I was supplied with LiDar data in XYZ format. I import the blocks via point clouds, each seperate block in a seperate point cloud. The point cloud details show that the cloud contains about 2.5 million points. When I create a surface from the point cloud it will only use 48 000 points from the 2.5 million. I combined all my point clouds (27) to create a large surface, and it only contains 77 516 points. By my calculations it should contain 2.5 million x 27 = 67.5 million. Is there any way to have my surface contain all the points from the point cloud?

Solved! by mathewk. See the answer in context.
Try changing the Point Cloud density to a higher number. I think by default it is only set to 15 out of 100.
I have had a very difficult time when importing the lidar data as point files. Extremely slow and most times Civl 3D will sotp responding. I open the task manager and it shows its only using 10% of the CPU and 10% of the Ram.
Matt's right. You are better off "attaching" the point file.
In any event, using every single point of a 60M +/- point scan wouldn't produce much of a difference, except for a horrifically unmanageable file size. For the most part, the intermediate points will lie on a the surfaces formed from the other points. They may be a little higher or lower, but shouldn't be signficantly so.
Kind of like modeling every nuance of a thread and rounded bolt head on a screw for a 1:50 drawing.
Probably more like 15%, where you are showing combined activity in a hex-core processor. If you switched to individual core monitoring, you would see one of the cores pegged at or near 100%.
Matt, it took me a little bit to figure out what you meant, but I understand. Create a surface and just attach the point files instead of importing the points and creating point groups and attaching them. It sounds like a much better method than what I had orginally attempted. I will give it a shot and let you know how it works. Thanks for the help!
