Project geometry to 3D sketch

Project geometry from the active 2D sketch onto selected faces, and create a 3D sketch that contains the projected geometry.

1. On the ribbon 3D Model tab Sketch panel, click Create 2D Sketch.
2. Then click a face or work plane to set the sketch plane.
3. On the ribbon Sketch tab Draw panel, click Project to 3D Sketch .
4. Click Project to enable/disable the projection of 2D geometry onto faces.
5. Click Faces to select faces and planes to project to.
6. Click Preview to view the projected geometry while you modify the 2D source sketch.

When you finish, a new 3D sketch contains the projected geometry. It is associative, and updates with changes to the original 2D geometry, unless you break the link.
