Adding a Jog
You can add jogs to linear (standard and ordinate) and angular dimension witness lines, note leaders, and symbol leaders using Insert > Jog.
When creating standard dimensions, you can add a jog to a dimension using the Jog Line menu:
• No Jogs—Creates an ordinate dimension with no jog line.
• One Jog—Creates an ordinate dimension with one jog line. Select One Jog before picking the dimension for modification.
