Actually I've just discovered another workaround that could I suppose be scripted (need to learn how to script!)

Draw a line, then draw another line 90º perpendicular to the first, select that and use the directional array tool, choose the amount of segments, then left-click again at the end of the original line. Then use the trim tool to break out into segments. What palaver! But it does work. A script to do all this, then clean up afterwards would be acceptable, but I'd rather have a script baked into an actual tool! ;0)
