Hello,
I want to use the Room.CenterBoundary but with MEP Space.
I tried to get element geometry, then boundary but i can’t find the center boundary.
How could I do a work around to get this ?
Try this,
Hello Steven, thank you for your reply but in this projet we use MEP Spaces instead of Rooms.
So I managed to do it this way :
Is that giving you what you want? A bounding box would is just that a square box. Room.CenterBoundary is the center line of the rooms bounding elements and will hold true to the shape of the room.
I was thinking you could pull the rooms from the architecture model like this. (I think you need archi-lab and springs.nodes)
If what you are doing is giving you the results you need then please mark this post as solved.
Yes, thanks to the node “BoundingBox.PerimeterCurvesByNormal”.
I will mark it up.
Thank you !
Starting with Dynamo 2.6 (I believe) Space.CenterBoundary as well as others are included. However, I needed to replicate Space.Boundary node functionality with a Python script for backward compatibility. The heavy lifting in the script is done by GetBoundarySegments with the applicable SpatialElementBoundaryOption set.

Fairly straight forward but a little tough to find guidance on mechanics to set the applicable SpatialElementBoundaryOption.
