At present, “Z Top Offset” is the only way to control how a part is located relative to the top of the defined stock. I’m proposing replacing that with a “Z anchor” which would be one of: top, middle, bottom.
The reason for this is that I want to make double-sided part milling a lot easier. And the best way to do that is to locate the part in the middle of the stock. Currently that requires you to know the stock and part size and do a manual calculation. This is error prone.
The only reason I can think not to do this is if using “Z Top Offset” is common for other scenarios. And maybe understanding those scenarios, I can come up with a better UI treatment and other options.
