Extracting geometry from solids

Here is a STEP file, I imported into HeeksCNC.

I need the geometry in the XY plane. So I transformed the top face to the XY plane, by right clicking on the top face and choosing "Rotate to Face".

I can then extract the sketch by right clicking on the top face and choosing "Make Sketch from Face".

The sketch has both loops in, so I need to right click on the sketch and choose "Split Sketch" to make it into two sketches.

I can then use these sketches to make pocket and profile operations.
