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.
Welcome to the forum James,
First a quick check, have you done a Ctrl Q rebuild? That may reveal the source of your problem. From what I see in your screen shot, chances are there's something about your geometry that is interfering with flattening. Would you upload your part file? The advanced editor will allow you to attach a file.
