- [Instructor] When you want to project a curve
from a sketch that you've already created
onto another surface,
you're going to use the projection curve feature.
It's pretty straightforward.
And in this example,
we're going to take an existing sketch
and project it down onto a surface extrusion
that I've already created.
So here we've got our sketch
and you'll notice it's above the surface, not touching it.
I'm going to go up to the Insert tab, down to Curve,
and hit Projected.
For this option, we're using the sketch on faces.
So first, I'm going to select that sketch.
And second, I'm going to select the face to project it on to.
Notice that the arrow here
indicates that it's going to project upward.
We want to reverse that and you can do that
by clicking on the arrow right here
or selecting the checkbox right here.
Notice that we've got our preview in yellow.
I'm going to go ahead and hit the green checkbox for OK
and we've created our curve.
Notice underneath the curve,
it's got the sketch that it's based off of.
It also shows the offset distance from the plane.
That's how you use the projection curve.
