How to install RevitLookup

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

RevitLookup is maintained by Jeremy Tammick of Autodesk, on GitHub:

However, GitHub just hosts the source-code for the add-in. To install it in Revit, you need a compiled version. These are available here:

Downloadable builds of RevitLookup

You can see that the top four entries are the latest versions of the add-in for Revit 2016 to 2019.

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


When you restart Revit, you should find the Revit Lookup button on the Add-Ins tab of the ribbon:
