Hi,

Is there  any way or API function available to get the formula of Parameters in a Revit family ?

Thanks & Regards,

Hi,

FamilyParameter.Formula ?

Is there an example of how to use this? 

I've been searching all over the web and this is the only instance I can find of the function FamilyParameter.Formula, and with that I can not find an example of how to use it and have been unsuccessful on using it in my own code.

I know this is a very old post, so hopefully you can assist me with this still.

Hi,

I would think you write the same string as using the GUI.

Hi,

This property seems to be gone in the latest version (2021) of the Revit API. Do you know how to retrieve a parameter's formula? or, at least, to retrieve if a parameter has a formula or not?

Best regards,

Jonathan

Hi,

I have the same question for Parameter and not FamilyParamter. How to retrieve the parameter's formula or at least to know if parameter has a formula or not ?

Best regards,
