Insert edges and points

Insert edges and points.

00:05

After completing this video, you'll be able to

00:07

understand exact versus simple insertion,

00:10

insert, an edge, insert a point, use bevel and use slide edge

00:16

in fusion. 360. We want to begin with the supply data set edges and

00:20

points dot F 3D.

00:22

This contains a single freeform body and we want to begin by going

00:26

to our utilities and taking a look at the display mode for box display

00:31

in box display.

00:32

If we view this from the right hand side,

00:34

we can see that we've got several different divisions.

00:37

As we roll around this design,

00:39

we can see that the bottom is mostly flat and we've got a fairly sharp corner here.

00:43

If we toggle back to smooth display,

00:46

which is alt and three on a windows machine or option and three on a Mac,

00:50

we can see that those flat sections in the bottom,

00:53

even though we have a sharp corner has a fairly gradual transition.

00:57

Here.

00:58

In order to get a tighter transition,

01:00

we want to explore using insert edge and the bevel tool.

01:05

We want to begin by exploring insert edge and we

01:07

want to start by double clicking one of these edges,

01:10

grabbing that entire edge loop.

01:12

We're going to go to modify and select insert edge,

01:16

insert edge will allow us to insert an edge on either side.

01:20

And in this case, I'm gonna put it on the lower side at

01:22

around minus 0.1.

01:25

We have an option for insertion mode as simple or exact and we want to start

01:30

with the simple insertion mode to make sure that we understand what this is doing.

01:34

We'll select, OK.

01:36

And notice that now our corner has a much tighter transition.

01:40

If we go to our utilities display mode and take a look at our box display mode,

01:44

we'll notice that this bottom edge where it was inserted

01:48

has stayed completely straight.

01:50

These two edges being completely co linear

01:53

is a product of the simple insertion mode

01:57

to explore our exact insertion mode. Let's go ahead and use undo insert edge.

02:02

We'll double click this edge once more.

02:05

We'll go to insert edge, placing it again at around minus 0.1.

02:10

But this time we're gonna change to an exact insertion mode,

02:14

we're gonna say OK. And notice that our edge was not inserted at 0.1

02:20

which is around 10% of the distance between this

02:23

edge and the next edge in that direction.

02:25

And the main reason for this is because when we're using the exact insertion mode,

02:30

this is going to maintain the exact shape of our design.

02:35

And it's gonna insert that edge

02:37

but it's gonna do it in a way that allows us to maintain our shape.

02:41

So in the box display under simple insertion,

02:45

it was going to place that edge at a position relative to all the other geometry

02:50

to ensure that we kept

02:52

it. Now, something interesting also happens here, you'll notice in smooth display

02:57

that the edge does appear to be at about that 10% distance

03:00

if we use undue

03:02

and we repeat this process one more time,

03:05

taking a look at insert edge

03:07

this time,

03:08

we're going to be using the simple insertion mode once again at about minus 0.1.

03:14

And we say, OK,

03:15

notice that in smooth display, we are not really at that same 10% distance.

03:21

However, in box display, it has placed it at roughly the location we told it.

03:26

So when we're thinking about inserting edges,

03:29

we're gonna go ahead and undo this and go back to our smooth display.

03:33

We always want to consider whether or not we

03:36

want to maintain the exact shape that we have

03:39

or if we want the shape to change when we create that inserted edge.

03:44

There's another thing that we also need to consider

03:46

when inserting edges is the fact that in general,

03:50

we don't want to have any flat faces next to each other or edges that are co linear

03:55

edges that are co linear or flat faces that are next to each other.

03:59

Oftentimes produce problems in the surface geometry. Once we convert our forms.

04:04

Now,

04:04

the reason for this is because these faces and

04:07

edges are controlling the tangy direction of our shapes.

04:10

The tangy direction can begin to get a little tricky when we have several faces

04:16

next to each other that are controlling the

04:18

tang agency in exactly the same direction.

04:20

So as a general rule, we want to avoid those

04:24

co linear edges or planar faces that are right next to each other.

04:30

So how would we go about this process if we

04:32

wanted to insert an edge to change the shape,

04:35

but we want to avoid some of those problems.

04:37

Well, another tool that we have is called the bevel tool.

04:40

Now, in most cases, the bevel tool will create a flat section with co linear edges.

04:45

But if we double click and select this edge go to modify and select bevel edge.

04:51

If we only use one segment insertion,

04:54

what's gonna happen is this edge that we have selected

04:57

will disappear and it'll insert edges on both sides.

