Modelling is very quick in 2007 now.

We draw up whole power stations here so we need to use a proper cad package.
Getting these through to Vue has always been a bit of a problem. We strike the 65k limit with 3DS the whole time & have to export individual parts outs to get around it.
A think for Vue to become more of a professional business tool, & not just an art program, it needs to support a serious cad program, not to mention real units.

I had hoped to try the free version of Amapi as you suggested, but it seems to have gone.
