Hey,

I have been trying to run Sun path on ladybug but to finish it because of the error (Image attached below). I searched in forums but unable to find a fix for this.

Looks like another user has run into this issue as well, see this [GitHub issue](https://github.com/ladybug-tools/ladybug/issues/145). Chris Mackey (Ladybug co-founder) recommends exporting your geometry from Revit and doing the analysis in Rhino/Grasshopper instead.

That can be done. But would that be an issue in terms of creating a BIM Model …

I started using Rhino and grasshopper, it works over there.
