Aids the positioning of objects by placing them relative to the geometry of existing objects.

When object snapping is on, if a point is being specified and it is close to the snap point of an existing object, a symbol displays to indicate that the snap point is present.

In the example, a section is being drawn. The blue symbol indicates that the section endpoint is close to a snap point on an existing object (in this case the end item point of a section, as indicated by a circle containing a cross).

You can define object snap settings and object snap modes.

Project Snaps onto LCS	Specifies if object snaps are projected to the working plane.
Object Snapping	Turns object snaps on or off. Activates the Elements and Graphics parts of the Object Snaps & Pline Filters window.
Projected Start / End	Turns projected snap mode on or off.
Significant Snaps	Turns significant snap mode on or off.
Distance Snap	Turns distance snapping on or off. Enter a default distance.

Select the object snap modes to specify the types of snap points that are available.

Endpoint	Snaps to endpoints of objects.
Midpoint	Snaps to middle points of objects.
Centre	Snaps to centre points (for example, a circular construction aid).
Quadrant	Snaps to points representing quadrants (for example, example, points representing quadrants of arced construction aids).
Nearest	Snaps to the nearest points of objects.
Intersection	Snaps to intersection points of objects and to points where objects intersect (visually), but there is no actual 3D intersection because of different object positions.
Extension	The cursor is attracted by virtual extensions of existing objects or P-Points.
Perpendicular To	Snaps to perpendicular points of objects.
Perpendicular From	Snaps from perpendicular points of objects.
Tangent	Snaps to points of objects where the line connecting the point and the previous point is tangent to the objects.
Parallel	Snaps to points on a virtual line parallel to the indicated objects.
Surface	Snaps to points on the surface of objects.
Surface Intersection	Snaps to surface intersection points of objects.
Node	Snaps to node points of model elements (for example, GENSEC connection nodes and grid intersections).
Item	Snaps to endpoints of model objects (for example, endpoints of a GENSEC).
Item Mid Point	Snaps to middle points of model elements (for example, the middle point of a GENSEC).
P-Point	Snaps to P-Points of model elements (for example, a P-Point on a GENSEC).
Pline Intersection	Snaps to P-Line intersections of model elements.
Pline End Point	Snaps to P-Line endpoints of model objects (for example, a P-Line end on a GENSEC).
Pline Mid Point	Snaps to P-Line middle points of model elements (for example, a P-Line middle point on a GENSEC).
Laser Data	Snap to points on laser data.

Select the required P-line Filters to define the P-line snap points that are visible.

The list of available P-lines is populated with all P-lines filtered by P-line PKEY and Description. The Standard and System P-lines can be expanded or collapsed.

Visible		Select the check box in the header of the column to select or deselect all P-lines in the list. Select a check box to mark the P-line as visible. Deselect a check box to mark the P-line as not visible.
Remove		Remove the currently selected user-defined P-line from the list of available P-lines.
Reset to default		Returns the P-line Filters to the default settings.
Additional P-lines
	PKEY	Input a PKEY value of four letters in the field to define the PKEY for a user-defined P-line.
	Description	Input a PKEY description in the field to define the description for a user-defined P-line.
	Add	Adds a user-defined P-line to the list of available P-lines.
