RFA file export options

[Andrii_Humeniuk]

Hi everyone,

I recently found out (link, link) that it’s possible to choose the export version of an RFA file. This feature works perfectly through the user interface, but when using the API, I’m not getting the expected result.

In the sample below, I’m trying to save an RFA file to an earlier version using my custom template. The template is applied successfully, and I get a Mechanical Equipment family as intended. However, the RFA version remains the current one (in my case, 2025).

Dim oInvApp As Inventor.Application  = ThisApplication
Dim oDoc As Document = oInvApp.ActiveDocument
Dim oDef As ComponentDefinition = oDoc.ComponentDefinition
Dim oNameValueMap As NameValueMap = oInvApp.TransientObjects.CreateNameValueMap
oNameValueMap.Add(“CustomRevitFamilyTemplate”,
				"C:\ProgramData\Autodesk\RVT 2024\Family Templates\English\Metric Mechanical Equipment.rft")
oNameValueMap.Add("RevitFileVersion", "Legacy")
Dim oBIM As BIMComponent = oDef.BIMComponent
oBIM.ExportBuildingComponentWithOptions(IO.Path.ChangeExtension(oDoc.FullFileName, ".rfa"), oNameValueMap)

I’d really appreciate any insights or suggestions on how to make the API export to a previous version correctly.

Thanks in advance!

@Andrii_Humeniuk , I did a quick test and I see the same issue as you, in both Inventor 2025 and Inventor 2026 .

I wonder if @chandra.shekar.g or @MjDeck could take a look and tell us if there is a bug or if some change of syntax is needed.

Hi @Andrii_Humeniuk ,

Please try to change below line:

oNameValueMap.Add("RevitFileVersion", "Legacy")

to:

oNameValueMap.Add("RevitVersion", "Revit 2024")

 
Thanks and regards,

Thank you very much @chandra.shekar.g !

I suspected that "Legacy" might not be relevant, so I've been experimenting with it for the last 2 days, choosing from the following: "Revit 2024", "Revit2024", "RVT2024", "RFA2024", "2024", "24" and many others. But I didn't think that the key name might be wrong.

@chandra.shekar.g thank you for this reply.

Would you be able to get the documentation updated for this also?

I could not find any information in the help files that documented this.
Maybe add a sample as well?
