The parameters with the above types are automatically changed to custom after creation.
Thank you for your note.
Could you please explain a little bit more, please?
Is this a problem for you?
Are you happy with this?
Would you like me to report this to the development team?
Do you think it is unexpected behaviour?
Thank you.
For safety's sake, I passed on your report to the devteam right away to ask them whether this is intentional and expected or not.
The development team replied:
Yes, it's intentional, but I recognise it as a limitation.
A future major release of Revit will offer a better experience.
The reason behind it is that the new data types in this list can be identified by ForgeTypeId but do not map to values in the deprecated UnitType enumeration or the ParameterType enumeration (which will be deprecated in future releases of Revit). You can use these new data types to create parameters in the Revit user interface, but if you try to read the ParameterType value in the API, you'll get Custom. However I believe our customer can use the Definition.GetSpecTypeId() method to distinguish between these Custom parameters.
You are absolutely correct: currently no support for these parameter types.
That support will come in a future major release of Revit.
It is in fact also already available in the current preview release.
