Hello everybody, My question is quick, is it possible to create a custom parameters category in order to put, for example, all the parameters to be filled in by the user or even parameters automated by Dynamo ? For example, on my screenshot I have “Constraints”, “Structure”, “Ribs”, “Identification data” and “Construction phase” (my Revit is in French). Is it possible to create a “Dynamo” category or a category with the name of my company “123STR” to classify new parameters ? Thanks ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/7/0/70a5e8c8ae270b8e9474fd098314b7094b30e0f2.png) ---

No, its not possible… ---

Okay, is there any explanation for this limitation ? ---

I don’t know exactly… but I am sure, not possible the create a new group or category. Maybe @jacob.small or @solamour can explain. ---

Hello @B_lechat - I assume here you are asking how to create a new parameter field which you can use Dynamo to populate? If so, you can totally do this with **Parameter.CreateProjectParameter** ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/a/1/a162ed6bf487175cfa8fce336f3badc8559d26aa.png) If you are looking to create new Parameter Groups (In the image above, _Select BuiltIn Parameter Group_) then those are not changeable and are built into Revit itself. ---

The explanation is these groups are hard built into Revit and have been for a while. This request has been on the ideas board many times and for many years - ain’t gonna happen I’d say. The OpenBIM/IFC enhusiasts would _kill_ for this feature (as would I). The good news is that pretty much every other platform (existing/developing) has integrated such a feature to enable pset groups to exist in the authored environment visually at least. ---

Hello and thank you for your answer. I am not looking to create a new parameter in a parameter group, but rather a new grouping. Like in your screenshot with “Constraints”, “Text”, “Structural”, “Dimensions”, “Identity Data”, “Phasing”. The idea is to have your own parameter group. ---

Hello @B_lechat - Unfortunately that is not possible as this is set in a static way by Revit, as @GavinNicholls mentioned above.
