Hello,

You can delete the file in "__pycache__" folder first.

Or, a trick is to add a special string parameter, not displayed in the palette.
In the code add a line to store in this parameter the current date-time each time the code is executed.
Then, the PythonPart will always be unique and Allplan will not use a previous version stored in the cache.

See attached file for invisible parameter.
You can use the time or any random value.

I just show you how to add an invisible parameter in a PythonPart.
I didn't send you the complete code of a PythonPart. I leave you the joy of creating your own functions...
But if that doesn't suit you, forget about the trick I gave you. It does not matter.

You don't have to put a value in the pyp file.
To assign a value to a parameter, you must to do it in the script in the *.py file.
In "create", you can add something like this (it is a random value between 0 and 360):

build_ele.zUnique.value = random.random() * 360

import random
