I’m collecting the rooms from a linked model, then trying to get the room boundaries to find points in rooms. The Crumple Room Boundary node is able to provide the boundaries from linked models, although there seems to be an issue where if the bounding element of a room comes from a linked model the…

The solution I ended up going with: Download the architects models Open these models Reload all of the model links Extract all the boundaries (lines) Fix up any boundaries that don’t form complete polycurves Convert them to a string and export to excel Import the excel to the MEP model Convert fro…

I did try this node and for the same rooms that had issues with room bounding it wouldn’t create the solid.

Do you mean the room calculation point? The elements I’m collecting are all MEP elements, so some categories don’t have that option. I also prefer the element centroid as I find it a bit more ‘stable’ than the element.location node, what are you concerns about the centroid accuracy?

I tried this and did a comparison against the room boundaries, and the room boundaries collected more boundaries for every room than the finish boundary. Although the rooms the finish boundary collected all seem to be ‘complete’ rooms which is better for processing if the rooms are bounded entirely…

[image] RDM: what are you concerns about the centroid accuracy? The edge case of L shaped objects putting centroid in locations which don’t report a useful location is too frequent. The result of which is significant exception handling which slows things down and you still get a lot of false …

I’ll update the script to use the location point, I’ve processed the line based families before so that should be fine. I have seen a few nodes that can take points and rooms, but the internal origin of the linked model is wrong so I’m not sure if these nodes automatically do the transform since I’…

Hi, Instead of working with linked rooms, why not work directly with spaces ? (a process generally applied to MEP models) [image]

Totally agree I could use spaces, but it’s going to take 10-20 times the effort/time to maintain 10,000+ spaces on this project when the architect already has a requirement to deliver bounded rooms so they’ve done that process for me. I’m very hesitant to use any rooms or spaces as the models are a…

Do you have a sample model (not the actual ones but ones which reproduce the conditions) for people to help test on? Stuff like generating the 10,000 spaces (or even 10,000,000 spaces) to do the coordination and then removing them isn’t a big lift.

MEP-Link A.rvt (1.4 MB) I’ve recreated the scenario where the MEP model has Arch-A and Arch-B as model links where the rooms in Arch-A are bounded by Arch-B, I’ll make a simpler version of my script as well for how I had been finding the points in rooms. Arch-Link A.rvt (504 KB) Arch-Link B.rvt (…

@RDM it’s quite a long thread and I’m not exactly sure what the goal is. Seemed to start off with this [image] RDM: Where the outcome of the script is to find what room an element is in but now is more like how to create the rooms (or spaces) in the first place ?? Distilling it down, is t…

The zip file here has a sample graph to generate a playable journal which will run a Dynamo graph on a correctly named .rvt. You can look at how that is structured to generate something which meets your needs.
