Which version of Dynamo is for which version of Revit?

Dynamo was created in 2013, and just like Revit, it was not backward compatible. It was vital to pay attention to the version in which the Dynamo script was saved. This is why it is highly recommended to add the applicable version of Dynamo to your script name.

See table below. The “x” represents a build number and can be any number. What’s important are the two numbers shown in the table. For example, if you saved a script in Dynamo 2.4.x, it will most likely work in Dynamo 2.5.x because they are both within 2.0 to 2.9 for Revit 2020 to 2021.

Be aware of 2.0 and 2.10+ versions of Dynamo

While in general, scripts saved in Dynamo 2.x will work in Revit versions 2020 and later, there are a small number of nodes that behave differently and therefore need to be saved separately, such as the Export to Excel node. In Dynamo 2.6 the node is called “Data.ExportExcel” and in Dynamo 2.12 the node is called “Data.ExportToExcel”.

In Dynamo 2.6:

In Dynamo 2.12:

Which Dynamo version do I have?

Check which version of Dynamo you have loaded on your computer by going to Help > About (or for version 2022 and later, Dynamo > About).

Where can I find the latest stable builds?

In general, always install the most stable build for the version of Revit you are using. Visit this link below to see all the latest stable builds and the last date modified. Note that for versions Revit 2020 and later, Dynamo is automatically installed when Revit is installed, and will be updated when Revit updates. For Revit 2019 and before, you must download and install separately. At the time of this post, we are probably all working in Revit 2020 and later and won’t have to worry about installing and updating Dynamo anymore. Those grueling days are gone. Many thanks to the Dynamo development team and community.
