Flat view, sheet metal not all flattened

[badgerdave]

I'm having some trouble, I'm matching up my SolidWorks drawings to a previous design and playing with the offsets of my end flanges. I know this is frowned upon but I don't think it should be causing me trouble.

My problem is I'll make changes and flip back and forth between the drawing and part to check if my dimensions are where they are supposed to be. A couple times now, I've had one or all of the flanges refuse to become flattened in the flat view. In the model, it flattens, also I can unfold it, refold it. Never gives me any trouble, but I haven't found a way to fix the drawing. I have just tried modeling it again and not messing with the flanges.

Anybody else see this before? Hints?

Ooops actually it will unfold, but when unsuppress the flattened view, it doesn't flatten.

Well some how one of the elements in the flattened view became suppressed. I had to unsuppress it in both the model and had to reinsert the flat view in the drawing. (I didn't try closing and reopening, that may also have worked)

Hopefully this helps someone else somewhere down the line!

Why are you having to go to drawing to check dimensions?
Attach a sample sldprt here. I suspect you are not using the best sheet metal modeling techniques.
