Interactive Revit BIM database exploration tool to view and navigate element properties and relationships.

Please refer to The Building Coder for more information.

The most up-to-date version provided here is for Revit 2022.

If you are interested in an earlier release of Revit, please grab the latest appropriate one from the release list, e.g.:

• latest release for Revit 2022
• 2021.0.0.13 for Revit 2021
• 2020.0.0.4 for Revit 2020
• 2019.0.0.13 for Revit 2019
• 2018.0.0.8 for Revit 2018
• 2017.0.0.24 for Revit 2017
• 2016.0.0.13 for Revit 2016
• 2015.0.0.8 for Revit 2015

Build Informed GmbH very kindly set up a public CI for RevitLookup at lookupbuilds.com using gitlab.com. The output is dual-signed with the Build Informed certificate, zipped and published to an Amazon S3 bucket. For more information, please refer to the Revit API discussion forum thread on CI for RevitLookup.

You install RevitLookup just like any other Revit add-in, by copying the add-in manifest and the assembly DLL to the Revit Add-Ins folder.

If you specify the full DLL pathname in the add-in manifest, it can also be located elsewhere.

For more information on installing Revit add-ins in general, please refer to the Revit API getting started material.

Harry Mattison of Boost your BIM very kindly provided a ready-built RevitLookup 2018 installer:

If you don’t want to deal with source code and just want to use the tool, here is Revit Lookup 2018.msi, an installer for the compiled and signed DLL ready, courtesy of Boost Your BIM.

Harry's installer was cleaned up by @VBScab and submitted to this repository in issue #51 – the MSI in the project is flawed. Here is the cleaned-up RevitLookup 2018.0.0.0 installer. However, please note that other, more recent builds exist for Revit 2018. As explained above, they can be downloaded sans installer from lookupbuilds.com.

Harry shared a new installer in his post on RevitLookup for Revit 2020, which I also added to the installer folder in RevitLookup2017-2020.msi. Says he:

I’ve added some conditional compilation and multiple configurations so that the single solution can be used to build against any version of Revit 2017-2020.

Download the last version of the RevitLookup.

Luiz Henrique @ricaun Cassettari created the RevitLookup.Installation project, a simple installation using Inno Setup to extract the files to the ApplicationPlugins folder.

It generates a digitally signed version of RevitLookup and supports the Revit releases 2017, 2018, 2019, 2020, 2021 and 2022.

This clarification was prompted by the issue #35 – RevitLookup doesn't snoop all members:

Question: I tried snooping a selected Structural Rebar element in the active view and found not all of the Rebar class members showed up in the Snoop Objects window. One of many members that weren't there: Rebar.GetFullGeometryForView method.

Is this the expected behaviour? I was thinking I could get all object members just with RevitLookup and without the Revit API help file RevitAPI.chm.

Answer: RevitLookup cannot report all properties and methods on all elements.

For instance, in the case of GetFullGeometryForView, a view input argument is required. How is RevitLookup supposed to be able to guess what view you are interested in?

For methods requiring dynamic input that cannot be automatically determined, you will have to make use of more intimate interactive database exploration tools, e.g. RevitPythonShell.
