This video shows how to generate contours from LiDAR using Equator, and then how to create a surface in Civil 3D. Contours are a vector data type and are often stored in SHP or DWG formats. gpx file is on GPS track points recorded by GPS devices, it is a lightweight, xml data-interchange format. LAS or LAZ files and select which Object Classifications you want to read. Once you have a DEM, you can create other derivative data layers, such as contours. AutoCAD / BricsCAD / ZWCADSpatial Manager Import LiDAR data providerYou. High resolution GeoTIFF, PNG, LAS/LAZ, OBJ and OGC 3D Tiles formats. Check out this article to learn more about LiDAR/DEM/Contours and how to create smooth contours in Civil 3D. Preview and export elevation contours to AutoCAD, ShapeFile, GeoPackage. The nice thing about working with DEMs is that the resultant Civil 3D surface will typically produce beautifully smooth contours, which are preferred for many applications (such a presentation material). ![]() DEMs are often a raster data type stored in geoTIFF format (which Civil 3D can easily work with). Method 2 involves simplifying the point cloud by converting it into a model with a desired resolution, e.g. ![]() If you don’t have Recap, or if your Civil 3D is crashing because of massive point clouds, or if you want to save time then method 2 is for you. Method 2: LAZ to DEM (geoTIFF) to Civil 3D
