PowerMILL 8.0 offers all of the original features of PowerMILL 7.0, but with numerous improvements. The most significant improvements are:

Toolpath preparation

There is a new set of options on the individual Boundary and Pattern context menu, which allows you to undo and redo boundary edits (see "Undoing patterns and boundaries" on page 7).

You can now perform Boolean operations on boundaries (see "Boolean boundaries" on page 8).

There are a few enhancements to Tool Axis (on page 12):

Tilting - when tilting in a Fixed Direction, PowerMILL first searches in the direction specified, and if that fails, searches in the opposite direction.

Automatic Collision Avoidance has two new Tilt Tool Axis options.

There are several Tool enhancements (on page 20):

A new Tool Database (on page 14) button is available on the Tool toolbar.
