I have a lifting lug that is bent which I have modeled and then flattened out for burning.
A while later it was revised to show a 75 dia hole.
So while in the flat state I added this new hole, however when I went back to the folded state the hole disappears.
The only way to have it shown in both flat and folded states is to add the hole while in the folded state.
Why should it make a difference in what state (folded / unfolded) I add any extra features.
