Apart from this modifier, a lot has been added or marked as deprecated in newer revisions, so this would be good to be able to generate Gerber files fully compliant to the latest revision, but keeping the optional possibility of using an older revision just to be safe. As I suggested, you may add some kind of user option to generate older or newer Gerber to be more flexible. 2001 BURN 100 MORE FAT CONTROL FOOD CRAVINGS > BURN 350 MORE CALORIES > ULTIMATE ENERGY. For Gerber generators, I suggest still omitting this modifier for now (especially if you don't use rotation) to ensure maximum compatibility with all current CAM software. 1Q Q A Henry Gerber forms the / L i Society for Human Rights.

According to the revision history, 'The mistakenly omitted rotation parameter of the circle macro primitive was restored.' in revision 2015.06 of the spec. This is what I did to ensure the Gerber files were correctly formed. on CASSIOPEIA E-11 mobile devices using the CASIOs Digital Camera Viewer software. GC-Prevue, GC-PrevuePlus, GC-CAM Edit, GC-PowerStation, GC-PowerPlace. Since there was no clear concept (as far as I remember anyway) of optional modifiers in earlier revisions of the spec, many CAM software developers probably have assumed the number of modifiers was fixed for each primitive. It stores a compiled set of Gerber files saved by CAM350 software.

Yes, although not strictly necessary as rotating a circle is just a matter of rotating its center, they probably added it to make all the primitives have a rotation parameter, for consistency but it's still optional for the circle, whereas it's not stated as optional for the other primitives (probably for backward compatibility).
