@shahid.shaikh_C3D can you confirm which version of Civil 3D are you using? you need to click on the question mark and click on the “About”

@shahid.shaikh_C3D thanks, this was an issue that happened with an early version of Civil 3D and Dynamo. I’d recommend you to update to 2020.4 and also update Dynamo for Civil 3D to 2.4.1
