Basically NURBS modeling works really well when you are driving much of the design from 2D profile curves, using some of those curves to generate large extended shapes and then using other 2D curves or other generated solids to cut pieces away.

The less that you are able to do things along that pattern, the more difficult things will be and the more things tend to become more suitable for sub-d modeling 3D cage driven workflow rather than 2D profile curve driven workflow...

Yes, this is exactly what I have to learn.

I know, its impossible to help me out here with my spare comments.
I for myself cannot reproduce the stages, where I had those problems, but
as you said, I have to think different here (larger shapes and cutting/trimming away)

thanks very much for your support!

Hi mike, yeah focusing on using cutting operations as a main way of working is usually a big adjustment for people coming from a sub-d modeling background.

Check out here for some links to discussions and general tips for people who are coming from a sub-d / poly modeling background:
