A line is a straight distance between two points. Poly comes from the Greek word meaning many. Hence polyline means many lines. In AutoCAD : ( Its a little different a polylines can be a single line ) A line is not editable until its been converted into a polyline. Lines joined together will not form a closed loop untill they are joined. Lines will not join unless they are converted to polylines. A polyline can be a straight or an arced distance between two or more points. Polylines are editable they can be joined together to create closed loops. Polylines can be converted into splines and back again. The difference between using a line and a polyline in AutoCAD is that it is likely that at some point you will be converting that line into a polyline although it depends completely on what your doing.
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 pyramidal frustum whose bases are n-sided regular polygons iswhere a1 and a2 are the sides of the two bases.Note: cot(x) = 1 / tan(x)For example, I was not provided my a's to calculate the volume my pyramidal octagonal frustrum. I was provided only an overal width (let overal width = W) so I had to calculate a1 with this equation:a1 = W * (√2 / (2 + √2))Then with the given h I solved for the overal width for the top octagon using trigometry;Used the same a1 equation but for a2;Then used this equation to find my volume:It works, I tried it and proved it with AutoCAD using the command MASSPROP
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.
