2 Choose Layout > Snap To > Smart Mouse to turn on the Smart Mouse. A check mark shows that Smart Mouse is active. Note: Be sure Snap To Grid (in the Layout > Snap To menu) is off when you use the Smart Mouse. If Snap To Grid is on, the pointer will snap to the grid and not to active Smart Mouse constraints. Smart Mouse constraints Identifying multiple constraints Up to two Smart Mouse constraints can be met at the same time. For example, you can drag an object in such a way that it triggers both the horizontal constraint and object corner constraint. Although you can activate several constraints, only two constraints can affect the pointer at once. When this constraint is active Smart Mouse snaps objects and constrains the pointer to Angle A specified angle Diagonal Straight diagonal movement — all multiples of 45º Horizontal Straight horizontal movement— 90º and 270º, or 0º and 180º, depending on the current coordinate system Vertical Straight vertical movement — 0º and 180º, or 90º and 270º, depending on the current coordinate system Length A specified length in points (based on 100% magnification) Multiple Angle All multiples of the specified angle Object Corners The corners of the bounding boxes of vector objects Object Edges Edges of the paths of vector objects (not their bounding boxes); when Object Edges is active, other constraints don’t affect the pointer Object Fractions A specified division of vector objects; for example, specify 1/2 to snap to the center of objects Object Points Any anchor point on the paths of vector objects Object Segments Specified divisions of the segments of vector objects; for example, the pointer snaps to the midpoints of segments if you specify 1/2 Tangent & Perpendicular Movement in a straight line, tangent or perpendicular to vector objects
