The Pathway section of the Site Layout tab is a collection of tools used to create and manage Driveways, Sidewalks and Driveway connections. The Driveway and Sidewalk tools allow you to quickly place parametric conceptual objects that are optimized into the site grading. You can then customize the objects by editing the properties to achieve a conceptual design goal. As you finalize your concepts and move on through the actual design process, the Driveway connection tool will help you transition from conceptual grading to design models.
