Sunlight hours analysis grid

Hi all.
Just trying to work out how to fix the analysis grid for sunlight hours on trimmed surfaces???
I get triangulations and too many points etc… I dont know if I have gone down the incorrect path for this test. Your help would be hugely appreciated.
Cheers
Brad

This is what is happening

Trimmed Surfaces

What can I input into grid size?

Or should I be going down this kind of path??

This is the result I would be after…

Hi @bradshales,

I suggest you work in meters instead of millimeter, decrease grid size and check this discussion: Uniform Grid Discussion

Best,

I’ll give it a shot. Thanks.
I was just trying to get a streamlined workflow with rhino inside.

Still getting some funky grids in meters…
Mainly around the small trimmed areas.

The problems with the concentrated mesh faces will probably be resolved by rebuilding the curves. It probably has several small segments. Also if you use the component that @AntonelloDiNunzio suggested you should not face this issue.
