You should look for a Gcode generator program (ie. Mastercam, Smartcam, etc). You can find some Linux Gcode generator programs. Most are windows based. Does your CAD software have a manufacturing package? I would explore that first. You will use the output of the Gcode generator program in EMC2. >> > Linux really isn't the issue.

It is widely used for export and import of 2D and 3D graphics definitions. STEP is another standard used for geometry exchange. STEP is newer than IGES. There is data loss and/or corruption in any and all data converters but most will allow the manufacture of good parts. Data for use in EMC2 (or other control) can be derived from IGES data. The data must be converted into a form usable by the Gcode generator program (of your choice). The IGES data is imported into the Gcode generator program through the IGES converter (usually supplied by the authors of the Gcode generator program). Then the NC programmer can use the Gcode generator program to output a program usable by EMC2 (or other control). There are many Gcode generator programs including some attempts to go direct from IGES/STEP to Gcode. The path is ever changing and evolving.
