Add a field called 'Layer' to the feature class.Īlternately, use the User Interface (UI) or the Create Field Alias geoprocessing tool to provide a field alias for an existing column with the alias name of 'Layer'.Īnother option is to use the field info parameter of the Make Feature Layer geoprocessing tool to temporarily rename a field to 'Layer', which is used to provide the valid CAD layer name values to the Export to CAD tool.In this way, exported entities can take advantage of predefined layer names and any of their default layer symbology to quickly and easily create well-formatted CAD data. It is often useful to populate the feature classes' 'Layer' field with existing layer names that are already included in a CAD seed file. When a feature class contains a field that is named, aliased or renamed in a geoprocessing model to the name ('Layer'), valid values in that field are used to control the destination CAD layer name of each exported CAD entity. This procedure uses the Export to CAD geoprocessing tool's extended functionality to control the CAD layer by including a specially named field in the output feature class.
