On the Milling side of things I’ve learned that it’s important to know which direction a hole is being milled from.  When we determine mating surface it seems that most holes are milled starting at the mating surface towards non-mating surface side.  However in most cases the CAM programmers are looking at how the part relates to other parts in the assembly to figure out which direction a hole needs to be milled. 

Is there any property in Solidworks on the hole that indicates milling direction of the hole?
