Shared Parameters are invaluable if you intend to schedule any custom parameter values now or in the future from a Project file. Predicting what you may wish to schedule will give you a good idea of how to define the parameters, constraints and labels to give you the data output that you may need. Here is an example of what can be scheduled using SP’s. (Note the Column headings in the schedule can be renamed.)


  • Make sure all content creators in your company are using the identical copy of the Shared Parameters (SP) text file.
  • PITFALL. Making the same Shared Parameter in your own local SP file will not be the same as using the official Office SP file. Essentially parameters that originate from two different SP files are given different data identifiers and therefore Revit® will see them as different from one another, even though they may be identical in every other way. As a result you will end up with duplicate parameters in a Project file that will schedule separate SP data. Unfortunately there is no workaround for this. To solve this problem you will need to swap out the uncertified SP’s (that originated from other SP file) from the affected families and replace those SP’s with the approved SP’s (that are being used in the Project schedule) from the official Office SP file and reload the amended families into the Project file.

Remember to only add specific SP’s into the Project files / Office Template that you wish to schedule (Only tick affected Family categories.)
