Custom Boxes and drink carriers to be done in CAD-this will require alot of R&D for some of my ideas but I think will be well worth it.
so it looks like this thread will be getting longer. LOL;)
I recommend trying Google SketchUp. It's free, and am I the only one who thinks Google software is exceptionally easy to use? There are a few designers here who are self-taught in using it. I have only a little experience, but it was very user-friendly and intuitive.
Good luck with it! Let us know how it goes!
