How to Create a Surface Array from Interpolated Surface?

Recommended Posts

I created a roof with a (NURBS) interpolated surface but I'm not sure how to create a surface array to add 2x12's and purlins.


I might be able to fake the 2x12's (texture) with materials but I would still need to figure out how to extrude the surface 1.5"

@Pat Stanford and @michaelk thanks for your help!


Decomposing the interpolated surface into NURBS surfaces before creating surface arrays worked!


I was able to create fairly complex array items (with materials) to align the purlin ends flush with the roof trusses. I converted the framing members into symbols to keep the file size down. There's definitely some wonkiness in the details but this was a huge step in the right direction.


Going to drape a roof membrane onto it tomorrow...
