When I send my parts to get formed from a flat pattern, when I send it to they bend the parts using ID is there a way to unfold the part and select the ID bend lines to show up?
I'm thinking you may not be modelling in the Sheet Metal environment as there is a large GO TO FLAT PATTERN button on the Sheet Metal tab. This shows the bend line and bend extents based on your Sheet Metal Styles. Both of these can be shown/hidden in an IDW view of the part Flat Pattern.
Hope this helps. A screen capture of the part (or attaching it) would be helpful. Remember if attaching the part to roll the EOP up to decrease the file size.
