Good morning....
The easiest way would be by establishing a tool catalogue., in which all tools are added that are necessary. Of course that catalogues is editable at any stage. You can either embed the catalogues constantly into the MAC file (before InventorCAM 2012) or into the PRP file (from 2012). In that way it is always available if you create a new program. The parameter
tool_table_name = tool catalogue (here the name of your own catalogue is used) is responsible for the allocation.
That was it. If you have any more questions don’t hesitate.
