Linstyp

Linstyp is a term used in computer-aided design, cartography, and vector graphics to denote the pattern or style with which a line is drawn. In many software packages, linstype refers to the set of dash patterns, gaps, and the overall stroke that defines a line beyond its color and width. Common linstypes include solid (continuous), dashed, dotted, dash-dotted, and centerline patterns. Some systems support more complex patterns defined by repeating sequences of on- and off-segments, as well as phantom or hidden lines.

Implementation and storage: A linstype is typically stored in a library or file and can be assigned to individual elements or to layers. Users may scale the pattern independently of the line geometry using a linetype scale or pattern scale. In CAD, linstype definitions may be loaded from external files (for example .lin in some applications) or embedded in project libraries. In GIS and mapping, line styles may reference symbol catalogs and be adjusted for display or print.

Applications: Architectural and engineering drawings use specific linstypes to convey information (for example, hidden features, centerlines, or break lines). In digital typography and vector illustrations, line types influence stroke patterns and can aid readability at different zoom levels.

Standards and limitations: The availability and interpretation of linstypes vary by software; some systems treat line type as purely cosmetic, while others tie patterns to drawing semantics. Various industry standards may specify preferred line types for certain features, but practice is often software-specific.
