Problem in exporting model in .dae format.

[Anonymous]

Hi,

When i try to export my 3d model in revit 2020 software it is giving me an error as 'object reference is not set to an instance of an object error'. Can you please help me with it?

Thanks,

The information you share about the problem is insufficient. I don't think anybody can help you based on that short statement. Are you yourself the programmer of the exporter add-in?

It is probably a problem with your add-in registration.

Here is the documentation for that:
