Hi Dima,

Image which your showing is that a section? How many levels do you have?

Can you put your revit file here. It will be better to understand and solve your problem.

Hi ent1g,

Can you show me the picture of your parameter and the error message.

Use “LunchBox” GetParameter Node to get the value of your parameter. Below is an example.

picture of the parameter your looking for.

Can you show me picture.

Are you looking for this.

No problem. Have Fun :)

Hi ent1g,

Try this see if it helps.

Hi Ivan,

Its great idea but unfortunately this is not Revit or Dynamo its done in another software called Tekla structure.

Alexander, Try below steps see if it helps:

Uninstall all the packages. (also from C:UsersUserNameAppDataRoamingDynamo.8packages)
Uninstall Dynamo.
Install Dynamo version 0.8.2 (from http://dynamobim.com/)
After installing dynamo version 0.8.2, Install only package which you need.

Good Luck!

Alexander, i think some of the rooms in your linked file are unplaced that’s the reason your having different counts. I checked the first Python. it is processing all rooms. Try another nodes or methods.

And here how to number of elements in rooms.

HI Artem,

I have the same. No problem tell me what you need I will find out another method.

I look at your file its working from my side. which version dynamo your using?

Alexander, Can you tell me what are you looking for?
