Using Parameter to Control Sheet List Order

To effectively sort the sheet list, I introduce a parameter called "Discipline Order" to the sheet list. Go to Manage tab > click Project Parameters (under Settings Panel).

I will make this parameter a Project Parameter. With the Project Parameter window open, click ADD. Follow the image below to create this parameter. Make sure you check the "Sheet" check box in the Categories scroll down menu.

With the "Discipline Order" parameter created. Open any Sheet and look at the Properties menu. You should see your newly created parameter under Identity Data in the Properties menu. Start entering the appropriate discipline** (i.e. Architecture, Structural, Mechanical, Electrical, Plumbing, etc..) into the sheet properties. We are now ready to use this parameter to sort the sheets.

From your Project Browser, scroll down to Schedules and select the Sheet List. (If you have not created one yet, go to View tab > Schedules (under Create panel) > Sheet List.) From the Sheet Properties, click Fields.

Go to the Sheet List Properties > Fields > Add "Discipline Order" parameter from the "Available Fields" (left) to the "Scheduled Fields" (Right).

To sort the discipline. Click the Sorting/Grouping tab and follow the image below for the settings. What I am doing here is to tell Revit to sort the Sheet List by Discipline Order first, then sort by Sheet Number.

If you need to add Placeholders to the Sheet List, you can as well take advantage of this Discipline Order parameter. Go back to the Sheet List and add the Placeholder Sheet as you normally would. In the discipline Order column, type in the discipline. Once you input the discipline, Revit will automatically move your Placeholder sheets to the correct discipline.

** I would suggest adding a number before the discipline.  For example, 0 – Demolition, 1 – Architecture, 2 – Structural, 3 – Mechanical, 4 – Electrical, 5 – Plumbing… and so forth. This gives you better control on the discipline order.
Since we have already created the Discipline Order parameter, we can take advantage of it to organize the Sheets structure in the Project Browser.
