Use surfaces to replace faces.
00:06
In this video, we’ll use replace face.
00:11
In Fusion 360, we want to get started with the supplied dataset complex box.
00:16
This complex box contains a box and a surface.
00:20
We want to talk about some tools that allow us to replace the top face of this box with the surface that we're looking at.
00:27
If I view this from the right hand side, we can see that the surface is a simple extrude that's made up of a line and a large arc.
00:34
But the process will be the same no matter how complex your geometry is.
00:40
When we want to take a look at replacing a face, if we go to Modify, we have a tool called Replace Face.
00:47
When we select Replace Face, we first need to select the source faces and the target faces.
00:53
When we do this, the source will be the top of our box.
00:57
I'm going to select tangent chain and the target faces are going to be the surface bodies.
01:03
When I do this, it's important that I select surfaces that extend past the face that we're replacing.
01:10
This is the only way that Fusion will be able to actually extend the geometry up to our selected surface.
01:17
Let's say, OK, expand our Bodies folder and hide the surface.
01:21
So what we've done is we've taken that extrude and we've taken it up to that surface.
01:26
Of course, there are multiple ways that we could do this.
01:30
We could use our sketch and we could extrude up to that object.
01:33
So if we hide Body 1 but we show Sketch 1 and we show our surface body, we can use extrude to take that up to a distance of two objects.
01:44
Keep in mind that there are some options, for example, adjacent face.
01:49
But because we're dealing with an arc, in some cases it actually wants to carry that arc around.
01:54
Fusion 360 is intelligent and the fact that it knows what we're trying to do and it extends the tangency of that edge out.
02:01
But this doesn't work in all cases.
02:03
In some cases, Replace Face might be the only option.
02:07
Well, let's see what happens if we make some modifications to this design.
02:12
First let's take a look at adding some fillets.
02:17
To do this, I first want to roll back before the replace face and I'm going to begin modifying this body before I make any selections.
02:25
So if we just add a large fillet on these corners, let's say 15 mm and then we roll back pass to replace face,
02:33
notice that it is still able to extend that.
02:36
The original face that we created here is still valid even though we've rounded the corners off, that selection is still there.
02:44
But what happens if we add a fillet to the upper edge?
02:48
In this case, I'll add another large fillet 15 mm, say OK and let's roll this back.
02:54
Well, Fusion was still able to extend that.
02:57
Because there was still a single face selection in the center, it was able to bring that geometry up including the fillet.
03:04
So it carried the fillet and it propagated around the new replaced face.
03:11
Let's take a look at what happens if we were to try and shell this.
03:15
Before I do that, I'm going to go to Inspect, I'm going to create a section analysis that's going to go right through the middle of this.
03:24
Then I want to go to modify shell and select the bottom face and I'm going to have a 1 millimeter wall, something that's extremely thin.
03:33
So I've created this shell and then I dragged this ahead to the replaced face.
03:38
Notice what happens.
03:39
It extends the geometry but it does not carry that internal face with it.
03:44
The shell is still in its original position because it was calculated before the replaced face.
03:51
One thing that we can do however, is we can drag these around.
03:55
If we shell after the replace face, you can see now that we have that consistent 1 millimeter wall thickness,
04:01
and it does respect the new face position.
04:04
So while some things will be able to be updated based on replaced face, like fillets on the vertical and the horizontal edges,
04:11
there are certain features that are still going to be timeline dependent, things like shell,
04:16
because it's not going to recalculate the shell based on the new position of that top face, but it will carry those fillets up with it.
04:25
At this point let's navigate back to a home view.
04:27
We can hide the analysis and minimize our folders, make sure that we save this design before moving on.
