Creating 3D model from x,y,z survey data

[burly]

Hi all, I am new to this site and I am an land surveyor using AutoCAD 2012. Just new to 2012 version, previously used 2005 version.

 

My question is:

 

Is it possible to (and how do I) create a 3D model of a ground surface from field survey data which has been collected. The data i have is currently in Leica GSI format, and has x, y and z coordinates. I can easily transfer this into a .csv file i necessary.

 

Anyone any ideas?

 

Much appreciated guys!

Maybe it could be done with a program called CADTools. Check it out.

Do a web search there are some other freebie survey tools out there that will do surfaces and road stuff. EZYSURF ?