05:01

We can reduce this bevel location down to 0.1

05:05

which will create a tighter transition.

05:07

The larger this number is if we go back up to say 0.7

05:11

the more gradual that transition will be. So let's explore 0.1 1st and hit enter.

05:17

Now, even though we have a smooth design and a smooth display,

05:21

we've been able to insert those two edges

05:24

relatively close together and control a tighter transition.

05:28

If we go back to our box display.

05:30

We can see that those two edges are not co

05:33

linear and the faces are not on the same plane.

05:36

This is exactly what we want to have good quality curvature in those corners.

05:41

For the remainder of this, I'm gonna go to my alt and two display

05:46

to show my control on the outside with the smooth display underneath.

05:51

Now that we understand a little bit more

05:53

about inserting edges as well as using bevel.

05:56

Let's talk about the insert point option.

05:59

Under modify, we have a tool called insert point.

06:02

Insert point will allow us to use the same simple

06:05

or exact insertion mode like we had with insert edge.

06:08

But the place that this tool differs

06:10

is that insert point will allow us to create an edge at any location.

06:15

There will be some limitations to this tool.

06:18

However, we can begin and find the midpoint of an edge, for example here

06:23

and we can come back to the midpoint of the next edge by finding that red dot

06:28

go ahead and rotate this around a little bit.

06:31

And then we can say, OK,

06:33

by inserting edges just in a small section.

06:36

And for this, I'm going to go back to my smooth display.

06:39

We're able to control the curvature in a smaller area.

06:43

And now we have what's called A T point.

06:45

The T spin functionality underneath the hood of the

06:48

freeform modeling allows us to have these T points.

06:51

But

06:52

there is going to be a caution that comes along with it.

06:55

We always want to be mindful of the edge in which A T point creates.

07:00

This is one of the only instances where we really want

07:03

the edges on both sides of this to remain co linear.

07:07

If you need to raise this edge up, for example, by using edit form,

07:13

we would want to be careful about the curvature

07:15

that gets created in this face. So we would need to use, modify and insert point.

07:21

And we would need to carry this down a little bit further.

07:24

As a general rule,

07:25

I like to carry that down at least two edges

07:28

away from the area in which I'm changing curvature.

07:31

While that rule is not hard and fast,

07:33

it does help us maintain a nice smooth transition of curvature.

07:38

If we toggle back to smooth display by using our shortcut keys

07:42

and we use control and four to hide our edges,

07:45

which can also be done under visual style and going to shaded.

07:49

You can see that we've got a fairly nice

07:51

transition of those two bumps that we just added.

07:54

I'm gonna go back to my display with visible edges only

07:59

and once again,

07:59

carrying those T points out a couple of extra edges away from where we changed,

08:04

our curvature

08:05

is going to help us maintain that nice smooth transition.

08:09

The last thing that we want to talk about in this

08:11

video is going to be a tool called slide edge.

08:14

For this example, let's go ahead and double click.

08:16

One of these bottom edges go to modify and select the slide edge tool.

08:21

Slide edge allows us to take a selected edge

08:24

and move it along its connected ends.

08:27

So for example,

08:27

if I want to slide this beveled edge a little bit further away at about minus 0.2

08:33

I'm able to gradually round out that transition a bit more

08:37

because we're moving the edges away from each other.

08:40

Remember that the curvature is controlled by the edges in our box display.

08:45

And the closer these edges are together,

08:48

the tighter that transition is going to be.

08:50

So if we use undo to see where those bell edges were

08:53

and redo to stretch them back out,

08:56

we can also see this in our smooth display.

08:58

If we use undo, we can see a tighter transition and redo separating them out,

09:03

gives us a more gradual rounding of those corners.

09:07

So using all these tools in conjunction with each other,

09:10

the insert edge, insert point,

09:13

the bevel tool as well as slide edge

09:15

can all help us control the curvature of our designs a little bit better.

09:20

Just remember that we always want to be careful

09:22

of having co linear edges next to each other,

09:25

meaning the edges are going exactly in the same direction.

09:28

And we want to avoid those planar faces that

09:31

are directly next to each other along that same plane

09:35

there will be exceptions to every rule, but in most cases,

09:38

those will be the general rules that you want to follow.

09:41

At

09:41

this point.

09:42

I suggest that you continue to play with this model a little

09:44

bit more inserting additional edges points using bevel and using slide edge.

09:49

And once you're done with that, make sure that you do save before moving on.
