In today’s session we’ll explore a tool in Civil 3D called “Minimum Distance Between Surfaces”. This tool makes it easy to identify and delineate the intersection between two surfaces. (It does this by tracing the intersection as a 3D polyline.) In the recording I demonstrate how the tool can be used to help identify potential flood areas within a property boundary.
The inspiration for this session comes from Simon Noyola Rivero who posts a ton of valuable content on his YouTube channel. You can find it here…    / @simonnoyolarivero
