AutoCAD Civil 3D continues to be Autodesk's solution for detailed design and project documentation for infrastructure projects. The AutoCAD Civil 3D 2018 version focuses on three major themes - design efficiency, documentation preparation, and interaction. Here are some of the most important new features in AutoCAD Civil 3D 2018:
Launch InfraWorks — The new InfraWorks ribbon in AutoCAD Civil 3D 2018 now gives you access to InfraWorks-related commands and enables you to launch InfraWorks directly from that ribbon.
Resolve Corridor Bowties — In AutoCAD Civil 3D 2018, when you have corridor tangents intersect at a corner, or the corridor is created at a fixed width, the inner and outer corners of corridors are now cleaned up automatically. You can even clean up corners from corridors you bring forward from prior versions of AutoCAD Civil 3D by simply making an edit to the corridor and rebuilding it. And, you can use the Clear Corridor Bowties command, when the corridor is created at a non-fixed width (such as when daylighting to a surface).
Plan Production Tools — New drawing templates have been added in AutoCAD Civil 3D to accommodate the ability to create plan/plan and profile/profile sheets. In addition, the plan production tools in AutoCAD Civil 3D 2018 allow you to more quickly create construction documents by allowing you to create plan(s)-only, profile(s)-only, and section sheets.
Connected Alignments — The new connected alignment capabilities in AutoCAD Civil 3D 2018 allows you to create a new dynamically linked alignment and profile that transitions between two intersecting alignments and their profiles. You can use this feature to create a curb return, an exit ramp, a merging/diverging road, or you can connect an existing road with a proposed road.
