You can create a TIN surface from points within RCS format point cloud scan files and RCP format point cloud project files created with Autodesk® ReCap™.
You can use the Create Surface from Point Cloud command to create a surface from several point clouds, selecting only the areas that you want to include and filtering out non-ground points so they are not included in the resulting surface. When using this command, you can select entire point clouds or areas of point clouds to include in the surface. You can select areas of point clouds by using window selections, by defining polygon areas, or by selecting existing closed polylines in the drawing.
If the quantity of points in all the selected point cloud areas exceeds two million points, then the areas are subdivided for faster point cloud processing.
- Attach one or more RCS point cloud scans or RCP point cloud projects to the drawing. For more information, see About Working With Point Clouds and To Attach a Point Cloud to a Drawing.
