Hey I’m having bit of an issue.
I have made at script which measures the first point of contact within a Room to given categories of elements.
To do this I use the Point.Z on the OTTB RayBounce.
This gives me 2 values. The starting point from the room, and the to the first element encountered.
I the subract these from each to get the actual height. This works perfectly.
But now i wanted the scrip to be able to take linked elements into account, som i used the “RayBounce On Linked Model” from DataShapes. But with using this i don’t get the starting point only the toppoint. Is there someway for me to get that startning point extracted from this node?
Hope this makes sense, I have added a simplified edition of the script that shows the different output
You already have the starting points in the GetLocation node.
If you want a similar list structure to the OOTB Raybounce node add a List.Create and a List.Transpose nodes.
Hej Alban
Thank you. I didn’t even think of that!
But it seems to work.
But the results I from the OTTB- and DS-Raybounce is still not the same.
But now it is actually not the start point that is wrong, but the top point.
Maybe something wrong with the DS-node?
If you see list 4, i dont get the same results?
I too am curious to know that from where the OOTB node gets its reference/datum value for the striking point? I also changed elevation of project base point but the result of the “Points” value from ootb remains same.
Just figured out that it is from “Project Origin”, not project base point.
Hence if someone needs to set a relativity with levels and offsets, it might pose some issue.
