For some reason this part will not flatten?
Usually I would just re-draw the part but i have a lot of other references to it in my Assembly.
The flatten has conflict whit cut extrude future
1-Suppress cut extrude future
2- Do flat pattern
3-Un suppress cut extrude future
5- save your part
Right click on Flat-Pattern1 and select edit. Then pick the vertical edge.
