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.
You can use 2D commands on certain 3D models while you are in 2d modelspace. Color, for instance, or lineweight. Elevation and thickness, as well, if the 3D model is built to do those. You can certainly use Erase, Change Properties and so forth.
DXF - This is not really an AutoCAD format but an industry standard, but one that you should be aware of. DXF stands for Drawing eXchange Format. This is a very standard format that is used but many different CAD and graphics programs. This allows users to exchange drawings even if they don't have the same program. When you use the DXF format, some objects may change their appearance when re-opened. As with DWG formats, DXF formats vary from different releases. You have the option of saving the files as a DXF or you can use the DXFOUT command, conversely DXF Files can be imported using the DXFIN command.
The volume of a truncated octagonal based pyramid can be calculated using the formula V = (1/3)h(A1 + sqrt(A1A2) + A2), where h is the height of the pyramid, A1 is the area of the larger octagonal base, and A2 is the area of the smaller octagonal base. This formula takes into account the three-dimensional shape of the pyramid and the difference in area between the two bases. By plugging in the values for h, A1, and A2, you can calculate the volume of the truncated octagonal based pyramid.
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.

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.
An AutoCAD viewer is a program used for viewing and editing AutoCAD drawing files. Typically you can create JPG files from your drawings and print them using an AutoCAD viewer.
