Hello,

I am modelling a tank using multi-body sheet metal.  If I isolate one part to make some cuts, all of the other parts disappear as expected. However, when I am applying my sketch lines, SW acts as if the other parts are not hidden. ie. I cannot select an edge of the part I have isolated because there is another part in front of it.

Is there some kind of option where I can turn this functionality off, or is it yet another reason to stop using multi-body parts altogether.  They are very nice to use most of the time, but when they don't work are very frustrating.
