Snap

	Grid Snap	Snap at grid points of the Work Plane.
	Vertex Snap	Snap at vertex of a geometric entity.
	End Snap	Snap at both ends of an Edge.
	Middle Snap	Snap at the mid-point of an Edge.
	Perpendicular Snap	Snap at a point on an Edge, perpendicular to the previous point.
	Center Snap	Snap at the center of a circle or arc.
	Quadrant Snap	Snap at quarterly divided points of a circle or arc.
	Intersection Snap	Snap at the intersecting point of two Edges.
	Node Snap	Snap at Nodes.
	Off All Snaps (Ctrl+X)	Turn off all snaps.
	Lock Snap	Only snapped points will be entered as a valid data entry.

When using some of snap functions, such as End Snap and Middle Snap, the user must select the relevant Edge instead of selecting the actual vertex. Therefore, one must select an Edge which can clearly define the end or middle point.

In GTS, although snap functions are turned on, the user is allowed to select a point other than the snapped points. Lock Snap will block such a point selection at unsnapped position.

The user can control the snap sensitivity by change values of "Selection & Snap Sensitivity" and "Grid Snap Sensitivity" which are located in Environment-View in Main Menu > Tools > Preference. As the value increases, it becomes easier to detect the snap value. However, if the snap sensitivity value is too high, it will blur the snapping accuracy. Therefore, the user should be careful when changing the snap sensitivity.

When too many snap functions are on, it may be difficult to snap at the desired position due to the other snap detections. In such a case, the user must turn off the unnecessary snap functions.
