To Use Cross-Part Sketches to Create or Modify Parts

When you edit a part in an assembly, geometry from another part is projected into an active sketch.

Create or modify your part:

1. Create or edit a part in-context of an assembly.
2. Create a sketch or edit an existing sketch.
3. On the ribbon, select Sketch tab Create Panel Project Geometry and select the edge, loop, face, or sketch geometry.

   To indicate the new sketch dependency on another part in the assembly, a Reference sketch symbol is nested under the Sketch symbol in the browser.

4. Use the projected geometry to create a feature.

The new part is adaptive and updates when the parent part changes.
