    This class is designed to articulate the workflow of creating a topographic survey model within AutoCAD Civil 3D software by using scanner-generated point clouds (Trimble SX10) processed within InfraWorks software. Initially, we will import our point cloud into InfraWorks where it will be analyzed, processed, and filtered. We will then export data from InfraWorks and import it within AutoCAD Civil 3D for additional processing. Once in AutoCAD Civil 3D, we will process data again to create a topographic survey model. To demonstrate this workflow, we'll focus on an actual project containing a retaining wall (75 feet long x 20 feet high) in need of replacement. In this instance, our team decided to supplement a traditional (total station) topographic survey with scanner-generated point clouds to save on field time, and also to promote the safety of our survey crew.
