"Hi Danny, Thank you for your response. Please disregard my question. I was able to figure it out on my own. I simply  projected my shadow lines from a flat plane to a free form surface. It worked."

"Hi Volha If you upload your files to I can look into for you."

"Hi David and team, I am wondering if someone can give me a few tips on how to handle curves after MeshMesh intersection. I am trying to contour casted shadows. It works fine on flat planes as you can see on  attached jpg. David’s method…"

"I'm trying to do the same thing, with no luck so far. I want these shadow 'wedges' so I can boolean them out of my site volume.   I've been trying with a simple box (see attached).  I made the mesh shadow, then moved it…"

"I figured it out, and spoke too soon. if anyone's interested in the solution I would be happy to share. I used MeshRay and the Delaunay components...."

"I need this very thing for some shadow studies - but maybe im getting something wrong but the projection of a shadow outline back onto a freeform surface does not seem (in my mind) to be the same thing as the vector rays of the sun hitting that…"

"Can I just ask, when you talk about hiding the geometry, are you aware of the Enable/Disable Preview settings for each component in GH. These have now moved to the Radial Menu in v0.8.0050 accessed by the middle button. Previous versions had them on…"

"maybe solid difference or trim solid?    "

"Boolean Difference might be the solution to this."

"Can you post the definition? Chris"

"Try using 'List Item' to get the specific BRep you want."

"I have been looking at discussions and I think I test my trimmed object to see if a point is inside the breps that I trimmed against and then use cull to remove those areas... but I don't know which cull to use or how to go about it"

"yes, but how then can I hide/delete the areas that are intersecting?"

"'Trim Solid' should do the trick."

"Sorry, I was being more theoretical-- I attached a photo of what I meant.  Its not really technically correct, but, in this instance, the shadow would make a wedge-shaped volume.  If there is no easy way about this I may search for a…"
