Using Guidelines While the regularity of the reference grid allows you to place points with great precision, some points require more flexibility. Guidelines are lines or circles that you place using techniques similar to those used to draw regular lines or circles. However, guidelines behave like the reference grid-while they are saved as part of the drawing, they are not actual drawing entities and only provide a drawing reference. The appearance of guidelines is controlled on the Appearance page of the View Options dialog box. s Using Gridpoint snap allows you to snap points to the guideline wherever guidelines and grid snap intervals intersect. For more information on setting the grid snap interval, see "Setting Up the Grid" on page 61. s Guidelines are also useful for entering points when Gridpoint snap is off. Just as in Nearest Point snap, simply position the pointer near a guideline and the AutoPoint Indicator identifies points along the guideline, especially near the intersections of guidelines.
