I have a large point cloud in dwg-format, that I need to import into TBC, and calculate grounds Contours out off. The data is from aerial laser scanning, so it is far too dense to get reasonable results with smooth lines at 1m intervals. The contours come out jagged and sharp because the original material is too dense.
How can you thin out the point cloud before calculating the Contours? For example, reading in only every third point, etc. For the life of me, I have not found tools in the program for this! Or do I need to convert the cad points first to something else, and do massive work arounds before calculating the contours?
Have you tried Sample Region?
