Sir, a .LAS file contains millions of points, not only 0.5k...
thank you very much but i knew the LAS files have a millions of points, the 0.5K points was only example.
Do you know how can i select and cut only a freatured area?
Well, I guess you can't crop a .LAS file in Autodesk environment, while it's possible with opensource software.
A clever workaround would be the following:
I was just working on a Lidar file earlier today in MAP 2012 and noticed that there was a command to do a Spatial Filter when indexing the file. Unfortunately, it's another function of MAP that doesn't work very well. I kept getting error messages and gave up on trying to do a location filter.
If you were to consider third party software, MapWorks Surfaces contains a Mass Points Processor that will let you select multiple LAS files and a bounding object or rectangle. If a LAS file hits outside the boundary it's ignored completely (for speed).
I tried your sistems and i got my objetive whit Global Mapper whit autocad map 3D was imposible.
Thank you very much to everybody for help me
