What is the procedure to draw a line more than one time and save it automatically?

- AutoCAD allows the file to be written in multiple instances of the processes and it limit the resources that needs to be used as well. - When a new line needs to be drawn the process opens up another file in a new session to write the file. - AutoCAD allows saving multiple drawings to be saved for each session and it can be used to create the application. - The files are saved by using the file extension as .dwg and it can be modified using the browser. - The file extension needs to be hidden and it needs to show allowing the selection of the option as well. - The file modification takes place by checking the AutoCAD operations and opening up of the drawing.
