Can these files be imported into acad and manipulated without any other application? I an using acad 12 map 3d.

I believe they can be used with Autodesk Recap(a terrible program with no real survey functionality at all) but certainly not in Acad 12 map 3d. I am not at my work computer right now so i cannot verify 100%.

Not what you asked for, but of the software suites available, Global Mapper offers tremendous functionality with las files at a low price point. You have to get the Lidar module, so you end up at about $1100 all-in, but that’s a pittance compared to QT Modeler and other point cloud software. Not a shill for them, just a happy customer in the past. https://www.bluemarblegeo.com/products/global-mapper-purchase.php
Plus side is that it’s useful for tons of other stuff day-to-day survey stuff, too, with excellent handling of map projections.

You might be able to import the data set depending on the size of the point cloud. Your version of cad uses the Alice labs point cloud engine. We have used the Alice labs point cloud engine in the past, on small points clouds data sets; feature extraction is difficult and slow. We used it mainly to create a 3D picture for our line work.
Currently, Autocad uses Recap as its point cloud engine. It’s pretty decent as long as you have a subscription for the software. Once you create a recap project, you can attach the project (aka point cloud) within AutoCAD with just a handful of clicks-pretty easy. Extraction of features has improved but not as easy/intuitive as some software’s that are available on the market today.
I would recommend 3D reshaper to do feature extractions from your point cloud. I know cost may be a prohibiting factor, just thought I’d recommend what I use now.

Are you only trying to extract the xyz data?

Yes. I have Carlson to create what I need from the data.
