With Boardcrafter Design’s ability to print snowboard templates at 1:1 scale using a standard printer and the introduction of the free shapes library the need for preprinted templates has been eliminated.

The snowboard templates previously available in the Boardcrafter shop have been removed. The shop still provides component snowboard materials and software registration keys.

One slight correction. My geometry is off for the part where you correct the Camber after offseting the distance between contact points. The equation should be:

New Camber = Camber - (Camber * change in EE / (2 * EE))

The way I drew it, the camber was being increased to correct it, this is wrong.

Shadly,

I think you are on to something with this but I don’t think I fully get it yet. In the proof you say “any offset to the base will increase the distance between the contact points. But, because the tip and tail radii (r2, r3) are lessened, the overall change in length is not effected”

My main question is if you have both r2 and r3 offsets biting into EE wouldn’t EE be decreased because you basically have 2 offsets going against 1?
