Scanned environments, or point cloud drawings, can encompass a large physical area. Even segmented data from Autodesk ReCap can be large and contain many elements in a single drawing.
To successfully extract relevant geometry from a large point cloud file, you can crop a point cloud into various sections. This allows you to work with a small area of the point cloud drawing in detail and extract it into 2D geometry.
You can use the PCEXTRACTSECTION, PCEXTRACTCENTERLINE, PCEXTRACTCORNER, and PCEXTRACTCORNER commands to extract geometry from each cropped area of the point cloud.
