Anchor Sort#

Anchor Sort calculates the starting position within each segment.

ANCHOR MODE#

BASE: The start of the segment, taking Direction and Anchor Offset into account.
REVERSE: The opposite end of the segment.
AXIS: Selects the Anchor at an extreme along the primary AXIS.

MIN/MAX: Selects the minimum or maximum extreme along the CORRECTIONAL AXIS.
AXIS CENTRED: Places the Anchor relative to the common center plane of the selected axis, creating a symmetrical reveal across the segment set. In simple terms, it finds extremes along the primary AXIS and, when there are several, uses their average position along the CORRECTIONAL AXIS.

CENTER: Finds a position relative to the overall center of the set. SEGMENT CENTER defines how each segment center is calculated.

DISTANCE TO OBJECT: Finds the Anchor relative to REF OBJECT. DISTANCE MODE selects the exact method.

DISTANCE MODE

PROJECTION: Projects the reference object’s position onto the geometric direction of the segment.
SAMPLING: Samples the curve and finds a suitable point. SAMPLE COUNT controls the accuracy.
MATRIX: Selects the nearest or farthest of the segment matrices that have already been built.

CIRCLE

Calculates a radial direction from the overall center and selects the Anchor relative to the circular layout.

CIRCLE MODE: AUTO determines the working plane from the majority of segment directions. MANUAL exposes the CORRECTIONAL PLANE parameter.
CORRECTIONAL PLANE: Manually selects XY, YZ, or XZ for CIRCLE mode.
FIX CIRCLE: Toggles additional radial-orientation correction, mainly for segments arranged radially in a 2D plane.
SPLINORA: Uses REF OBJECT as a custom cut position. MIX CLOSED can blend this special cut with the regular closed mode.

MIX CLOSED: Segments that intersect the REF OBJECT cut use SPLINE_TYPE in CLOSE_DUO mode; all other segments use regular CLOSE.

PROPORTIONAL#

When ON, the left and right sides receive factors calculated from the available length around the Anchor. This helps both sides finish growing together. When OFF, an even 0.5 / 0.5 split is used.

ANCHOR SORT MODE#

BASE: Base direction.
HALF: Reverses the direction for the second half of the segment list.

MOD: Alternates the direction by segment index, following the same principle as mod(id; 2).

Note

IMPORTANT: ANCHOR_SORT_MODE BASE, HALF, and MOD use the original segment indices. Reordering and grouping from SEGMENT_SORT are therefore ignored. Support for that behavior may be added later. To reproduce BASE and HALF behavior with custom indexing, use ANCHOR_SORT_MODE MIRROR (see its description).

MIRROR: Only used together with ANCHOR MODE SPLINORA and a connected REF OBJECT. It uses a mirrored direction pattern for symmetrical sets. The example below reproduces the behavior of Segment Sort MIRROR with ANCHOR_SORT_MODE HALF.

AXIS and DIRECTION#

AXIS selects X, Y, or Z for axial and center calculations. DIRECTION changes the selected side or the nearest/farthest interpretation in modes where it applies.

ADVANCED#

CORRECTIONAL AXIS: The secondary axis used to construct the correct orientation. In some cases it may match the primary AXIS.
SEGMENT CENTER: BBOX uses the center of the segment’s bounding box; GEO uses the average position of its samples.
ANCHOR OFFSET: An additional discrete selection or offset within Anchor modes. Do not confuse it with the global MAIN SETTINGS → ANCHOR OFFSET.
