How to undo Python script operations?

desert — Mon, 04 Sep 2023 08:22:12 GMT

Hello.

I'm a CGA beginner who has been finding a lot of help by reading the content here.(trial ver.2022.1)

I have a question.

After running a Python script and not being satisfied with the result, I tried to revert it to the original state, but I couldn't find an 'UNDO' feature.

Does Python script have an undo feature?

Any advice will be greatly helpful to me.

Thank you for reading.

Hi,

welcome to the world of procedural modeling with CGA. 🙂

There is unfortunately no undo functionality for Python scripts. If you are unsure about the correctness of a script, it is best practice to save a copy of the scene file (cej) before running the script. Or run the script on a copy of the scene (copying could even be part of the script itself).

Best,
Simon

Having to prepare a copy every time I test a Python script can be inconvenient, but it seems there's no other choice.
I should create Python scripts carefully.
Thank you for your response.
