3 View To 3D Model To Internal Structure

I want to get into some designing and have a good amount of CAD experience (autocad inventor/catia). Unfortunately none of it is anything aircraft related.

So my main question is where is the best information on how I can take a 3 view and turn it into a 3D model and then what is the process of creating an internal structure. I have done some experimenting, and had limited results.

Any ideas on where to start. I have some ideas but was wondering if anyone had any tips or suggestions to steer me in the right direction!

I hope to compile this information and make a guide for others who may be in the same boat as me.

For Wings and Fuselages you can see devWing and devFus:
They produces a cosmetic 3D and the DXF files of the single parts ready to cut.

The basic process in 3D CAD programs (I don't know about the dev* programs, because I haven't used them):

1. Trace outlines in the different coordinate planes. When tracing, it is important to preserve symmetry. For shapes that are supposed to be symmetric, it is best to trace only half of the outline and then mirror it to the other side.

2. Trace any additional sections, formers, or other important details provided in the 3-view and place them in the proper location in space.

3. Create 3D solids or surfaces by applying operations like extruding, lofting, and sweeping to the traced shapes. It may be necessary here to use your best judgment to add supplemental shapes or other information that was not included in the 3-view (that is the real tricky part).

4. Use section cuts, intersections, boolean operations, etc. on the 3D solids and surfaces to create the internal structure.

That is a very simplified overview of the process. Of course, many of the steps require a lot of experience and/or trial and error to get them right.
