This may be a bug, but more likely user error. :)
I'm trying to build a relatively complex surface. I need to shell it, because it is a plastic part that will be eventually turned into a mold, but I can't get the pwr_shell to work as I need it.
To start, I've simplified it (example in attached max file). I have two surfaces that are offset from one another, that are created using rail sweeps. I create a pwr_sketch to act as trim lines, and trim them so there's a gap in between the way I want. I then create another sketch to define the surface in between, and create it with another sweep using the edges of the surface cuts. I have to increase the rail synch to make the surface conform in some cases. (First model on the left at this point.)
Now if I shell one piece alone (next to right), it works fine. Then (next, to the right), I join them. The NURBS Query tells me that I have the number of open edges as I'd expect. If I shell the join, I get a few different options; 1) I get a box, which I assume is the "I've failed miserably" default, or 2) I get all kinds of open edges, notably at the lower corners of the join sweep.
If I play with settings within the stack of the part, different things happen. Usually it goes to a box. Sometimes, the spanning surface will change; the sketch points drop, move, it connects itself to other edges of a sufrace, and so on.
This is driving me nuts, and I have a deadline...
Thanks for the help...
