I'm unsure which block you are talking about: I see there are two blocks that refer to rot things: in_rot_quaternion_raw and in_rot_from_north_xxx_raw. Looking at the 1st one description, it looks very specific to quaternions to me; the 2nd seems very specific to its own thing, whatever it is.. So I would just add the missing information (unit) in the new block just being introduced, if this is ok for you. Or am I missing some other block in which I could coalesce this new euler thing? > Jonathan > >
