The Project command projects geometry from outside the active sketch onto the sketch plane so that you can reference it in Fusion.
Design > Sketch > Create > Project/Include > Project
Use project geometry to create copies of existing model geometry and sketch entities in the active sketch.
You can project model edges, work geometry, and sketch entities into the active sketch. Projected geometry is locked by default.
If you create a sketch on an existing planar face, the edges of that face automatically project into the sketch.
Select the bodies, faces, edges, or points to project onto the sketch plane in the active sketch.
Select an option to filter the selection set to certain types of geometry.
Establishes an associative relationship between the selected objects and the projection geometry on the sketch plane.
