Hi,
>> The point cloud was visible in 2D Wireframe making it easy to line up your model with the point cloud
You can do the same in visual style "Wireframe".
>> I could select points using the node object snap
You can do the same now, and even more! You do have now a complete set of object snap help especially for point cloud:

>> In 2017 when selecting the pointcloud I have to zoom out
I can't see that issue, I can select the point-cloud at any zoom factor, do I do anything different to you?
In this video I try 3 different zoom factors and click to select, then zoomed out to see the border as selected item.

>> In 2014 the bounding box section planes was easy to use
Maybe I misunderstand "bounding box section planes". I use now the section planes plus the commands helping then to create new objects based on (virtual) edges in the point cloud, or creating automatic section lines ... not available in 2014 
There you find a video (not the best sample, I know) which shows how fast you can get geometry from a point-cloud. The resulting lines (e.g. from the walls) are the fastest option to built up your further redesign (imho).
Let's know if that news are useful for you or if your results differ to mine (in that case verify your AutoCAD 2017 is up-to-date/on Update 1.1).
