JW_cad Viewer is an Android app developed by junkbulk that allows users to view JW_CAD (JWW, JWC) and DXF files on their smartphones or tablets. The app comes with a dimension measurement function, which allows users to measure the distance between two points. Users can also choose to show or hide layers, select a file from the file manager and open it (some file managers are not available), and snap the measurement point on the line or at the end point. Various settings can be made from the setting buttons, including specifying the encoding for garbled DXF files. This app is free to use but displays advertisements. Please note that the author shall not be liable for any damage caused by the use of this application, and the app is not an official JW_cad.
