If you are a manufacturer working with customers in construction it’s often a requirement to provide product models in a BIM compatible format, commonly a Revit format.
Inventor 2021 gives us the option to work with Revit data and share data to Revit. We can share data directly from the Inventor BIM Content Environment.
When we export we can save out to rfa format, however, there is no option to choose which Revit version we are saving out as.
If your client is using an earlier Revit version this can be a problem.
There is though a method you can follow to set up your system to be able to export out to an earlier version, up to three versions earlier than your current version.
In this blog article, we will provide you with the required setup steps and an iLogic rule that will access this undocumented feature.
Installation Requirements
e.g. copy from Autodesk_Navisworks_Manage_2021_Multilingual_Win_64bit_dlm\x64\NAVMAN\Autodesk\Ldr\IVS\Bin
to
C:\Program Files\Common Files\Autodesk Shared\Revit Interoperability for Inventor 2018\Rx\
iLogic Rule
You will require an iLogic rule to access the custom export functionality.
Create this as an external rule.
Dim oBIMComp As BIMComponent
Dim selectedTemplate As String
Dim targetFile As String
oBIMComp = ThisApplication.ActiveDocument.ComponentDefinition.BIMComponent
Dim templateFileDlg As Inventor.FileDialog = Nothing
InventorVb.Application.CreateFileDialog(tFileDlg)
templateFileDlg.DialogTitle() = "Select Template for Export"
templateFileDlg.Filter = "Revit Family Template (*.rft)|*.rft"
templateFileDlg.InitialDirectory = "C:\ProgramData\Autodesk\RVT 2018\Family Templates\English"
templateFileDlg.CancelError = True
On Error Resume Next
templateFileDlg.ShowOpen()
If Err.Number <> 0 Then
Return
ElseIf templateFileDlg.FileName <> "" Then
selectedTemplate = templateFileDlg.FileName
End If
Dim oNameValueMap As NameValueMap
oNameValueMap = ThisApplication.TransientObjects.CreateNameValueMap
oNameValueMap.Add("CustomRevitFamilyTemplate", selectedTemplate)
oNameValueMap.Add("RevitFileVersion", "Legacy")
Dim oFileDlg As Inventor.FileDialog = Nothing
InventorVb.Application.CreateFileDialog(oFileDlg)
oFileDlg.Filter = "Revit Family Files (*.rfa)|*.rfa"
oFileDlg.InitialDirectory = ThisDoc.Path
oFileDlg.CancelError = True
'On Error Resume Next
oFileDlg.ShowSave()
If Err.Number <> 0 Then
Return
ElseIf oFileDlg.FileName <> "" Then
targetFile = oFileDlg.FileName
End If
oBIMComp.ExportBuildingComponentWithOptions(targetFile, oNameValueMap)
MessageBox.Show("Export to " & targetFile & " finished.", "RFA Export Rule Complete")
There is more to BIM though than just the model itself. If you need to know more about BIM as a manufacturer and what’s required, please get in contact with us by emailing info@symetri.co.uk.

As cyber threats continue to grow more complex, securing how we store, manage, and share data is critical. This month’s bulletin dives deep into three key topics: how to ensure safe file storage and transfers, understanding the risks and benefits of password managers, and identifying the top cyber threats to watch in 2025. Whether you’re a business leader or an everyday user, taking proactive steps now can prevent serious problems down the road.
In this blog post, our Principal Consultant, Enrique Barriuso, takes a closer look at what's new in Autodesk Civil 3D 2026. Building on previous versions, this release brings a range of new features, enhancements, and updates.
Optimising BIM and digital tools in architecture and engineering is revolutionising the industry. By integrating technologies like AI, cloud computing, and data analytics, professionals can enhance collaboration, reduce errors, and streamline workflows. In this blog, we'll explore how leveraging these tools can lead to more efficient and successful project outcomes.
