I was wondering if anyone an see the logic behind this. We were having a problem sweeping a polygon along two curves.
The curves are quarters of an oval with a w:h ratio 1:3.
Here’s the weird part:
It seems that when the rails are going up in the Z-axis we can’t sweep the polygon as it creates geometry that is clearly wrong, if the rails are going in the XY plane, then the sweep works fine.
Does anybody know why this is happening, is this a bug? Is it something about the inherent logic within Rhino?Sweep 2 Bug.3dm (208.6 KB)
