You can jog sketch lines in 2D or 3D sketches in part, assembly, and drawing documents. Jog lines are automatically constrained to be parallel or perpedicular to the original sketch line.
You can drag and dimension jog lines.
To jog a sketch line:
In an open
sketch with a line, or in a drawing with a sketched line, click Jog Line 
on the Explode
Sketch toolbar, or click Tools,
Sketch Tools, Jog
Line.
Click a line to begin the jog.
Move the pointer to preview the width and depth of the jog.
In 3D sketches, press Tab
to change the plane of the jog.
Click again to complete the jog.
The Jog Line tool
stays active so you can insert multiple jogs.
