YouTube's auto-generated channels are created by algorithms to collect trending and popular videos by topic. Auto-generated channels act like user channels in that you can subscribe to them and stay updated on new videos. YouTube's auto-generated channels begin with a # symbol (i.e: #SolidWorks, #CATIA, #Autodesk, #ProE, etc.) and contain a notice in the About section that they are auto-generated.
The clear advantage of auto-generated channels for video information is the enlarged content, filtered for usability. Yes, of course all of the big players have their own channel, but the information in a sponsored channel is selective and controlled by the sponsor. In other words, it is limited by what they want you to see. However, an auto-generated channel will include all video content relevant to the topic. Thus, auto-generated channels provide you with the best of everything related to the topic, regardless of who created the video.
For CAD users, scripted instructions of Help sections, and company-sponsored sites all have their place in the scheme of things. Video instruction though is such a powerful tool as it provides clear, visual step-by-step instruction. So it's nice to know a collective / sorted resource of video information is available with seemingly little effort. So if you're interested in viewing features of a CAD program, training, tips, or whatever is relevant to the topic, then the auto-generated hashtag # channel is an excellent resource to view the most relevant information quickly.
As an additional benefit, the side bar of any channel includes Featured Channels that might be of a related interest to the viewer as well. Thereby easily expanding your pool of available resources, as needed. And you don't have to limit yourself to CAD, as YouTube is auto-generating an ever increasing number of channels in any topic, including music / musicians with selected entire album content of which you can subscribe. Yes, what more could you ask for from an algorithm!
