Maybe you need a special feature, go into Macros_recipes and Code_snippets, Topological_data_scripting, Dialog creation. My macros on Gist.github.

Hey there, I followed this tutorial: < >.

I am wondering though -- what is the math for figuring out how big to make the cut away boxes, where to place them, and at what angle to position them.

Is there a formula to calculate all of that?

What calculations must be computed to accommodate for different size cuts and different size boxes to cut from?

Is there a tool in the Part workbench specifically for this operation, or a macro maybe?

Parametric proposal. Modify the dd object properties.

I was going to attach the sketch to a datum plane, but I don't see the advantage of a datum plane in this instance and prefer to have as few objects in the tree as possible.
