Choose the IntelliSketch command 
located on the Home tab→IntelliSketch group or the Sketching tab →IntelliSketch group.
On the Relationships page of the IntelliSketch dialog box, select the relationship options that you want IntelliSketch to recognize as you draw.
(Optional) On the Cursor page of the IntelliSketch dialog box, select options for cursor size, locate zone, and intent zone.
Choose a drawing command.
Move the cursor around on the drawing sheet to find IntelliSketch relationships.
Click when IntelliSketch recognizes a relationship you want to use for the element you are drawing. When you click with an IntelliSketch relationship indicator displayed at the cursor, the relationship is established in the drawing.
Tip:
IntelliSketch places relationship handles as you draw. These relationships are maintained when you modify the drawing.
To add dimensions automatically as you draw, see the Help topic, Dimension with IntelliSketch.
