I have rooms as whole apartments in the linked file (e.g. Apartment U203). In the local file I have rooms for each room (e.g. Bedroom, Bathroom, etc.). So local rooms are within the linked file’s rooms. The point of the exercise is to write Apartment Number and Type from the linked file’s rooms i…

RESOLVED: Thank you Nick, I got rid of redundant rooms and it worked. I’ll upload revised graph with warning for anyone who might find a use for this. Linked Rooms Collect Elements.dyf (20.9 KB) ParameterGetFromLinkedRoomHost.dyn (35.2 KB) [ParameterGetFromLinkedRoomHost]

This could be what you need: [image] Getting Room Name & Unbounded Height parameter values from linked Model This should get you started. Definitely download springnodes. The select model elements is to select my linked model. [image]

I’ve done exactly this twice, and a modification of it once (used areas instead of rooms) in the last six months, so I know it’s doable. To get the right help it would really speed things up if you to post the graph you have built, a complete screenshot of the graph, and a pair of sample files to d…

I will post the graph when I’m back in the office. I used it on casework, but when I change the category to Rooms it doesn’t work. It gathers all Rooms from both local and inked file to feed into the node, but null comes out the other side. I had a look at the python script and wonder if Rooms us…

Yna_Db: That method relies on Rooms and Spaces having the same number. Which is exactly what I am trying to get Dynamo to do for me.

I usually shy away from geometry intersections, but room geometry should be pretty safe since they’re all most likely single solids. Just check to see which room geometries intersect with which unit geometries.

I tested my graph on a test project and got it to work. Rooms had data from rooms in linked file added to them. But when I tried it on a real project doesn’t work. Real project has 96 rooms, Test has 36 rooms, so I don’t think it is the amount of data. Real project has rooms in groups (parameters…

[image] Antony_Mcphee: Is it just that Dynamo is flaky? Not about this it isn’t. My guess is that Bakery is not getting the linked rooms correctly. Can you post a screenshot after running t on your project, expanding any errors that pop up as well?

Make sure your rooms aren’t returning any nulls. You could have unplaced rooms or something else. I’ve ran into a few odd problems getting rooms before.

Correct data is being fed into the python script: Elements in local file and rooms from linked file. But nothing comes out from the python script.

Hard to see how you managed the unplaced and redundant rooms. For what it’s worth filtering out rooms who’s area isn’t greater than 0 is a good way to manage this programmatically.
