Aligning normals across a variety of surfaces

[Joseph_Oster]

Well, well, hello again. This has been on my mind since your other thread yesterday:

Orienting array of panels works for 1 surface but fails on multiple

I’m trying to create an array of surfaces across a diverse variety of plane geometry. I’ve built a script that that reliably creates an array of panels on any sort of quadrilateral. However, when I try to apply this to multiple surfaces, the script produces strange results, beginning at an orient command about halfway through the script. This seems to be something with the data from multiple trees misaligning, because I can gain some sort of improvement by flattening some of the incoming data; h…

The first thing I did was flip all the roof surfaces so their normals point up, using Flip with a PlaneSrf as a guide. But I didn’t stop there.

I see you are still using Pufferfish for Rotate Plane XYZ ?

P.S. Here is your new set of roof surfaces:

You didn’t answer my questions yesterday:

Parallel to one edge of the roof? Bottom edge? Top edge? How does this work on roof surfaces that face north?
