Hallo Petrov

From the screenshot you provide, it seems that you are using Allplan 2021-0-6 or 2021-0-7. We tested from our side we don't have such an issue.

Could you please provide some information from Allplan trace? Normally, if something goes wrong, it will provide some addtional information about the problem. Allplan trace can be opened from Allplan Services. (see attached screenshot)

Apart from that, could you try following to check, if it helps/works?

• run the script directly from Allplan library, or
  
• reload the project or drawing file after save the PythonPart (vs) object
  

sorry I didn't explained it correctly...

After you turn on the trace, if you try to create a PythonPart again from Visual Scripting or directly from library in Allplan. Does it show any additional information? Could you provide some screenshot or just paste the information from trace?

Normally if you choose to show trace and let it write to window, you will get a separate trace window which show some runtime information, after you restart the allplan.

I just tried the script you attached, trace window did show some error (see attached screenshot). We will analyze the problem. Did you get a similar error?

And what kind of error do you have, if you create a PythonPart object via Visual Scripting?

Thanks for providing the screenshot. I've already informed our developer to check this issue. I will reach you back, if there is any solution for solving the problem.
