Create basic surfaces.
00:05
After completing this video, you'll be able to extrude a surface,
00:08
revolve a surface and use trim
00:12
in fusion 3 60. Let's get started with the supply data set basic surface dot F 3D.
00:18
In this design, we have three sketches, a trim, a revolve and an extrude
00:22
to get started. Let's show the extrude and hide the trim and revolve sketches.
00:27
While we're creating a solid extrude,
00:29
we can use a closed profile like this or an open profile like this for a thin extrude.
00:35
When we're using surfacing tools, we can use both of those profiles as well.
00:39
However,
00:40
using a closed profile with the extrude tool
00:42
is still only gonna produce the outside walls.
00:45
This is because our surfaces are going to
00:47
be infinitely thin representations of the geometry.
00:51
This allows us to focus our attention on portions
00:53
of the design without building an entire solid body.
00:57
If we hold down control or command and then select the other sketch entities,
01:01
you can see that we're able to extrude both of these at the same time.
01:05
And if we take a look at our bodies' folder,
01:07
you'll note that body one has a four next to it.
01:10
And body two has a three.
01:11
This represents the number of faces that make up that surface body.
01:15
Surface bodies are individual faces that are stitched together.
01:19
When we use a sketch such as a rectangle,
01:22
this will automatically create four surface faces that
01:25
are stitched together as one surface body.
01:28
We can use tools like unstitched and we can
01:30
select geometry to break those into their individual faces.
01:34
Now,
01:35
we can show and hide individual faces and we
01:37
can work on these designs as if they're one.
01:40
In this case,
01:41
let's go ahead and hide these surfaces and
01:42
let's focus our attention on the revolve sketch,
01:46
creating a revolve is very similar to creating one with the solid tools.
01:49
However, when we revolve a surface, once again,
01:52
we're going to get something that's infinitely thin.
01:55
In
01:55
this case,
01:56
our revolved surface only has one face because it was a single sketch entity.
01:59
A spline that was used to create this.
02:02
Now, in some cases, you might find that you're over building your surfaces,
02:06
you make them larger or further than they need to go
02:09
and trim them back to their desired shape or size.
02:12
This is often done for a few different reasons.
02:14
In some cases,
02:15
it might be easier to generate a larger surface and trim
02:18
down the areas that you want because the shape is complex.
02:22
In other cases,
02:22
it might make more sense like with the case of this trim and our revolve
02:26
to revolve the original design and use trim because the final
02:30
shape is going to be too complex for that revolve feature.
02:33
So in a case like this, we're gonna use the trim tool,
02:36
select our sketch line and then select the area of the design we want to remove,
02:40
we'll say OK. And in this case, we need to hide our trim sketch,
02:44
noting that we've now created a complex opening on the top of the surface.
02:48
This would have been impossible for us to do with a traditional revolve.
02:51
However, it is possible to do with the revolve and a trim.
02:56
We can use many different types of geometry for trims.
02:59
We can use a sketch, a plane or another surface.
03:04
In this case, when we select trim, notice that the planes are visible by default,
03:09
if we were to select one of these planes, for example,
03:11
the YZ plane and then select the front portion of our design.
03:15
We use that plane to trim our design.
03:18
Oftentimes this makes sense when we're working with symmetry to
03:21
focus our attention on just one portion of the design.
03:25
From the right hand side view.
03:26
Let's go ahead and create a new sketch, selecting the right plane
03:30
and let's simply use the line tool to create a complex shape inside of this area.
03:36
Let's finish the sketch,
03:38
select trim
03:39
and select our sketch and then the outside portion of our design.
03:43
Once again, we will need to hide that sketch and as we rotate it around,
03:48
we can see that we have a fairly complex surface
03:51
that has a border that would be extremely difficult for us to create
03:55
with that geometry.
03:56
So oftentimes starting with a simple surface or a basic surface
04:01
and then trimming it back or extending it out to where
04:04
it needs to go is going to be the best approach
04:07
for this example. Let's make sure that we do save what we've done before we move on.
