In Arc I get a ton of <SPAN style="text-decoration: underline;">Warning 000461</SPAN>: Repaired feature because of non simple and <SPAN style="text-decoration: underline;">Warning 000986</SPAN>: &gt; 25 non simple features. These are errors I'm not seeing in QGIS. What is Arc doing differently, and is it necessary?</P></BODY></HTML> Tue, 21 May 2019 14:47:24 GMT https://community.esri.com/t5/arcgis-pro-questions/differences-fixing-geometry-in-arcpro-v-qgis/m-p/761588#M33213 WendyDorman 2019-05-21T14:47:24Z Re: Differences fixing geometry in ArcPro v.
