RAM Frame Polygon intersection algorithm

Question

I receive an error message "Polygon intersection algorithm failed for the following input polygons:...." when I open RAM Frame. Once I click "OK", the RAM Frame module closes. I don't understand why I'm receiving this error. The only change I made in the model before receiving the error was I added bracing members in a few bays.

That's a pretty old version, but I still see your error in Ram Frame. 
 The 3D view gives some clear evidence of deck polygon problems: 
 
 For more on laying out deck polygons on a sloped surface see: https://communities.bentley.com/products/ram-staad/w/structural_analysis_and_design__wiki/7207/ram-ss-3d-viewer-faq 
 In this case, for example there is a transition from a sloped area to a flat area that requires two deck polygons. Try not to overlap the deck polygons in roofs like this.

You will find some detail on that here: https://communities.bentley.com/products/ram-staad/w/structural_analysis_and_design__wiki/4552/ram-ss-common-framing-table-errors-tn 
 If it's happening in Ram Frame, prior to analysis or meshing, then it must be in the routine to determine total masses and gravity loads or exposure boundaries.
