Edit Dimension > Dimension Orientation (Annotate Menu)

This command can be used to draw alter the direction of an existing measurement. If there is one, the dimension line will be rotated accordingly.

Any measurement object can be identified.

The new dimension line direction is determined by a point which, together with the start point of the dimension defines a straight line in the direction of which the dimension should run. This point can be entered using the mouse, by clicking anywhere in the drawing.

After entering the new dimension line direction the measured object is adapted accordingly; the dimension line direction mode is set to "Any".
