Help. ImportError: No module named Application in Civil3D 2021 (2020 works)

In Civil3D 2021, I want to run a script to discard all objectdata. The dynamo script does run in Civil3D 2020 but doesn’t work in 2021. The issue is attached below:

Gets all the DWGs in at the folder path recursively.

Writes a log file of the files that are processed in %temp%\D4C3D.log

@folder: The path to folder containing DWGs
@old_block: the name of the old block in the document
@new_block_path: the path to the new block, the name of the file will be used to name the new BlockTableRecord
@layer: the name of the layer of the new BlockReference

@rotation: the angle in radians to rotate the new BlockReference

Can you post the first 50 lines of code as an image?

See attached

As I suspected, the issue is at line 13, you should bring on the next line clr.AddReference(‘acmgd’)

Thanks a lot Paolo. Issue solved :slight_smile:
