Snap

Contains controls that are used to determine how tentative points snap to elements.

Snap Lock

If on, tentative points are forced to snap to nearby elements.

Snap Lock is automatically turned on when Association (Lock) (see Association (Lock)) is turned on.

(Snap) Mode

Sets the manner in which tentative points can be snapped to elements or used to constrain elements.

Snap Mode	Tentative Points Snap To
Nearest	The closest points on elements.
Keypoint	Pre-defined keypoints on elements.
Midpoint	The midpoints of elements and segments of elements.
Center	The centers and centroids of elements.
Origin	The origins of cells.
Bisector	The midpoints of entire elements.
Intersection	Intersect another element with the point of intersection at its starting or ending point.
Tangent	Be tangent to another element.
Perpendicular	Be perpendicular to another element.
Parallel	Be parallel to another element.
Point Through	Pass through a particular point on the design plane.
Point on	Constrains an element to begin or end on an element in the design file.
Multisnap1, Multisnap2, Multisnap3	Multiple snap modes

Snap Lock must be on for Snap Mode to take effect.

(Snap) Divisor

The number of keypoints on a line, line string segment, or curve segment is one greater than this value.


Element keypoints (when snap Divisor is set to 1).

Snap Divisor	Keypoints are
1	Endpoints of line or segment.
2 (or any even value)	Endpoints and midpoint of line or segment.

Key-in: ACTIVE KEYPNT [value]

Key-in: KY = [value]

Association (Lock)

If on, an association point is created each time an element is snapped to with one of the following:

Dimensioning tools
Place Multi-line
Place Active Cell, with Use Shared Cells on

Key-in: LOCK ASSOCIATION [OFF | ON | TOGGLE]

Dimensions, multi-lines, and shared cells placed with association points are associative; they are automatically modified when the associated element(s) are modified.

Snap Lock must be on for an association point to be created; turning Association Lock on automatically turns on Snap Lock.

ACS Plane (Snap Lock)

(3D only) If on, and AccuDraw is active, the first snap point is forced to lie on the Active ACS's xy plane (z=0). Further snap points then are controlled by AccuDraw's settings. Using AccuDraw's Sticky Z setting, you can force all further snap points to remain at the same Z level (Sticky Z on) or you can “float” in the Z direction (Sticky Z off).

If on, and AccuDraw is not active, all snap points are forced to lie on the Active ACS's xy plane (z=0).

Key-in: LOCK SNAP ACS [OFF | ON | TOGGLE]

ACS Plane Snap Lock was called Construction Plane Snap Lock in versions of MicroStation prior to Version 4.0.

Depth Lock

(3D only) If on, each tentative point is projected along the view z-axis at the Active Depth.

Key-in: LOCK DEPTH [OFF | ON | TOGGLE]
