Extract curves resulting from the intersection of the sketch plane with selected parts.

Create Intersection Curves

  1. On the Sketch ribbon, select the Intersect tool.

  2. Select the parts you want to intersect with the sketch plane.
    The intersection curves are shown as a dotted red line or curve.
  3. Right-click and mouse through the check mark to exit, or double-right-click.

When a sketch plane is defined on the face of a part, the intersection curves are generated automatically. You can disable this option in the Preferences under Sketching > Show intersection curves on sketch plane creation.
