Chappy - how do you do the complex glasswork for the 2D (and others) ?

I make vacuform windows using one of those dental machines off Amazon.  I use 3DP bucks which are smoothed and sometimes primed before use.  The Mirage was done this way.

   

I suspect the question really is "How do you make the shapes for the form/buck".   The best answer is to have a file with separate glass sections, as that makes it easy.

Lacking that, fitting shapes to the body can work, but involves some shaping CAD work. AlexisinGreece has done a nice tutorial for using Blender, which is free and very powerful.

In some situations I have used CAD to cut the cabin off the body and use it as a "negative" buck.   This works, but requires upsizing and more trimming for the glass to fit.
