In the attached file I have a planar closed curve and a network of curves in red.
The sides of the planar curve are trimmed versions of the red network.
The precision is 0.0001.
If I use the NetworkSrf on the red network and create a planarsrf on the closed curve, I can join the two.
If, instead, use Sweep2 to on the red network, planar surface will not joint to it unless I increase the precision to 0.01 (1000x).
I was curious, why is this the case?
(and I am working on the tangents at the bottom).
