I think that this tool is one of the most flexible roading tools that Vectorworks has. It allows you to change the width, add an intersection, and make all sorts of adjustments.
In the session we focused on site modifiers and site modeling in Vectorworks 2015. There have been some important changes in Vectorworks 2015. One of the most important changes is the ability to see errors in your site model visually. This may not sound like much in improvement, but everybody who sees it comments on how important this change is. We also looked at two of the new road objects, one of which we used to build a car park.
This session focused mainly on site modeling, creating steps in the site model, and creating a retaining wall that stepped along the site. The problem in this situation is the proximity of the retaining wall to the site boundary.
