This tab relates to the use of macros (also known as NC subroutines or subprograms).
If you want to use macros to reduce the size of the code created for the pattern, click Use macro calls for each instance in the pattern. This setting requires you to use a post that supports incremental programming or local coordinate systems.
If you are using macros, you can save calculation time by also selecting Reuse toolpaths from first Instance in the pattern. In this situation, toolpaths are only calculated for the first feature and reused for the subsequent features of the pattern.
