I've used this Revit family and associated type catalog in Revit 2018,19,20, however, when trying to load it in Revit 2021 I received a message saying"invalid column type: gallons_us_per_minute" and " could not parse column header:design chilled water flow"
Any solutions?
Hi @IGNACIOB-SGM ,
Unfortunately, this is not the best place to ask such a question.
Please note that this discussion forum is dedicated to programming Revit using the Revit API.
Therefore, you cannot expect an answer to a question such as yours relating to installation, product usage or end user support issues here.
You should try one of the non-API Revit product support discussion forums instead for that:
The people there are much better equipped to answer your question than us.
I hope this clarifies.
Also, have a look at this below link
