Hi, thanks for your post, but I can't help seeing it as anything else than a closed door...
All the additions in this thread are workarounds at best and make copying sheet metal bodies many clicks longer than it is with any other types of bodies.
It seems Autodesk made a fine tool for working sheet metal but - for no reason I've seen, read or heard so far - made something as basic and essential as copying and pasting sheet metal bodies a time wasting operation.
Your post from 2 years ago says "...is currently blocked...". While "Currently" loudly speaks of something temporary, 2 years is an eternity in the computing world. So, why exactly hasn't this already been addressed yet?
I know this may sound a bit like ranting - and it partly is I admit - but if there is no resolution planned or if it is a technical issue that cannot be resolved, users need to know. Likewise, if it is planned, letting users know if it is going to take another two years or not would be the least.
