I need to create a map based on what I have available in a CAD document. I have minimal past experience with CAD files or the CAD program, and so I am trying to convert a CAD file to ArcMap so I can more easily manipulate the data and build on it there. I've added a coordinate system to the CAD file, but when I add it to ArcMap or try to convert to geodatabase, the CAD feature classes are empty. I've tried adding the CAD data by just clicking the add data button and adding the CAD file, and also by using the geoprocessing tools for converting from CAD to geodatabase. Either way I've tried, the CAD feature classes appear empty, with no data in them so nothing is displayed and attribute tables are empty. Perhaps I am missing a simple step... But any suggestions on how to successfully import a CAD file into ArcMap would be greatly appreciated.
