PROBLEM

In ArcMap, short hash line symbols do not display on some line segments

Last Published: April 25, 2020

Description

In ArcMap, short hash line symbols sometimes do not display in ArcMap on some line segments.
[O-Image] Short hash line symbols sometimes don

Cause

This is a known caveat for on screen display of very short hash line symbols due to the performance enhancements implemented at ArcGIS Desktop 9.3.

Solution or Workaround



  • Ignore the on screen anomaly, as the symbol displays correctly when printed or exported. For example, this is the same area of the map from the map exported to PDF:
    [O-Image] Same area of the map from the map exported to PDF
  • In this example, the hash line symbol has 1pt width and 1pt length. This symbol is indiscernible from a round or circle character marker symbol that is 1pt, so a different symbol should be used instead.
