I have now given Blender a good test, and I am hooked. The user interface is a bit weird at first, but it grows on you, and I expect it to be quite easy to use once I get the hang of it. The software features are perfect for this: GNU Free software (...) (20 years ago, 8-Mar-05, to lugnet.cad.dev)

Many thanks. If you need any help with it, just ask, and I'll try and reply with concise instructions. One of the biggest problems I find in writing instructions is what to include - too little, and you can't get started, too much and you drown in (...)

As some of you might have seen, I have been doing some programming lately to convert various 3D file formats to DAT format. This resulted in the MAX2DAT converter, which is useful but does not handle primitives, and is limited to the file formats (...) (20 years ago, 5-Mar-05, to lugnet.cad.dev)
