I just upgraded to 2013 SP1.0
I have a .step file that I need to recognize as a sheet metal part. I run feature works recognize features and the only thing it does is recognizes a couple of cuts (just holes). It does not recognize any flanges or bends. I still see the Imported item in the feature manager tree. Basically it does not do anything. This was not the case with 2012. I can use convert to sheet metal but does not allow me to edit any flange profiles, heights, etc. Also a change from 2012 I believe.
I unfortunately had to unistall 2012 due to disk space on my SSD so I am unable to test with the older version.
Has anyone else run into this?
