I recently received an equipment schedule for a commercial kitchen in one of our projects, which appeared to have been created in CAD. Since it’s a pretty wide schedule, the item number column on the left had been duplicated halfway the schedule and to the right, making it easier to read across a row.
I had never seen this before and it sparked my curiosity, since a Revit schedule only allows us to show a parameter once. The trick here is to use calculated values. Hitting the button with the three dots on the right of the Formula field will show you any available parameters to be used in a formula.
I tried this for an array of parameters in a door schedule, and it appears to work for most parameters, but certainly not all. In the example below, it didn't work for the Function parameter, but did work for Finish, Operation and other text parameters.
