the object. Click OK to continue. Begin drawing and the object will snap to the reference line. Perpendicular Lets you set a reference line perpendicular to a line or the side of an object. After selecting this option, move the mouse to position the reference line, then click to set it. Begin drawing and the object will snap to the reference line. Tangent Lets you set a reference line tangent to a circle, an oval, or an arc. After selecting this option, move the mouse to position the reference line, then click to set it. Begin drawing and the object will snap to the reference line. Included Snaps an object’s start and end points to the outline of an object or to a line. For example, you can use this option to snap the bounding box of a circle to the inside of a rectangle. Center Snaps the first point you draw to the center of an object or a line. Vanishing Point Snaps the first point of an object to the document’s vanishing point. If you draw with the Line tool, the line will snap to the vanishing point and run to the location of the pointer when you begin dragging. There is one global vanishing point in a document. The vanishing point is used by the commands in the Effects > Perspective submenu as well as the Snap > Vanishing Point command. The default vanish- ing point is at ruler coordinates 0,0. You can use the Effects > Per- spective > Vanishing Point command to apply perspective to selected objects and establish the vanishing point. Using the 1 Side and 2 Sides commands will also affect the location of the document’s van- ishing point. Drawing by numbers Several drawing tools give you the option of entering dimensions to draw objects precisely. This method can be easier than dragging the mouse and watching data in the Status bar to draw objects to precise dimensions. You can enter dimensions when you use the Oval, Arc, Rectangle, Rounded Rectangle, and Line tools. With these tools, you can still drag the mouse to draw interactively. Or, just click in your document. When you click, a dialog box appears. You can enter the width, height, or other values, and then click OK to draw the object. Tip You can draw perspective lines with the Vanishing Point option, and make the lines into alignment guides with the Object > Make Guide com- mand.
