‘ You can export shared parameters to a new shared parameter file if the old parameter file is deleted, or if there are shared parameters in a family or a project that are not in the current shared parameter file.’ Revit Help menu

 SP’s can be exported from any given family into your office SP file.

Export Shared Parameters

  •  It means that you can export shared parameters from content across several offices or countries and begin to salvage and coordinate all these parameters into a single SP file.
  •  Supplied content from Manufacturers or Content creators can use Shared parameters and you can add those parameters easily into Project files and to your office SP file.


I reviewed a project last year where the window and door schedules were scheduling default width, height but all the content had been made using several versions of SP’s to control width, height and depth.

You can guess what happened…..

The schedules were scheduling dimensions that HAD NO RELATIONSHIP to the family geometry in the model!

It was a nightmare to sort out! Concrete slabs were being poured and I was running around trying to fix families. That really did not need to be the case if the families had been made properly and the schedules had been set up carefully in the first place. Try and secure an advanced Revit® drafter in each project, where possible.

Discrepancies in schedules in Revit - BEWARE

Discrepancies in schedules in Revit – BEWARE

Here is an example that shows how the default parameter value ’Height’ could schedule something very different to someone’s SP called ‘My Custom_Height’.  The problem is that default parameters don’t always show as zero if they are not in use, especially if it was originally used, and then changed to SP.

Consider using default parameters where appropriate instead of creating a SP for absolutely everything.
