Which Version of Revit to Use for Development Work on Revit API and Dynamo

[JC_BL]

I need to develop some add-ins for Revit for our draftsmen.  Our draftsmen use many different versions of Revit to prepare drawings for our customers.  The versions can be from 2021 to 2023.  I don't think I need to have that many versions of Revit to be installed in my computer because I don't deal with Revit drawings from our customers.  I "assume" I only need one version of Revit for development work.  Which version of Revit should I install in my computer?

Should I use the latest version?  Just in case a draftsman sent me a copy of his Revit drawing for testing (that can be in any version), I will be able to use the latest version to open the drawing.

Or should I use the oldest version that we use (like 2021)?  I assume the older version will be cheaper to purchase.  I am trying to save some money for the company.

Please let me know what you think.  Thanks in advance.

There are some differences in the APIs across versions. You could run into issues with only having one version to develop on. Look at joining the Autodesk Developer Network. You'll get access to all supported versions for considerably less than purchasing them.

Hi @JC_BL,

Maybe use the Viewer mode of Revit?

About Revit Viewer 

Addins and all other functions work in the Viewer Mode, only actions like Saving, Printing are disabled.

Should be enough for developing/testing addins, depending on type of work addins have to do.

Ps. Check with company Autodesk re-seller if the viewer can legally be used by you're company/country/region.

That is very interesting about using Viewer Mode of Revit for testing.  This may mean I can do most of the development work on my add-in in one version of Revit.  And then use the Viewer Mode of other versions of Revit to test my add-in.

This sounds promising.

Thanks for the suggestion.
