The main model consists of a nested model called VCSetup as shown in the screenshot.&nbsp; VCSetup takes the selected features, uses "Get Count" to get the number of features and then the "Calculate Value" is used as a boolean where if the number of selected features is greater than 0 and less than 10000, it is true and else, it is false.&nbsp; Calculate Value is set as a precondition to the next step, "Copy Features". These features are then set as parameters to feed the export to CAD tool.&nbsp; The issue is, if the "Calculate Value" is false (no features from a feature class are selected), the "Copy Features" does not run and therefore, the Export to CAD tool fails as it says "Error 000229: Cannot open in_memory\Water_Pipes".&nbsp; How do we get around this?</P></BODY></HTML> Thu, 27 Jun 2019 22:38:59 GMT SachinChand 2019-06-27T22:38:59Z Export to CAD in Model Builder https://community.esri.com/t5/modelbuilder-questions/export-to-cad-in-model-builder/m-p/816978#M1295 <HTML><HEAD></HEAD><BODY><P>We have a model that runs within ArcMap where it takes the selected features from several feature classes in an ArcMap session and converts them to a dwg using the export to CAD tool.
