Although you can find several examples in this Blog where you can see how to export 3D objects to Google Earth basing their altitudes on an attached data or on their constant Z elevation, you can also export native 3D objects (such as Polylines or Lines in CAD versions). The case study reviewed in this Blog entry illustrates a very common scenario
Blog: 3D
Spatial Manager Terrain Assistant, available in the CAD versions (AutoCAD, BricsCAD and ZWCAD), provides the user with intuitive tools for processing 2D/3D Terrain information (Points, Contours, and Digital Terrain Models). In this blog entry we review the possibilities that the application brings to the generation of Contours starting from different data types and applying different options for created objects
While 'Spatial Manager' allows you to handle any type of 3D information and therefore export 3D-point tables from your drawing or map, there are times when the points Z-coordinate information is in a label form. Here you will find a little trick to get the XYZ coordinate tables in these cases
'Spatial Manager' includes an option to manage the Z coordinate when importing spatial data (Shapefiles, Google Earth KML, ASCII, Excel, LiDAR, etc.) into AutoCAD, BricsCAD or ZWCAD drawings. It is a configuration little known by many of the application users and it may hide some features that need to be properly understood to optimize the results of the import process
