I am ultimately trying to create a TIN and contours from LiDAR data. I have created a point cloud using the xyz LiDAR data, but from that point I am stuck.
I created a surface, but can't attach data properly using the xyz LiDAR information. I get some parsing errors and a bunch of points don't come in because their elevations are "below given limit".
I don't have a DEM file, nothing except the xyz LiDAR data. A colleague with MapInfo made a DXF for me of the contours (he had no trouble creating them!) but my DXF comes in with "0" z values.
How do I get my contours? It's probably simple, but I can't see it, after probably 10 hours pulling out my hair and not eating or taking a bathroom break. OK, TMI.
I wish I had Eagle Point... so much freaking easier but oh well. I am fairly new at Civil 3D 2011 so please be gentle.
Thanks in advance.
