Using the Section Editor

To understand what the Section Editor is and how it works, let's review how a corridor is built. An alignment and profile are combined to create a 3D chain, and then an assembly is repeatedly inserted along that 3D chain to create the full model. As you construct the assembly, you are looking at a static version of the cross-sectional geometry of the road. This version does not reflect the way in which the subassemblies interact with the targets you have assigned to them. However, the Section Editor enables you to actually view each assembly insertion in cross-section view, including any interactions involving targets. In addition, you can use the Section Editor to make edits to each corridor section and perfect your ...
