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

You will find it invaluable if you are using Dynamo or pyRevit, and also if you are using my Revit Add-in, PropertyWizard.

In this post, I am going to explain how to download and install Revit Lookup, and then in future posts I’ll explain how to get started with Revit Lookup, how to use it in Dynamo and pyRevit, and how to use Revit Lookup with PropertyWizard.

Other ways to install Revit Lookup

Since Revit Lookup 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.

The ‘Key’ column shows you which version of Revit the build applies to. 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 three files:

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

To install Revit Lookup, place the three files for each Revit version into the relevant Addins folder on your computer:

C:\ProgramData\Autodesk\Revit\Addins\<RevitVersion>
