Defined as line symbol 520.0. Can be drawn with any tool but bézier mode is preferable.
If the bézier tool is used, care must be taken as dot and gap spacing are dependent on location of nodes and handles. See bézier topic for more information.
The default definition has a gap between dashes of 0.3mm, compared with the ISOM specified 0.25mm. Variation is allowed in the specification, see the Variations in Symbols topic for details.
See minimum dimensions but specifically - shortest dashed line: at least two dashes.
a ruined stone boundary.
Optimising junctions of dashed lines
OCAD v5: - First try adding a node at, or close to, the junction, next try the cut and reverse line tools. If the spacing is still incorrect, cut back and add an extra line at the junction, either with or without gaps.
In OCAD version 7- Use the new dash point node at the junction.
