Problem: Triangles are drawn at the corner of a dashed line that is offset

Description

For all types of dashed lines that have an offset value, a triangle may be noticeable for 'V' shaped segments. The higher the offset value the more noticeable this effect will be. For most small-scale maps this should not be a problem. However, zooming into one of these areas, or printing at a larger scale may make this more evident.

Cause

This is a known issue in the drawing algorithm used for offset lines. It is only a display issue and does not reflect the actually geometry of the feature.

Solution or Workaround

  • Reducing the amount of offset can minimize or eliminate the effect.
  • The error will be less evident as you zoom out of the area in question.
