Notes

  • If you have the Length field locked, Mastercam creates two tangent lines and asks you which to keep.
  • If you pick a tangent point not on a selected arc, Mastercam moves the point onto the arc. It does this by projecting the selected point along a vector from the point and through the arc’s center point.
  • If you pick a tangent point not on a selected spline, Mastercam moves the point onto the spline. It does this by using the Nearest function to project the selected point.
  • After you choose Edit Endpoint 1 or Edit Endpoint 2, you can use AutoCursor to reposition the endpoint.
