Using gravity snapping

Gravity snapping is the attraction of the pointer to a snap point. Snap points are precise mathematical drawing coordinates. When the pointer approaches a snap point, the gravity source of the snap point is highlighted. The highlighting identifies the snap point as the target that the pointer will snap to. Snap points are also known as "gravity-snapping candidates."

The gravity field of each snap point has a radius of 10 screen  pixels (not document pixels) by default. When the pointer enters a gravity field, a gravity source indicator appears around the point, and the name of the gravity source appears on the screen. You can turn gravity snapping on and off.

Gravity shortcut keys let you activate a single type of gravity snap. By default, gravity shortcut keys are the first letters in the names of gravity-snapping candidates. When you hold down a gravity shortcut key, all other gravity snap points become inactive. For example, if you hold down the M key, only the Midpoint gravity snap point is active.

If the pointer is within the gravity fields of two or more gravity-snapping candidates, the gravity-snapping candidate closest to the pointer has priority. If the gravity-snapping candidates are the same distance from the pointer, the pointer snaps to the gravity-snapping candidate with the higher priority, as listed in the following table.

Gravity-snapping candidate	Description	Gravity source indicator	Gravity shortcut key
Pixel	Point on the pixel grid		S
Node	Node on an object		N
Intersection	Geometric intersection of line segments, arcs, or guidelines		I
Midpoint	Midpoint of line segment		M
Quadrant	Points that are at 0°, 90°, 180°, and 270° on a circle, ellipse, or arc		Q
Tangent	Point on the outside edge of an arc, circle, or ellipse where a line will touch but not intersect the object		T
Perpendicular	Point on the outside edge of a segment where a line will be perpendicular to the object		P
Edge	Point that touches the nearest perpendicular edge (shortest perpendicular distance from the pointer to the edge)		E
Center	Center of the closest object (arc, regular polygon, or curve centroid)		C
Grid	Visible or invisible grid point		G
Text baseline	Point in the baseline of artistic or paragraph text		B
Absolute	Pointer location; temporarily suspends all gravity snaps		A

You can make gravity-snapping candidates active or inactive and set other options to customize snapping.

Corel DESIGNER lets you control how gravity snapping works.

To turn gravity snapping on or off

1 .	Click Tools Gravity.

You can also toggle gravity snapping on and off by pressing Alt + Z.

To use gravity snapping

You can also
Snap an object to another object	Drag an object close to where you want to snap. When the gravity source becomes highlighted, release the mouse button.
Snap to guidelines	Move the pointer to the edge of a guideline or to the intersection of two guidelines. To turn off snapping to guidelines, click Tools Gravity, and disable the Edge mode on the Gravity page of the Options dialog box.

To set gravity options

1 .	Click Tools Gravity.
