I have been using the sheet metal feature to flatten RHS section to make a profile for easy fabrication. This has always worked flawlessly until now. I created a sheet metal feature from a body in my part, check that it flattened then moved onto the next body. when I went back to create the flattened configurations by unsuppressing one sheet metal feature per config. I found none of the features would flatten properly. The bounding box is shown and the rest of the part is hidden, but the body remains in its folded state
This successfully flattened when created, but will no longer display correctly.
