Well, I think that paper approach is flawed for many reasons...but as a CAD designer (at least my colleagues think I am

) I know that drawing a 3D horse is difficult as h*ll, and I gave up
If only I could get my hands on a horse sculpture or mannequin I could attach force sensors to each hoof and measure the CG...shame Christmas is so far away

I have the force sensors in my drawer

Or, if I had any artistic skills whatsoever I could make one in silly putty, that way it's easy to form into SI etc

But no, I have no artistic talent, either

Only force sensors
