MDTools®
divides cavities into Working and Dead Areas.
MDTools accurately checks to find issues, such as thread eating or connections
outside the port area.
Note
Cavities meeting at the bottom of a flat bottom cavity (cavity with 0 angle in the last step) and an offset hole passing through the flat bottom cavity do not appear in the Meet List of a cavity.
Cavity meeting a Flat Bottom Cavity
When you use flat bottom drills inside cavities, instead of making it exactly flat with a 0-degree angle, use a small angle (for example, 1 degree) and allow the formation of a very small cone at the bottom to get a correct result in design check. (This is a current limitation)
