Set up the Intersect tool

• Choose Surface Edit > Create CurvesOnSurface > Intersect ❒.
• When you intersect two surfaces, you can choose which on which surfaces the curves-on-surface are created:
  • To create curves-on-surface on the surfaces on both surfaces when you intersect them, set Create Curves on Surface to Both.
  • To only create curves-on-surface on the surfaces on the first surface, set Create Curves on Surface to On First Surface.

Create curves-on-surface at the intersections between surfaces

1. Pick the surfaces on which you want to create curves-on-surface.
2. Choose Surface Edit > Create CurvesOnSurface > Intersect .
3. Do any of the following:
   • Click a surface that intersect the picked surfaces.
   • Click a reference plane.

   As you click, the tool creates curves-on-surface at the intersections.
