Error: Error drawing event lines
When executing the EVENTLINES LAYER command to display line events, the command returns the error:
Error drawing event lines
The event table contains zero length events where the FROM_ITEM measure value is equal to the TO_ITEM measure value.
Solution or Workaround
Query the event table to find line events where FROM_ITEM = TO_ITEM.
Zero length event records can then either be deleted or edited so that the FROM_ITEM and TO_ITEM measure values are not the same.
