Issue with the Ladybug´s CountourMesh component

Hallo Everyone,

I have one question about one component of Ladybug.

I need to simulate a sunlight hours analysis over faces of buildings, but when a try to generate the contour mesh (Even just a facade) appears this error “The connected inputMesh is not planar and this component only works for planar meshes”

Is there a way to fix this problem?

Best Regards


This component works with planar meshes only. Since you are interested in looking at sunlight hours on one Facade only. Only provide that facade as a surface in _geometry input and it should work.

Hi Sonny Weaver,

Sure, a facade surface can be supplied quite similarly. Please find revised sample. Hope it helps. (406 KB)

Dear mr Chauhan,

I attached a simplified version of my work.

I can not find the solution with his method (which in his example works).

I hope you can solve the problem by taking a look at the files.

Many Thanks

Best Regards
