A polyline is a line composed of many segments: for example the rectangle is a polyline consisting of four line segments.
In AutoCAD, a line is a basic geometric element that consists of two points and extends infinitely in both directions. A polyline, on the other hand, is a series of connected line segments or arcs that form a single continuous object. Polylines are versatile as they can have width, different line types, and can be easily edited as a single entity, whereas lines are individual entities with limited editing capabilities.
Line, is a basic command as a single line that can form into an object. However, this command can not be formed into three dimensions. To shape it needs to change the structure of the line to polyline
With GStarICAD, a polyline is a connected sequence of arcs and lines that is treated as a single entity. You can draw a polyline with any linetype and using a width that either remains constant or tapers over the length of any segment. When editing a polyline, you can modify the entire polyline or change individual segments. After you specify the start point of a polyline, a prompt box provides several options as you draw, such as Distance, Halfwidth, and Width. You can specify different starting and ending widths to create a tapered polyline segment. After you draw at least one polyline segment, you can use the Undo option to remove the previous segment. After you draw two or more polyline segments, you can use the Close option to complete the command by drawing a segment that ends at the start point of the first polyline segment you drew. Choose Done to complete the command without closing the polyline.
GstarCAD's native file format is DWG, so when you open an existing Autodesk AutoCAD file (2.5 to 2010), there's no file conversion and no data loss. GstarCAD also provides a full compatibility with AutoCAD command line,menu (.mnu) and script (.scr) files, hatches, fonts, complex linetypes, multiline text, lightweight, polyline, draw commands, audit & recover as well as AutoLISP and ADS. That means you can get to work immediately by using the AutoCAD files, commands and applications you rely on.
polyline is a 3d line where line is a 2d figure if a diagram has been drawn with polyline and line, if we click on the diagram made with polyline whole diagram will be selected where line didn't make it
Almost always, unless you are exporting the linework to another program. Some other programs don't like AutoCAD polylines, and prefer lines. On the other hand, polylines can contain data/features that lines can't, such as width and curves.
AutoCAD has a flexible subscription model, with new features available with each release and product update. If you have a perpetual license of AutoCAD 2016 or earlier, here’s what’s changed in AutoCAD 2017, AutoCAD 2018, AutoCAD 2019, AutoCAD 2020, AutoCAD 2021 and AutoCAD 2022.
How many versions of AutoCAD are there
AutoCAD was created in 1982-12.

Yes, a polyline can be left open, meaning the start point and end point do not connect to create a closed shape. This is common when representing paths or routes that do not form a closed loop.
AutoCAD can be learn by yourself. But for learning that you must have the program for doing AutoCAD. It must be downloaded or read the guide's book for the AutoCAD programs.
