cnc scaning?

Take a side view photo then a plan photo of the board. e.g. http://www.mycncuk.com/threads/7823-...0995#post60995
Import into CAD and trace the outlines or use Inkscape (free) to trace them. Orient the traced outlines on the X and Z azes then do a '2 rail sweep' to obtain a solid 3d model, Rhino3D does this great.
Use the control points on the curves to fine tune your shape. There are videos showing this.

This one uses the similar 'surface from curve network' ;http://www.youtube.com/watch?v=BRRIBptfFxg

I'm thinking you could make accurate cross section drawings at various points along the surfboard and the CAD software would draw the in between parts to create the solid model.

Would it be more accurate to use the hand held scanner fixed to the router to get a very smooth slow pass. ..Clive

I don't mind spending the cash if its a good product and not over priced I would rather get it right first time than wase money on cheap half way solutions that end up wasting a hole heap of time. I have tried the photo method and its just not accurate enough to work from which I why I started taking manual measurements with the disto. I will contact prototools and see what they have to say about there product tomorrow. Basically it is just a series of cross sections I need to take down the board and one running length ways. It may be able to be done with some sort of probe even possibly?
