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

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.
