Dear Balaji,

Yes, it is.

You can implement a Revit add-in in C# .NET to drive the  RVT to IFC export using the Document.Export method:

Another option is to translate the RVT to Forge and export IFC from there:

In that case, you can work in the cloud and do not need to have Revit installed at all.

Cheers,

Hi Jeremy,

Thanks for your immediate reply. I will check with your provided urls for further process.

Is there any option to open revit files outside vb macro like vb.net application

i.e: User has to open form and select the revit file from file browsing. After file selected, function should open revit file in the background of the application and export to IFC file format.

I searched in the forum and other guide, i got little bit confused with provided sample coding.

Actually i created one vb.net form and given the option to user select revit files and export-button.

I am looking application(form based) oriented process for our requirement.
