I'm trying to project an edge of a cylinder in a "detail" view. Here's the process I'm taking. Click the view and pick "create sketch", then I pick "Project Geometry". Then I pick the edges of the cylinder I'd like to project and it only projects one side. I can select the edge, but when I right-click and pick done it won't project it. It appears to me that it's only allowing one edge of the same object to be projected. I've tested other objects and it seems to only do this with cylinders.
Can anyone tell me what's happening? Is this a setting or a bug in 2012?
Attach the files here that exhibit this behavior.
You probably should have attached the drawing file as well.
It works on my machine.
I noticed that you have not installed Service Pack 1 - you should probably do that first and reboot the computer and see if the behavior persists.
