What about physically cropping the huge point cloud..?
You can do it by means of the opensource Qgis, Neil.
If you don't wanna learn any new tool, gimme the link to that .LAS one, and the cutting shapefile.

Not directly, so we should first extract the triples XYZ from the .XML, thru an Ascii editor able to handle millions of rows (e.g. Textpad).
Could you zip the XML on a file sharing as Dropbox..?
I followed the procedure detailed in help - but it din't seem to have any effect on the surface.
In the end I extracted the points from the surface and wblocked them as plain AutoCAD points to a dxf which worked

I see, I was guessing (so help & Tut's I go)
I just tried that with a Tin surface and a Lidar data set exported to Lxml Both worked fine. The only thing was I had to rebuild the snapshot each time before it would regenerate (I also had to manually regen).
I'm guessing it may purely be down to the size & number of points. I know creating surfaces from point clouds reduces memory useage but the point cloud its self is restricted to a set number of points. My Lxml file had 179772 points and worked fine. If anyone else can see if they can do this with a greater number of points (working up to your size) it would be useful to see if / when it fails.
