Why does AutoDesk do anything that further confuses its users? Who knows? Be that as it may try an online search for "Civil3D 2018" and "point clouds" for starters. I see that there are a couple of videos by Steve Younkin and Todd Rogers on the subject. You might also look for information at the AutoDesk Knowledge Network. Much like airlines that started charging a fee for checked baggage, AutoDesk is now in fee-based mode and you can expect them to aggressively find more ways to ding their client base. And that's how business works like it or not. The customer really doesn't matter all that much in the scheme of things when you have a captive audience. Pay up or forego what you previously got for free.
