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 objects 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 documents
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 documents 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.
