Enclosure and "merge parts?" option
 

Hi,

I have already my model in DM with the original tree structure, but when I regenerate after creating the enclosure with option "merge parts?" to yes, I get all the structure in one big group. :(

So it's complicated to find something.

Isn't there any possibility to keep the structure?
Is the "merge parts?" option mandatory if I simulate some metal and plastic parts in air?

Then it would be good the possibility to sort the parts for helping finding something. But there's no drag and drop options and I think I have to accept list like DM does automatically.

Thanks in advance

it should not be merge part, it should be frozen !!!
