MC9 Surface contour problems

[kojack]

I find myself drawing containment boundries with rectangles or circles

I machine alot of thin wall cavity's that dont have wire frames

is there a easier way to control wich side of the drive surface the tool paths

are layed down ...

Thanks again

Allot of time you need it create boundary's as it will see both side of the surfaces. allot of the time it is how you pick the surface to use. if there is a surface at the top between the wall include this surface and and mastercam will not go to the other side of the same surface being not the normal of that surface.
now are all these pockets basic and would be better cut as a 2D? so make edge curves a cut from there.

I wish you could show me sample file. this would give me an option for few thoughts.

Kojack ,
I will create my own boundries and when I pick surfaces or solids I will pick all because I know where the tool will go if you leave to much room the cutter will try to sneak in and cut what you do not needI will also create my boundries in the air above or below my part. this makes it much easier to chain.
