I think I’ve found something strange. I have a pair of intersecting surfaces and I copied them to create two identical pairs of surfaces, differing only by their X and Y coordinates.
When I perform an Intersect call on each pair, the resulting curve is different (the right one appears to be incomplete in that it doesn’t extend far enough to the lower-left):
Am I going crazy? Does anyone know why this happens and/or how I can spot when this will occur so I can work around it?
On a related note, something else that’s confusing: when I use the left-pair’s intersection curve to split the swept surface, it results in 3 surfaces, not 2.
Any help or insight on these observations would be much appreciated.
