Specifications

508 Less distinct small path

A less distinct small path or forestry extraction track.

Colour: black.

Line width 0.18mm, major gap 1.0mm.

The remaining parts of the symbol (the dash length and the alternate smaller gap) are not explicitly defined; However the inference is that the sizes should be as symbol 507 with every third dash removed. smaller gap 0.25mm and dash 1.0mm.

ISOM 1990 Definition

As ISOM 2000 but line width was 0.175mm

OCAD Methods

Defined as line symbol 508.0. Can be drawn with any tool but bézier or straight line modes are preferable.

If the bézier tool is used, care must be taken as gap spacing is dependent on location of nodes and handles. See bézier topic for more information.

OCAD default definition

The default definition has a gap between dashes of 0.3mm and 1.0mm, see the comments on the definition above and the Variations in Symbols topic.

Drawing Considerations

Particularly important for the competitor is the classification of smaller paths. Account must be taken not only of the width, but also of how obvious the path is to the runner.

See minimum dimensions but specifically - shortest dashed line: at least two dashes.
