I have a project currently where information on a site has been derived from a LiDAR survey, for contours across a large site. I also have a site survey from 1966 and in the intervening years considerable amounts of fill have been brought onto this site, and raising the level considerably and in some places up to 40 feet or more. I am interested to know if a stylus can be used to trace the original contours from the 1966 contour plan, then to be used as an overlay on the current levels, to see the difference from then to now, to identify possible areas of subsidence and water drainage issues after heavy rain etc. The site is approximately 198 acres (80 hectares) Any information would be greatly appreciated.

Hi everyone. I worked in MicroStation on classification of LIDAR. And after I converted .las to .laz I used a macro for .laz files to classify from one class to another. So, that operation broken the shape of my files. I don't have any backup for files so if I don't find a way to return the right shape of .laz files I have to start my work from the start. Is there any way to fix shape of .laz? Or maybe I can fix it manually to set, somewhere, the right coordinates for each corner of the .laz file? I attach examples of shapes which are right and wrong and examples of warnings which I received when I tried to convert broken .laz to .las by laszip. I will be appreciated if somebody helps me.

this looks interesting : https://developer.apple.com/videos/play/wwdc2022/10127/ parametric file seems to be brought straight into Blender. On another note, scaniverse on app store is excellent (and free!) , and the point clouds import nicely into vectorworks.

I have been trying to import a large point cloud and I cannot seem to figure out how to get it to the right scale. I have tried every combination of units, both pre-setting drawing units and changing the point cloud import units and nothing I do has yielded successful results. The import has yet to come in at the right scale or x,y,z location. Anybody out there with some tips?
