I'm using the flat operation to face my part because I cannot use the face operation because I require some containment and that option isn't available in the 2D face operation. I'm creating a mold with large cavities that take up most of my stock but I'd like to machine over them nonetheless. The flat operation sees this as unnecessary and so I must select the "machine over holes" options. The problem however is that it does not create a valid continuous toolpath no matter how large I set the limit for "machine over holes, even if the limit is greater than the size of my entire stock.
What I would like to do is to face the top of my part, with the exception of the 2 holes highlighted here, with tool containment inside boundary and I am unable to do that with the face operation because it doesn't provide the option for containment boundaries and the flat toolpath is glitching due to the cavity.
A very tedious and unnecessary workaround has been creating another piece of stock WITHOUT the cavities (but with geometry to select the holes I wish to avoid machining) and creating a new manufacturing setup.In that case the flat operation gives me the desireable toolpath.
