Customer collected data on a collapsed wall (not a scan). Remaining wall face (at edge of collapse) and some data of exposed slope. They needed to determine the face surface area. They tried a polygon (drawn in 3D) and surface properties (2D area). We ran a Surface Information report and was able to get a 3D surface area. They essentially had two points along the top, nearly twice the width as the bottom opening after clean up, and points at each block step down each side. The surface filled in those "step" areas with extra links. We weren't able to trim out those links because we could only see them in 3D view.
It would be nice if we could get a 3D surface area on closed objects that are 3D; linestrings, polygons.. Or trim in 3D.
