When I put a datum flag on a dimension it will move after I save the drawing. For example if I have a turned part and I put a datum on the outside diameter to make the center axis of the part the primary datum. When I insert the flag it will be vertical, but when I save the drawing, close it, and then open it again the flag will become horizontal and lie parallel with the dimension line. Ive noticed that this only happens in certain orientations of the datum flag. Does anybody have a workaround for this?
