When I save a CR2, I'm asked if I want to save it as a new geometry file or the original figure geometry file. I don't know what to choose (I've been choosing original figure geometry and I give it a new name). I used to see obj files created with my CR2s, but now there's pmd files. Can someone explain why I should make one choice over the other? Thanks.
