Description of situation or difficulty:
milling everything down to a certain level and no farther
The solution was:
This one isn't fresh in my mind, but here goes: at first, I was trying to use custom cuts. Custom cuts is necessary if you want to save time and machine exactly to a given plane, such as may exist in the part. Particularly in roughing, you need to make use of custom cuts to ensure that you don't leave a heavy stock above a certain plateau that may exist between your depth of cut options.
But custom cuts does not limit the downward toolpath creation. In this one situation, I needed to go back in and just alter the upward cusps of a mold project. What you need to do in this situation is sketch out a rectangular plane and surface it. Translate it right into your model to the level that you want to cut down to. I'm a bit hazy from here on, but I think you select your model to create toolpaths as per usual, and then select this planar surface as the boundary. Nothing will be re-cut below it.
