Otools Combine is a tool that empowers you and your team with better and smarter concatenation tool. The tool is perfect for you who want to enrich a model with consistent data. Combine is intended to be utilized when combining several Revit parameters to a new parameter.

A very simple tool that chains different parameters on an object and then compose it on a new parameter. The tool does not create new parameters but utilize what is already created in a project.

Like always, a tool created with a task based configurator, allowing you to reuse setups from project to project. And of course, a rule-based configurator enabling you to sort and differentiate what you need and don’t need.

Instance-, type-, shared-, project-, built-in parameter? The tool support everything you need to combine parameters in Revit.

Getting Started

  1. Open the otools ribbon and click on Combine

  1. Following user interface will appear

Click on “Add” to create a new Task

Click on “Edit” to edit a selected task

Click on “Delete” to delete a selected task

Click on “Save” to save configuration

Click on “Load” to open and load a preconfigured task(s) incl. settings

  1. Select a certain Category or several Categories


  1. Select parameter where the combined value should be generated

  1. Use Filtering options if needed. Filtering options are configured in the blue area:

Filtering enable Revit users to filter and apply combine parameters for items that fulfills configured settings. Example above shows that Ducts Fittings where Family name contains “Round” are only to be affected by this setting. This means that the tools will only combine parameters if these rules are met.

*TEXT* mean: every instance that contains TEXT. For more info please see Other features.

  1. Use the parameter chooser to find wanted parameter that needs to be merged or combined and click twice to move it to the formula area.

Use the up and down arrows to move constant values.

  1. Click on “Save” to save settings
  2. Tickmark the task and click on “Run” to execute

Sample example is shown below:


Other features

Smart filtering options

*sample_text means; every instance that ends with sample_text

sample_text* means every instance that starts with sample_text

* Match any number of unspecified characters;

Can be used to match any number of unspecified characters. For example, “b*k” will match “bench kiosk”, “brick”, and “block”, other example *b*k* will match “bench kiosk”, “bricks” and “blocks” and also “Coarse bricks” and “block 2”.

Host parameters

The tool support hosted parameters, these parameters can be found in the ribbon of Host Parameters, as shown below:

These features can be used for combining hosted parameters to selected categories in the “Category Parameters” ribbon.

Coordinates for structural elements

The categories of Structural Columns and Structural Foundations has built-in functionalities for extracting and combining coordinate values, such as; X-, Y-, Z-values.

Built-in parameters are highlighted in green.
