Script to erase components

[ManuMaker_MMK]

Hello community,
I am looking to create a script to remove several components from a STEP file.
My entry point is:
- A STEP file which includes about 2500 components
- A CSV or XML file that includes the list of components that I must keep
The script I want to create will allow me to open my original STEP file, select the components I want to keep, invert the selection and remove the components.

Do you think this type of script is possible with Fusion 360?

Thank you in advance for your answers.

This should be possible. What you'll be deleting are "occurrence" objects. Here's a topic from the help that describes the difference between a component and an occurrence. The other thing you'll need to handle is multiple instances of the same part and multiple levels. For example, you might have a part called "Bolt1" and have 4 instances of that in the top-level of the assembly. This results in the occurrences "Bolt1:1", "Bolt1:2", "Bolt1:3", and "Bolt1:4". If you only want to delete 2 of those 4, how do you identify the specific bolts? I don't know if the naming in the STEP is consistent with the naming once it is translated into Fusion.

Hello Brian,

Thanks for your response.

Your idea is correct about object occurrences. My wish is to use this macro in a semi automatic mode. For all the occurrences that I will have to keep partially, I will not delete them with the script. In a second step, I will manually delete these occurrences.
The script will help me achieve 80% of the task automatically, which will make me progress quickly.
