Use Custom Filters

We sometimes don’t want RV RoomLink to update all elements of a selected category. For example, we want to report the rooms/spaces of supply air terminals and not return/exhaust ones.

This is easy since RV RoomLink fully supports using existing view filters in your model to specify exactly which elements to update. To start, create a view filter like below. Give it a meaningful name, so you’ll know which one to select later in the app. You can combine different filter rules and filter sets just like you normally do in Revit. The rule can also target more than one category.

Next, open RV RoomLink’ main window and click Edit on the relevant parameter link:

Enable element filtering, select the filter we created previously, then click OK. If you have a filter that targets multiple categories, just specify it again in other relevant parameter links.

And that’s it! Next time you update Revit parameters with the app, it will only process elements of the selected category that satisfy all conditions in the filter you specified.

Note that the filter needs to exist in the Revit model at the time of running RV RoomLink. If not, you will see a warning message when opening the app.

If you ignore that and run the update anyway, the app may update more elements than required, which can be problematic. Watch out for this behaviour, especially if you plan to reuse the settings from one model in another. The new Revit file needs to have the filters with the same name for the coordinate update to work as expected.

Pro tip: Use these filters in combination with RV RoomLink’s “Distribute Value” feature to set up bespoke parameter linking and distribution! More info here.
