rotobj xdeg ydeg zdeg
This command allows one to make precise rotations of an object during object editing. MGED must be in the "object edit" state for this command to have effect. If "object rotation" is not in effect, MGED will select this option for you and perform the rotation. The object will be rotated "xdeg" about the x-axis, "ydeg" about the y-axis, and "zdeg" about the z-axis. The rotation is "absolute"....the total rotation since the beginning of object editing will be equal to the input values. The rotation is done about the "KEY" point for the object being edited.
