Hopefully a quick one - I have created these two planar surfaces, same shape and area - each the result of chopping down from separate larger solids. They are planar and I’ve specifically moved them to be horizontal and on the same z value (z=0).
When I use the Rhino (v5) Intersection command, it says 0 interections found.
I’ve tried to call Intersection.BrepBrep in Rhinocommon too and received the same result: though the function returns True (successful calculation), it returns no intersection curves.
Can somebody tell me what is it about these two surfaces that causes that result? As far as I can tell and understand, they definitely should result in an intersection curve that is basically equal to their edge curves.
