Alignments, profiles, and profile views

- [Instructor] As we get into our vertical geometry, it's good to understand the relationship that profiles have with alignments. So, profiles really are the road or whatever the alignment represents, the linear path, if the linear path, the earth was cut at that linear path and so, you need a linear path defined to create a profile. Now, of course, you have the existing surface or earth at that linear path and then maybe a proposed at that location. More than that, to properly show a profile, you need some means to view it. Civil 3D was built on top of AutoCAD. AutoCAD's really focused on that Cartesian coordinate system. Everything has an X, Y and Z value. Profiles don't have X, Y, Z. They have a station and an elevation for each portion of the geometry and that's really the focus there. Our profile is nothing more than station elevation values with additional information if there's any curves. So, it needs to recognize where in the AutoCAD model space that station and elevation are…
