<p>Could you explain more about these two functions? Are they a plugin from Ladybug? I can't seem to understand what's going on, so any clarification would help. </p>

<p>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.</p>

<p>Hi David and team,</p>
<p></p>
<p>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 of casting shadows on flat planes using MeshMesh intersection also worked. The problem is that I can’t contour my shadows any more. Any idea how can I find a contour normal to each shadow?</p>
<p></p>
<p>Thanks.</p>

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 surface. take an inclined plane parallel with the rays of the sun, the rays would never actually hit that surface and the shadow would consume the whole thing. whereas in the approach you describe they would...what am I missing? is there a quick way to…

<p>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 different approach...</p>

Thanks for your time and help! I projected the shadows onto my surface, but is it possible to make the shadows into a volume vs just an outline?

<p>I guess that's what I was thinking if adding another input doesn't irk your component consistency standards (for the 10% of the time it might matter).</p>
