topic Subtract/delete topology errors from original polyline feature class in Geoprocessing Questions https://community.esri.com/t5/geoprocessing-questions/subtract-delete-topology-errors-from-original/m-p/277169#M9540 <HTML><HEAD></HEAD><BODY><SPAN>Dear all,</SPAN><BR /><BR /><BR /><SPAN>I have the following problem. I have made a topology between two polyline feature classes (Must Be Covered By The Featureset of), this resulted in an error topology file. From this topology file I made an feature class with the Export Topology Errors tools. So now I have an Errors feature class (RED line) file and the original polyline featureclass(BLUE line) file where I based the topology on. I attached a picture. </SPAN><BR /><BR /><SPAN>Now here comes my problem, how can I 'subtract'/delete these errors from my original polyline feature class. Even a bigger problem is that some errors are not completely covering the original polyline, so at some polylines only half of the polyline needs to be deleted. Is this even possible? </SPAN><BR /><SPAN>Something else: there are around 60.000 error lines, so it's a large dataset. </SPAN><BR /><BR /><SPAN>thank you so much in advance!</SPAN><BR /><BR /><SPAN>greetings from the Netherlands,</SPAN><BR /><SPAN>Matthijs Kok</SPAN></BODY></HTML> Wed, 20 Jul 2011 08:37:49 GMT MatthijsKok 2011-07-20T08:37:49Z Subtract/delete topology errors from original polyline feature class https://community.esri.com/t5/geoprocessing-questions/subtract-delete-topology-errors-from-original/m-p/277169#M9540 <HTML><HEAD></HEAD><BODY><SPAN>Dear all,</SPAN><BR /><BR /><BR /><SPAN>I have the following problem.
