Adding Room Numbers onto the Walls as parameter

[Yna_Db]

This will help you to get started with the walls selection:

Parts in Room

I got it from another way… much better! [image] But, pay attention, when you work with parts, there is a “cheating”. if you check EXCLUDED (see red arrow), another ghost part is created. So, I got another nodes to leave only REAL PARTS in the lists. ROOM AND PARTS.dyn -> listing all parts ROOM AND REAL PARTS.dyn -> filtering somethings and filtering ghost parts [image] Room and Parts.dyn (15.8 KB) Room and Real Parts.dyn (32.7 KB)

Getting and setting parameters can be done like so:

Type parameter into element parameter

You can start by trying to get and set parameters and see what happens: See also Element.SetParameterByNameTypeOrInstance and Element.GetParameterValueByNameTypeOrInstance nodes from Rhythm package, as well as what’s exposed in the Dictionary if needed.
