Hi All, as the title said, is there any workaround to insert in python script to know in which line my script gone wrong?

may it shown in AP3D command lines when testing with (testacpscript "XXX")?

it keeps giving me "Geometry can not be generated with the given parameters.nil" error

thanks in advance

@bagusvirdo ,

I don't know of any function that could provide this in Python for AutoCAD Plant 3D.
In your case, the default parameters do not match the construction functions.

You can strategically place 'print' commands throughout your code. These will display in the AutoCAD command line. From there, you can determine the last successful 'print' line of code.

print ("if this line shows in the command line, then code is successful to this point")

The Python module is broken in the current version of 2025.

In previous versions of Plant 3D, you could print statements in your code. And if the PlantRegisterCustomScritps command found errors, it would tell you the file and line the registration errored out on.

In the current release of 2025 you will need to use writeLine statements. Create a new text file and write out instead of printing to the console.

Autodesk Development Team is aware of this and said it should be fixed in 2025.1
