Life is too short for manually purging CAD files from your Revit model. With DWG Explorer (renamed to CAD Files Explorer since version 2019):
1. You can instantly see all CAD files in your Revit project or family. These include DWGs as well as any other CAD file types Revit accepts such as DXFs, DGNs, SKPs or SATs. Each file will show if it is linked or imported, independent or view-specific. View-specific CAD files will show if they are still visible in their host views. If not, you know what to do!
2. You can instantly select & show each CAD file in its host view, delete it, or list all views & sheets where that file is visible. The app can then instantly open each of these views & sheets and zoom to the CAD file in question for you.
3. You can directly delete CAD file names that show under VG > Imported Categories which may still be there even after you have removed all their copies from the model. This is also the quickest way to delete multiple copies of the same CAD file from Revit.
4. You can delete object styles resulted from someone exploding a CAD file in Revit. This will help reduce the negative impact of exploded DWGs on your model performance. These can be easily spotted in our report as their names follow the format [Original CAD file name].[CAD layer name].
