Almost all CAD programs will give you 2D drawings from 3D drawings. I know
of none that will easily/or even with a lot of work give you 3D from 2D
drawings. However, if you are building a scale model, a good set of 2D
drawings ought to be more than sufficient to draw up a set of builder's
plans. There are many programs that will convert a scanned in raster images
to a vector format (all I've tried don't do this without a significant
amount of work). Once in a vector format, the rest is easy....to get to 2D
builder's drawings. In the third place, 3D drawings are of questionable
value to build a model anyway......

No cad program can do this automatically.
