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.
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.
