I've got a part in Inventor which I am trying to duplicated in SolidWorks as I evaluate its capabilities. I've gotten the overall shape to flatten, but in order to add some of the more complicated features I need to unfold it. So far, that has eluded me. I can unfold a single roll, but once it's L-shaped it won't let me select a fixed face. Here's an image of what I'm trying to duplicate from Inventor, but the specific features are not as important as getting from the basic shape to an unfolded one.
