Locked parameter values


When creating a Family and you would like to have a parameter value such as Model or Manufacturer to be the same across all Types, try using the Formula column instead of Value.

Note: When wanting to use text, you will have to put the text inside of quotation marks, e.g. “MODEL”

As an added advantage, using the Formula column will also lock the parameter Value so that it cannot be changed when viewed in a project.
The downside here is that each Type cannot have a different Value.
