane,

01:38

or we can use scale in a single direction, scale in two directions or on plane, and we can also rotate.

01:48

By changing the manipulator to be only translation, we will limit the number of degrees of freedom that we have.

01:55

But oftentimes this can make the selection process a little bit easier.

01:59

If we only want to rotate or we only want to scale, using these options can simplify the process.

02:06

So in this case, if I want to scale just in the Z direction or if I want to scale in the Y direction or if I want to scale in the X direction,

02:15

I can grab just those directions.

02:18

If I want to scale in both Y and Z, I can use the upper corner, if I want to scale and X and Z, I can use this upper corner,

02:26

and X and Y, this lower corner here.

02:29

Understanding the various transform modes is a critical step in creating these Tspline bodies, but there is a lot more to the edit form tool.

02:39

Next let's talk about coordinate space.

02:41

By default, we're going to be using what's called world space and that's the coordinate system based on the view cube in the upper right hand corner.

02:49

If I select a face, a moving in X, Y and Z.

02:53

There are other options that we have.

02:55

For example, view space, view space is only going to give us two axes but it's going to be aligned to, however, our model is currently viewed.

03:04

If I rotate this around, the view space changes based on the orientation of the model in relation to our viewing point.

03:13

This can be extremely helpful but in most cases it will likely stay on world space.

03:19

There are some other options such as selection space, which can be normal to the selection of the surface or multiple surfaces.

03:28

And then we also have local per entity.

03:31

Again, local per entity can be helpful, especially when we're dealing with curvature that we want to move normal to its current position.

03:38

We aren't going to go through all of the options inside of edit form.

03:42

But there is one more that I do want to mention and that's called soft modification.

03:47

Soft modification is extremely helpful when the changes that you want to make are affecting more of the model than you intended.

03:56

For example, with soft modification off in this vertex selected, you can see that it's just pulling this single vertex,

04:04

and likely it's changing the overall shape of our design.

04:07

If we turn on soft modification, we can see colorization of the edges and vertices and the red color indicates areas that are going to move more.

04:17

The white color indicates areas that are going to move less and if none of them are shaded, those are areas that will not move.

04:23

So now as I pull, you can see that it's having more of a general effect on the body rather than just pulling that single vertex.

04:32

This can be configured based on face count, based on distance or based on another option for rectangular face count,

04:40

which lets you define length and with faces.

04:43

So for example, if I only want to affect one face in a single direction, but two faces in another, I have the ability to do that.

04:52

We can also modify the transition whether it's linear between the edges, whether it's bulge or whether it's smooth.

05:00

This is more apparent on larger models with more complex curvature,

05:04

but it is important to play around with these tools to see how they can affect the transition and changes in your models.

05:11

For now, I'm going to turn soft modification back off and select OK.

05:15

I want to navigate back to a home view and make sure that I save this before moving on.
