The tricky bit is, the MLCad spec is the only place I can find the expected output of any ROTSTEP commands; LPub3D's documentation seems to mention only that they support it.
I did some checking and REL seems to be ok afterall, as the result is the same in MLCAD and LPUB.
I'm unsure about ADD though, as LPUB seems to do the same as with REL and MLCAD's step preview is empty no matter the value.
So I'm leaving the implementation unchanged for now.
