Why I can not open DXF file in LinuxCAD?
linuxcad my_dxf_file.dxf You need to start LinuxCAD with a new file and then enter: DXFIN my_dxf_file.dxf in the command area of linuxCAD. This is the proper way to read DXF file. LinuxCAD prints some diagnostic and progress information when it imports DXF therefore the standard output should be properly redirected to a file or /dev/null device or terminate at the valid xterm window.
