Any updates on this topic

What exactly are you asking about? Solar diagrams or light and shadows?

The solar diagrams didn't work for a while because of different versions of Pysolar available. This has been improved in the latest code, and it's now possible to create diagrams again; see Pysolar with Arch Site.

About lights and shadows, nothing concrete has been developed yet. If you want to obtain a quick render, maybe you could use the Raytracing Workbench to produce a quick image with POV-ray. You can also export your FreeCAD model to Blender, and render from there. See the tutorials section in the wiki, in particular the rendering section.

Oooh - I'd love to play with this.

Just a public question: does anybody else where use Radiance for sun / day / light analysis? I can think of lots of potential for integration here ...

What?

Did you mean to say, "does anybody want to do radiance analysis?"

Everything you can implement in solar calculations is welcome.

I'd love to see some Radiance integration in FreeCAD... Fortunately we have the right person here for that

Thank you for the discussion. Grasshopper(Rhino) has a plugin called ladybug. Its is an open source plugin. If something like that could be implemented in Feecad, it would be great. It uses epw data.

Is it this: https://github.com/ladybug-tools ?

It would be awesome exposure if there was a FreeCAD ladybug module
