Syntax

void RegenerateTargetLinesAround
(
    int32 HistoryIndex,
    bool bWrapAround,
    bool bGenerateIntersections
)

Remarks

Sets the snapping lines to be based on the history points adjacent to the point with a given history index. The given index can be one beyond the ends of the current history (i.e., -1 or PointHistoryLength) to base the lines on the first/last points. The snap lines will be parallel to the plane axes. Useful for moving a point to be aligned with one of its neighbors.

Parameters

Parameter	Description
HistoryIndex	Index in the range [-1, PointHistoryLength()]. The points adjacent to that index will be used for line generation.
bWrapAround	If true, the first point will be considered adjacent to the last when HistoryIndex is 0 or PointHistoryLength()-1.
bGenerateIntersections	If true, intersections will be generated as higher-priority points. Intersections are performed with generated and user-specified lines that lie in the plane.
