Using Smart Mouse for precise alignment
Smart Mouse is a drawing aid that can help the cursor precisely snap to a point on another object
when you are drawing. Snap constraints like Smart Mouse are particularly useful when creating
technical illustrations or documents in which micron-precision is paramount since it can snap the
pointer to the corners, edges, and other points of objects.
Turn off Snap To Grid by choosing Layout | Snap To | Grid. If there is no checkmark, the
option is already turned off. If Snap To Grid is on, the pointer will snap to the grid and not to
active Smart Mouse constraints.
To open the Smart Mouse palette:
Choose Layout | Smart Mouse or Window | Palettes | Smart Mouse.
Types of Smart Mouse constraints
The Smart Mouse tool has 14 types of constraints for your use. The constraints make the pointer (and
objects that you draw or drag) snap to corners or centers of objects, even divisions (such as the
midpoints) of object fractions, specified lengths or angles, horizontal, vertical, or diagonal
movement, tangential or perpendicular alignment with objects, or edges of vector objects.
Relative constraints: Indicate the relationship between the beginning position and current
position when you draw or drag an object. These constraints can display indicators to
indicate a constraint is met. The relative constraints are: Horizontal, Vertical, Diagonal,
Angle, Multiple Angle, Length, Parallel, and Tangential & Perpendicular.
Absolute constraints: Indicate the relationship between the pointer and objects. These
constraints (except Object Edges) can display indicators to show a constraint is met. The
absolute constraints are: Object Corners, Object Fractions, Polygon & Bézier Anchors,
Polygon Fractions, and Object Edges.
