Hi Jeff, so there's a couple of different variations that you can do for making slices.

To start with like Pilou says you'll want to draw a line and then probably use Transfrom > Array > Dir to repeat the line to control where the sections will be at.

Then if you want to cut your objects up into solid slabs, you can use a boolean command to slice the object up by the lines, that looks something like this:






If you want to generate cross section slices as curves, then create that same kind of line pattern, but instead of doing a boolean select the lines and run the Construct > Curve > Project command. That will project the lines onto the objects that you select which will basically trace planar section curves.
