Rvt import

I imported the rvt file, but it says “The file could not be imported as valid geometry based on the provided geometry format. Please try to export a different format or contact our support for assistance.”

Hello rang,
thanks for reaching out to us here in the forum.

Also, please look at the CAD upload options and deactivate the improve data on import.

Best regards
