like wires, and because of this, it is very easy to adhere a projected curve
to the shape of the surface. e curve will maintain the surface contour if
the surface is changed.
What can we do with this curve now that it has been projected? e
rst thing we do is use it to create a trim. In order to create a trim, we
need a closed or periodic curve. You can see how generating a trim sur-
face will “cut” a hole in that surface in the exact shape of the curve.
Alternatively, you can create a surface with just the projected curve, which
will leave you with a surface in the shape o ...
