As one of my first dynamo graphs I chose of course for a fairly simple export/import with an excel file
The aim is to fill in the Specified Return Airflow and Specified supply Airflow from an excel file into the space
A first graph exports some space data to an excel. -> no problems here
The second graph updates space parameters -> here is a problem
When updating the Space parameters Specified Supply/Return Airflow something weird happens with the values.
I suppose it’s because of some conversion somewhere …
The test I performed to try to figure out the solution …
The same value is being added to new shared parameters I added to spaces as well as to the revit parameters Specified Return Airflow and Specified Return Airflow.
Result of this test is that the “new parameters” are correct but the revit parameters are divergent.
Just can’t seem to figure out why oh why oh why???
I’ve been looking into the project units but would not expect this to be the problem.
It appears to me as if there is a slight error on “a conversion somewhere” although I don’t do anything specific to that value before updating in Revit.
Another test I perfomed is a graph that overwrites the value of Specified Return Airflow with the value from the added shared parameter in the space … same difference
Anybody any experience with this situation and even maybe a solution?
Unfortunately as a new user It seems I can’t add any files to this post …
The folder contains the separate files as well as a zip file
