API Reference > geometry-core > Curve > LineString3d > addMappedStrokesToLineString3D addMappedStrokesToLineString3D Method evaluate strokes at fractions indicated in a StrokeCountMap. The map must have an array of component counts corresponding to the segment of this linestring. "fractions" in the output are mapped within a0,a1 of the map.componentData addMappedStrokesToLineString3D(map: StrokeCountMap, destLinestring: LineString3d): number Parameter Type Description map StrokeCountMap = stroke count data. destLinestring LineString3d = receiver linestring. Returns - number number of strokes added. 0 if map.componentData does not match the linestring Defined in core/geometry/src/curve/LineString3d.ts Line 1215 Last Updated: 13 June, 2024
