Hi All,

I have searched multiple posts in different Revit forums posts but I could not find a clear resolution to this problem. It seems this is a long-lasting item that Revit does not seem to work well with.

I have a conceptual mass and I pushed/pulled some of the edges to create a faceted surface. Then I added horizontal and vertical Reference Planes with defined names. Note that the divided surface UV layout is set to “None”.

Then I use the “Intersect” feature with the Divided Surface to get my custom UV layout. But no matter what I do, I get this error [Not all intersecting references (levels, reference planes or lines) could be used to intersect the surface]. Then when I apply a simple curtain panel pattern base on the divided surface, some panels do not get placed.

I will appreciate any help or pointers.
