Ok, it’s incorrect, but I didn’t understand the why. I have asked this ChatGPT and it said something like “breps are a “complex data” structure not suited for projection” Instead I should go with a mesh or contours.
After a search I found this post that told me I should use Mesh Shadow. This almost produces the result I desire. The issue is that Mesh Shadow shows an error and some “bricks” are missing.
