new command: PLCONTINUE

[Michiel.Valcke]

The function ARC has a subfunction <CONTINUE> 

Could the function PLINE also get this subfunction.

The idea would be that instead of just adding a single vertex you can draw a new polyline as an extension of an existing one without having to join them afterwards. Once you start drawing you would simply have the same functionalities as the PLINE command.

it can either work as a separate command (PLCONT) or as a subcommand of the PLINE or PEDIT command.

If you enter the command, AutoCAD could prompt you to select a polyline to continue and you will immediately start from the last vertex to continue. 
At this point you get the option to reverse the Polyline in case you wish to continue from the first vertex. Once you put a new vertex the option to reverse no longer shows.

the function would not work on closed polylines. In case a closed polyline is chosen a prompt will tell the user why that polyline is not a valid choice.

I think this should be a basic Autocad functionality, carrying through in all different Autocad versions.
