Hi gizmo,

That's great that you sorted that out.

> I'm looking to use it as a quick and dirty way of creating difficult geometry that will be rendered in other 3d apps.

Yeah, most of us are using it for that and there are a few people using it for work as well, but it's more like a quick and 'clean'
way of creating difficult geometry because the geometry is just as good as any other cad package.

Hi Paul,
Using the blend method is a top one too, I always forget that one and the funny thing is that I use it at work all the time but it's called bridge curve.

Cheers
