a little thing to know about sheet metal...

    Hi all,

    I discovered something interesting today using the unfold and fold commands
    on a sheet metal part. (excuse if this has been mentioned before)

    I needed to flatten a curved face out to locate some holes on that face so
    I unfolded the part and because I'm lazy I usually just click the 'collect
    all bends' button.

    In this case however, after folding back up the part I had errors in my
    assembly. Investigation revealed that after being re-folded vertical and
    horizontal elements of the sheet metal had been rebent inaccurately.

    The errors were in the range of 0.00000018° from vertical or horizontal but
    that is more than enough to blowup any mates or in-context relations to
    those edges or faces.

    In this case I solved the problem by only unfolding the single curved face
    I needed.

  2. I've noticed the exact same problem too. What I use as a rule when I need to
    flatten anything, only flatten what you need to, to accomplish what you're
    doing.
