Why Override by Param exists
Colouring a model by a parameter is one of those things Revit can do and makes you work for. View filters are the right mechanism, but creating one per value, assigning a colour to each, and adding them all to the view is a lot of dialog work for something you want to look at for five minutes and then reverse.
How Override by Param works
Pick a category and the parameter you want to colour by - the parameter list is built from the elements actually present.
Choose a mode: colour the values, hide them, isolate them, run a QA check for missing values, or colour by numeric range.
Pick a palette and a transparency, and the legend builds itself with a swatch, the value, the element count and the percentage of the set. Four quick presets cover the schemes people reach for most - rooms by department, rooms by name, walls by type, doors by fire rating.
Click a legend row to select and zoom to those elements in the model.
Apply, and the overrides are created as real view filters rather than temporary per-element overrides. By default it also clears any existing per-element overrides on that category in the view first, because element overrides win over filters and would mask the colours - there is a toggle to keep them instead. Each apply is one undo entry.
Export the coloured view to a 300 DPI PNG when it needs to go into a meeting pack rather than stay in Revit.
Before
A colour-by-parameter study means building view filters by hand, one per value.
After
You pick a category and a parameter, look at the legend with its counts, and apply.
When to reach for it
- Checking that a parameter has been filled in consistently across a category.
- Producing a coloured analysis view for a coordination meeting.
- Isolating everything with a particular value to work on it.
What it does not do
- It works on the active view - unless that view's filters are controlled by a view template, in which case the filters are written to the template and every view using it changes too. Worth knowing before you run it on a production sheet view.
- The overrides are view filters, so they behave like view filters - including appearing in the view's filter list afterwards.
- The parameter list is read from the elements in the view and capped at two hundred names, so on a very parameter-heavy model a rare parameter can fall off the end of the list.
- Hide and Isolate work on the values that exist; the blank group is not selectable in those two modes today. The QA mode is what finds the blanks.
- Two hundred distinct values means two hundred filters, which Revit notices. There is no progress indicator, and five thousand elements can block for several seconds.
- On a workshared model a view owned by another user fails with a Revit error rather than an ownership message, and the run rolls back.
Questions
- How do I colour elements by a parameter value in Revit?
- Through view filters, one per value, each with its own override - which is correct and tedious. This builds them from a category and a parameter in one step, with the colours assigned and the legend showing element counts.
- Can I hide or isolate by parameter instead of colouring?
- Yes, both are modes alongside colouring, plus a QA mode for finding missing values and a range mode for numeric parameters.
- Are the overrides permanent?
- They are applied as view filters, so they persist on the view like any filter. Remove them through the view's filter settings, or use the Clear button - which deletes every filter this tool created, across every view in the project, not just the one you are looking at.
