What version of Mastercam?

[Javy]

Version 9.1

Should be .3 deep

draw your radius to the depth you require. just half the arc then surface rotate. you now have a surface you can machine. Has to be drawn from side or front.

Sorry, but I need more detailed help

Draw a circle in the side or front plane. Make it's radius the one you need. You then would put a line .3 from the bottom of the circle. You draw a line snapping to the tangent at the bottom of the circle, then use xform|offset to move the line up .3

Trim the circle to that line, leaving the portion you need. Create|Surface|Revolve would let you spin this profile into a surface, which you can then pick for surfacing toolpaths.
