?Not able to change parameters when in Family Editor

Hello new visitor!. Please subscribe to my RSS feed or sign up by email to receive updates on the latest posts.

This happenend to us when changing parameters in the Family Types dialogue.

  • not able to change a Revit parameter from Type to Instance (or otherwise)
  • not able to change a value of a Revit parameter eg width = 600 to width = 400

History

We changed the "UniformatClassifications.txt" to our own classification.
We developed our own Revit library and added directly the Assembly code in it for all objects.

Problem occurs when

  • Re-install of Revit and forgot to change the "UniformatClassifications.txt" file, OR
  • Use of other Revit objects referencing the wrong assembly code, OR
  • Use of another Revit project specific "UniformatClassifications.txt" file

Solution


Select the Assembly Code in the Family Types dialogue and
- delete the value
- change the value by pressing on the ... button to a good Assembly code
