Stock on facing

[needleworks]

Hi

hope someone can explain this to me.

i have a part that is 6mm in height. My stock is 6.45. i use a facing tool path that removes .45 making the stock 6mm in height.

I have a pocket that is only meant to remove 2mm but when i run the simulation its removing 2.45mm

Ive tried selecting the top height from the top of the model in the tool path settings but it still removes 2.45mm.

can anyone help?

If I were doing that part, I would make the last setting on the heights tab as "Bottom Height" From > Model Top, and the "Offset" as negative 2mm Not saying that's the correct way to do it, just how I would do it.
