[PSUBS-MAILIST] Reverse engineering in CAD

[Peter McKellar <submckellar@earthlink.net>]

Hi All,

I am trying to reverse engineer a boat hull for my pressure hull's exo-skeleton.

I am using autocad 2004 and solid modelling, but i just can't split the shape into the primitives i need to draw it (in my head anyway).  I am also trying to scale it down (and this has its own pitfalls as it may not scale and retain its properties).

I have a jpg of it, including cross sections both horizontally and vertically at a number of points.  I am considering pasting these planar jpgs into the drawing and then doing a 3d join-the-dots.

can anyone think of a better solution?

cheers
peter
