ReadonlydashSigned dash lengths in drawing units (not millimeters; apply
model_units_to_millimeters_factor when mm are required): positive = ink,
negative = gap, zero = dot. This is a zero-copy subarray view into the
underlying T8LDData.linetypes.dashes buffer — do not mutate.
ReadonlypatternPrecomputed ∑|dashes| per-cycle length in drawing units (not millimeters;
apply model_units_to_millimeters_factor when mm are required).
ReadonlyscalePer-polyline CELTSCALE × LTSCALE multiplier applied to dashPattern at render time.
Dashed-line descriptor attached to a polyline style when the polyline references a non-CONTINUOUS linetype. Absent (
undefined) for solid polylines.Rendering of dashed lines is not implemented in
@twinfinity/coreas of this release; consumers building their own renderers can use this field.
