Thanks for this. Well done. I have created a separate script that will write the department name into the Mass's Department instance parameter. This way I can isolate this in a Mass element schedule. =) I am more than happy to share with whoever would like it.

Same problem here. The masses are much bigger than the room volume. Using Revit 2022... In any case thanks a lot for sharing your script tutorial

Nice tutorial easy to follow along - but i get 4 errors. I can get the outline of the room but cant create the mass or generic the colorscheme. first error is List.GroupByKey "number of items does not match number of keys". Second error under 9. Generat Color from colorscheme "List.IndenxOf" object reference not set to instance of an object. Third error "OverrideGraphicSettings.ByProperties" expects argument type(s) DS Color, DS Core Color etc. and the fourth error "Element.OverrideInView" Dereferencing a non-pointer. Any thoughts on what i might be doing wrong ? thank you :)

Hi O°RI! Thank you for this very useful video and script! Can i check if its possible for the rooms to be extracted based on centreline of the walls before generating the 3D masses? Would also wish to achieve populating the parameter values of those masses by exporting parameters to Excel from Revit via Dynamo and repopulating back to Revit for updating of Parameters. Based on the assumption that the Shared/Project Parameters would have been created in Revit in the first place, the mass family category would have the required parameters ready for data value population. Would you have a similar script of sorts? Thank you!

Hi O°R, I used to have the same problem like a lot of people had with my masses being a lot bigger then my rooms. I fixed this by removing the ''Element.GetParameterValueByName'' node and using the ''Room.Name'' node instead. Hopefully this works for more people as well. I do run into another issue.. When making the 3d masses, I would only like to make then in my Revit project. Now it also makes the 3D masses in Dynamo which slows down the process a lot because making the masses in Dynamo takes up a lot of time. Have you got a quick fix for this? Thanks!!

Hi! i tried following your steps using the Revit 2022 Version, however the override process didnt work, the color wont show up in the project.

Great work. My build of R23 is freezing at FamilyType.ByGeometry using Mass.rft. I am using the OOTB version of the node. It works ok with Generic Model Adaptive.rft, but you will not get the benefits of a mass. Any ideas why dynamo may freeze with Mass.rvt. ? All list lengths are the same...

Hi O°RI! Thank you for this useful script! I have a problem when generating the geometry, the masses created are bigger than the rooms, do you happen to know what's the problem ? thank you !
