Controlling the AutoCAD 2000 Drawing Environment 49 · Display AutoSnap Tooltip.This option controls the display of the AutoSnap tooltip. A tooltip is a text flag that describes which object snap is active. · Display AutoSnap Aperture Box.This option controls the display of the AutoSnap aperture box. The aperture box is a box that appears inside the crosshairs when you select an object snap. When AutoSnap is activated, the AutoSnap markers appear only on objects that cross or lie within the aperture box. · AutoSnap Marker Color.This option allows you to specify the color of the AutoSnap marker to make viewing the AutoSnap Marker easier. AutoSnaps and object snaps are discussed in detail in Chapter 6. AutoTracking Settings The AutoTracking Settings area allows you to control settings that affect the display and behavior of AutoCAD's new Polar Tracking feature. There are three features you can control from this area, described as follows: · Display Polar Tracking Vector.This option turns Polar Tracking on or off. When selected, this feature allows you to draw lines based on predefined angles. These predefined angles, known as Tracking Vectors, cause AutoCAD to snap to the Tracking Vector as you move the cursor during a drawing command. · Display Full-Screen Tracking Vector.This option controls the display of tracking vectors. By selecting this option, AutoCAD displays Tracking Vectors as infinite construction lines, extending through the snap point and the cursor and crossing the width of the screen. By clearing this option, the Tracking Vectors extend as rays from the snap point through the cursor to the edge of the screen.
