About the Intersect Feature
With the Intersect, tool you can create a curve at the intersection of a surface with other surfaces, or a surface with a datum plane. You can also create a curve at the intersection of two sketches, or sketched datum curves that become surfaces after they are extruded.
You can use the Intersect feature in the following ways:
• Create three-dimensional curves that can be used for other features such as sweep trajectories.
• Show if two surfaces are intersecting to avoid possible gaps.
• Diagnose unsuccessful cross sections and cuts.
In the Intersect tool, surfaces can only intersect other surfaces or datum planes. Sketches can only intersect other sketches.
