Modify at Intersection panel
Use the Modify at Intersection function to edit wireframe geometry wherever it intersects with a selected solid face or body, surface, mesh, or solid sheet body. Trim or break the intersecting lines, and create points without creating extra geometry or temporary planes. By default, Mastercam keeps the wireframe entities on the normal side of the surface or solid when trimming geometry. Click the Reselect button on the function panel to reverse the results of the trim.
Modify at Intersection can create points for drilling, measuring, or any other use. It is particularly useful to prepare tool vectors for Multiaxis toolpaths.
