You cannot 3D print a point cloud. A 3D printer needs a watertight mesh (STL). Converting to 3DS first (then to STL) allows you to repair geometry for physical fabrication. You can execute a specific command to wrap the
CXI uses "Real World" coordinates (UTM / State Plane). 3DS uses an arbitrary local grid system. Your 3D model might import 100 miles away from the origin. Always scale and transform the mesh before exporting. A 3D printer needs a watertight mesh (STL)
