This is the regression, the bug I tried to underline several times: in drawings, you can change sheet metal flat pattern bendline type NO MORE.
You could do that till SW 2010, now you cannot.
I updated to SP1.0, I get exactly the same problem. AND NOW MY DRAWING ARE GONE, AND THE MANUFACTURING GUYS ARE GETTING NERVOUS.
I sent the request through my VAR, but SolidWorks still ignores my voice, as always. Now I feel we're going backwards, and though I own several licenses of SolidWorks, I'm going to look outside, PTC maybe will be a partner I can talk to.
