RevitLookup is a free, open-source add-in for Revit, which you can use to explore the Revit API.

You will find it invaluable for working out which Revit element properties you can use in PropertyWizard.

In this post, I am going to explain how to download and install RevitLookup, and then in future posts I’ll explain how to use it with PropertyWizard.

How to download RevitLookup

The quickest way to get RevitLookup is to download and run this installer from GitHub:

Just click on the image to go to the GitHub installer page, and then click the Download button (highlighted in yellow in the image) to start the download.

Once you have downloaded the installer, you can Open or Run it. It’s a pretty straightforward installation – there’s no complex configuration to do! When you restart Revit, you should find the Revit Lookup button on the Add-Ins tab of the ribbon:

Other ways to install RevitLookup

Since RevitLookup is open-source, you can download the source code from GitHub and compile it yourself.

There are also compiled builds available at Lookup Builds. These don’t come with an installer, so you have to install them manually.

You’ll want to download the latest build for each version of Revit that you want to run Revit Lookup in.

Each build is stored as a compressed 7zip file, so you will need a copy of 7zip to unpack them.

Within each build package there are two files:

  • RevitLookup.dll, which is the compiled code of the add-in
  • RevitLookup.addin file, which is the ‘manifest’ file for the add-in

To install the files, place the .dll and .addin for each Revit version in the relevant Addins folder on your computer:
