That would be my response to a CGO label question back in May. You could use the cmd.rotate and cmd.translate to position the labels, but it is likely to be somewhat painful. If I'm not mistaken, the rotation will always be about and axis through the origin and so you may need to translate the label into the correct position. Thus if you have your label in an object called 'text', you could do, cmd.rotate(axis='x',angle=20.,object='text') and repeat this with different angles, until you get the orientation correct. Then use: cmd.translate(vector='[1.,2.,3.]',object='text') (using the appropriate vector, of course!) to position the label. Not ideal, but if it is sufficiently important, it can be done!
