Project geometry symbol is red in Inventor.

[Anonymous]

I drew a circle, extruded it, added a chamfer to one edge, then created a shell. Now I'm trying to create a sketch on one end, it won't let me project geometry.. It's allowing me to project cut edges and 3D sketch. In my tutorial project geometry is on. How can I fix this?

Okay, brief demo of project geometry vs project cut edges.
