- In this video we're gonna be explaining how
to use the Up to Surface command that's available in many
of your extrude solids or extrude surface commands.
First things first, let's explain the situation.
I have a rectangular sketch down here and I want
to extrude that up to this surface here.
Actually right now though
I don't have one surface, I have two.
So I have a surface here and I have a surface here.
And let's see what happens.
So first thing, I'm gonna click on this and I'm gonna click
on Features Extrude and it's gonna extrude it up
just like it would normally.
I can type in a value and away we go.
But I also have the option to extrude up to a surface.
And it's gonna ask me which surface I'd like to go to.
I'm gonna choose this one here
and it's gonna have a problem
because this surface here is
not fully enclosing that boundary.
So it doesn't actually know how to end that feature.
So we need to go back and fix that up.
We can also try choosing the other surface here, this one.
And it puts the exact same problem.
Okay, so what I wanna do is I wanna go back
and I wanna merge these two surfaces together as one.
So I'm gonna go to Surfaces
and I'm gonna use the Trim Surface first.
I'm gonna use this as my trim tool
and I'm gonna trim this away.
And click okay.
And then do the exact same thing one more time.
Trim Surface, I'm gonna use this as the trim tool
and I want to remove this.
And click on okay.
Now I have the basic shape.
Then I just wanna go and click on Knit Surface,
grab this surface here and that one there and click okay.
And now I have one uniform surface.
If I go under Surface Bodies, you can see there it is.
And now if I try to do the exact same thing I did before,
go to Features, Extrude Boss or Base,
choose this sketch here which is sketch three.
And I say Up to Surface,
choose a Surface here.
And then you can see, then it totally works.
There it is, then I can go back and hide that Surface Knit.
And there's my shape.
So a very powerful tool, just gotta make sure
that whenever you're using an Up to Surface command
that you are terminating the feature completely.
If for some reason you have a surface
and it's not the right size,
you can always use maybe an Untrim Surface
or you can extend the edges of the surface.
Or you can knit it together with other surfaces
to finish the boundary to make sure that fully covers
whatever you're gonna be extruding up to.
Now you can use that both with the regular extrude
or you can also go over here to Surfaces
and use the Extrude Surface as well.
So either one of those will work with
that end boundary condition.
A very, very powerful tool, I use it all the time.
