Description
** Internal Publish Only! This article may contain information that is not intended for external circulation. **
Strange lines radiate to the upper left corner, and to the bottom of the ArcMap draw window, when data is symbolized with a double line symbol.
![[O-Image] Example of radiating lines](https://webapps-cdn.esri.com/CDN/support-site/technical-articles-images/000009386/00N39000003LL24-0EM39000000wd1o.png)
Cause
The display problem is caused by intersection errors in the data.
Solution or Workaround
- For ArcInfo coverages, change the FUZZY tolerance to a lower value. For example,
Arc: tolerance <coverage_name> fuzzy .001
OR
Import the coverage line features to a file geodatabase. - For CAD data, import the polyline feature class from the CAD file to a file geodatabase.
