Tutorial for cross section script

I’m new to blender.
I managed to make a 3D object but I want to make cross-sections at various positions that I would like to print out.
I installed the cross-section script but I can’t get it to work.
Does someone know of a video tutorial that explains this?

Which addon ?

Does the documentation say its works with the version of blender you are using ?

I installed the cross-section script but I can’t get it to work.
Are you going to tell us in what way you cannot get it to work ?

you could use the bisect tool to do some cross sections!

happy bl
