BIM isn’t Just for Buildings. What it means for Public Sector Highway Design

Despite its name, the many benefits of building information modeling (BIM) are no longer restricted to the architecture and building industry. BIM is quickly establishing a foothold with civil engineers, public sector transportation, and infrastructure officials as a tool to deliver design projects faster and smarter thanks to technology like AutoCAD® Civil 3D® and Autodesk® Infrastructure Design Suite (a comprehensive software solution for planning, designing, building, and managing civil and utility infrastructure – also known as the ultimate “BIM for Infrastructure” solution).

Mastering Civil 3D's Intersection Wizard to Create a 4-Way Intersection

Civil 3D contains many engineering tools for roadway design. One of these tools is the Intersection wizard. The wizard walks the user step by step through the intersection design process and parametrically designs three or four way intersections. In addition to intersection design, the wizard defines widening for incoming, outgoing, or both lane types. This article describes the use of the intersection wizard to create a four way intersection that maintains each road’s crown elevation.
