Making a slightly complex section or section

Hello

I would like to make a somewhat complex section or section of a crankcase in CATIA. I'll leave you a picture to show you what I'd like to achieve.

Apparently, there are two casings on which you have to make a section or cut. On one, the section is more complex.

On the other hand, I would like you to remind me of the basics about cuts and sections in CATIA because it's been a very long time since I've used these functions.

In addition, this section or cut should be activated or not on demand. In other words, I would like to be able to easily restore my crankcase to its original state if necessary.

If the information is a little too scarce, I will send additional views.

P.S: the image is from a solidworks model.

Thank you in advance for your help.
