Review Project Explorer for Civil 3D
Samir covers the basic features, known issues, and significant advantages of Project Explorer pretty well.
Glad he mentions the current Feature Line Site membership requirement and like his perspective on the value of Compare in the PE interface.
Given the length of the webinar not a lot about Alignments, Profiles, and Corridors PE functionality except a quick but valuable peek.
PE can change the way we work and think about Civil 3D. Don't take PE lightly.
