Dimensioning family, can't get reference of a reference plane

[dem1st]

NewLinearDimension method requires ReferenceArray parameter. Reference Planes were successfully created. Now why can't I get Reference of the refplane1 and refplane2 ?

Things worked in this case.

Thanks in advance!

What version of Revit are you working with. I searched for that property in the API docs, and it is not available in current releases. Did you just copy the code from some obsolete source? If so, you need to check what changed in the API since then and perform an appropriate migration of obsolete code:

Yes, apparently it worked eariler and nowadays it turned out to be obsolete. Thanks for pointing to the website and to the importance of using revitapidocs cause it does provide full info on every class's member.
