Edit Dimension > Number Rotation (Annotate Menu)

This command can be used to alter the rotation of an existing dimension text.

Any measurement object can be identified.

The dimension text direction can be entered using the mouse, by clicking anywhere in the drawing. The location of this position relative to the dimension text position determines the dimension text's rotation angle.

After entering the new dimension text position, the measurement object is rotated accordingly. The dimension text mode is set to "Rotated".
