Using the Router-CIM Post Processor

Post processing occurs after all the elements and text information in the AutoCAD drawing have been described and Router-CIM has ordered and sequenced these elements.  Post processing is the last thing done in the development of NC code.

Post processing is the byproduct of the Sequence command that converts an AutoCAD .DXF file into NC code.  The required .$PP file is provided so that the translation of AutoCAD data to NC code is done without regard to necessary rules and format.

The postprocessor communicates with AutoCAD via the AutoCAD .DXF file.  This file represents the current drawing data in an AutoCAD session at the time an AutoCAD DXFOUT command is given.  In order for the postprocessor to translate AutoCAD drawing data, a .DXF file must exist.

As a user, these commands are transparent to you, and happen fairly quickly once the Sequence command is given.

If the postprocessor is properly set up, there should be no need for extra editing of the NC Code file once it is created.

There are several methods in Router-CIM for inserting commands into the NC Code file before it is created, and those will be discussed briefly at first and then in more detail later in this reference.
