Infraworks needs to implement Civil BIM. After years of marketing it's time Autodesk actually implements Civil BIM so we can leverage an actual model based design. I want to be ablility to tell my kids that I'm designing curb and gutter instead of getting blank stares when I tell them I designing feature lines.
The curb and gutter objects need the ability to have a tools found for feature lines in Civil 3D. Allowing us to set elevations at certain locations, insert grade breaks, set grades along a path (and automatically removing the grade breaks I inserted earlier or not depending on a setting for this), talk to the pavement object (that will be part of another idea station idea) and have the pavement object react to the curb and gutter changes. Due to processing power limitations this could be updated at the press of a button.
The curb and gutter will have intellegent information tied to it such as a C or CN value, a mannings n value, and recognize the adjacent pavement to determine if the spread is allowable or if it floods the first floor of an adjacent building.
