algorithmic modeling for Rhino

When the projection direction is very close to the projection plane's normal, the result is the same as the usual Project component.

Yeah there is a one-degree tolerance check to see if the projection direction is parallel to the plane Z-axis, and if it is parallel then the transformation is just a straight planar-projection.

I've tightened the tolerance to 0.01 degrees now.

Thanks,

I was about to ask why not using the rhino tolerance, but I just noticed it is 1 deg by default.

So 0.01 probably better.

And if ultra accuracy needed (which is my case at the moment), I guess using this or extrude+intersection will work.
