This tool is used to import files that have been created by the Impact Plot tool for use with NC machines such as Lasers and Plotters.
It is very restricted in the type of files that can be read, and should only be used to give a rough idea of what the output will look on the chosen machine. The files that can be read are those that use g-codes and m-codes to control positioning, tool commands etc.
You should first select the file to be imported followed by the Plotter machine / Post-processor Master Tool Setting combination that was used to create the file.
