The same runtime errors appears continuously.
I found a solution which is not useful.
Does anyone can give advise to me?
My goal was to make many masses in Revit by using RIR.

Before Solution exception:Starting a new transaction is not permitted. It could be because another transaction already started and has not been completed yet, or the document is in a state in which it cannot start a new transaction (e.g. during failure handling or a read-only mode, which could be either permanent or temporary).
Hi, see here about using the python button to open and close transactions. You need a trigger to avoid multiple transactions happening at once. The trigger would be set to False until you need to initiate the button, and then set back to False after that button has been run.
