Object Snap On (F3)

Turns object snaps on or off. Activates the Elements and Graphics tabs.

Select the Object Snap mode check boxes to specify the types of snap points that are available.

Elements

Node

Turns on or off node snap functionality for model elements. For example, GENSEC connection nodes and grid intersections.

Item

Turns on or off endpoint snap functionality for model objects. For example, endpoints of a GENSEC.

Item Mid Point

Turns on or off midpoint snap functionality for model elements. For example, the midpoint of a GENSEC.

P-Point

Turns on or off P-Point snap functionality for model elements. For example, a P-Point on a GENSEC.

P-Line Intersection

Turns on or off P-Line intersection snap functionality.

P-Line End Point

Turns on or off P-Line End snap functionality for model elements. For example, a P-Line end on a GENSEC.

P-Line Mid Point

Turns on or off P-Line midpoint snap functionality for model elements. For example, a P-Line midpoint on a GENSEC.

Laser Data

Turns on or off snapping to laser data.

Graphics

Endpoint

Turns on or off endpoint snap functionality for graphical objects. For example a construction aid.

Midpoint

Turns on or off midpoint snap functionality for graphical objects.

Centre

Turns on or off center point snap functionality for graphical objects. For example, a circular construction aid.

Quadrant

Turns on or off quadrant point snap functionality for graphical objects. For example, points representing quadrants of arced construction aids.

Nearest

Turns on or off nearest snap functionality.

Intersection

Turns on or off intersection point snap functionality for graphical objects.

Extension

Turns on or off extension point snap functionality for graphical objects. The cursor is attracted by virtual extensions of graphical objects.

Perpendicular To

Turns on or off perpendicular to point snap functionality. For example, a GENSEC can be positioned so that the start point direction is perpendicular to the object that it is connected to.

Perpendicular From

Turns on or off perpendicular from point snap functionality for graphical objects. For example, a GENSEC can be positioned so that the end point direction is perpendicular to the object that it is connected to.

Tangent

Turns on or off tangent point snap functionality for graphical objects. For example, points of graphical objects where the line connecting the point and the previous point is tangent to the graphical object.

Parallel

Turns on or off parallel point snap functionality for graphical objects. For example, points on a virtual line parallel to the indicated graphical object.

Surface

Turns on or off surface point snap functionality for graphical objects. For example, the surface of a section or a panel.
