Thanks for the quick replies. I think the split/slice might be what I need. Haven't addressed that tool yet.
SU is really quick and easy--and even more easy to ignore good object organization. This then transfers wherever it is imported.
I've read a tutorial about importing SU files and that worked well. The writer did talk about setting up the hierarchy for the import into Maya. I did not do any of that though. I understand the parent/child elements, but wonder if my SU methods might not work exactly right. Here is what I do
In SU the safest and fastest way to work is to draw everything on layer 1. Then after the objects are completed, group and/or component-ize them. I then make separate layers for the group/components and move them to their own layer. e.g a walls layer, a floor layer etc. I expect that within Maya I can then assign Parent/child attributes. e.g., wall parent with railing as the child.
Anyway, I'll try to play with this further.
