History enables you to record toolpath revisions.
This page contains the following:
Toolpath Type — Select the type of toolpath. PowerMill automatically selects one option, but you can manually change it if required.
Revision — When you modify a toolpath the revision number is automatically incremented. You can alter this to any value if you want.
History — Displays who has created and modified this toolpath and when. It contains <programmer> created <date (yyyy-mm-dd)> for the creation and <programmer> modified <date (yyyy-mm-dd)> for edited toolpaths.
Notes are stored with the project, allowing you to keep information on the toolpaths for yourself or other users.
You can add any of these fields as comments in the NC program output file by using any of the following variables in the NC Program Commands/Comments dialog:
%[notes] %[description] %[toolpath_type] %[edit_history] %[revision]
