Can the RunCode Function be used to filter for any specific Expression in the code?
I am looking for a way to handle G01 and G03 in a Gcode.

In your Machining project at "Program Events" You can setup the program to trigger specific actions based on M Code. 

   

By default it will be a program call but you can change this to RunCode by adding "Code:" before the expression or by clicking the green plus sign.

   

G01 and G03 will be converted to linear and circular movements, if you want an extra action after it you must specify it as an extra command or use one of the program events available (Path start, Path Approach, etc...)
