Slide 2
2011 Autodesk Class Summary Class: CI4031 This class focuses on
the enhanced superelevation functions now available in AutoCAD
Civil 3D, specifically axis-of-rotation (AOR). Using the new
LaneSuperelevationAOR subassembly to define potential pivot points,
users can define cross-sectional components in a very flexible
manner and allows the dynamic editing of the axis of rotation to
quickly validate various alternatives.

Slide 4
2011 Autodesk Agenda Identify Key Prerequisites For Design
Success Review the Big Picture Review new Superelevation Wizard UI
Review the new LaneSuperelevationAOR subassembly Ex. 1- Create a
corridor for simple roadways using Axis of Rotation Points Ex. 2 -
Create a corridor for divided roadway. Control median geometry Ex.
3 Review Towards Crown SA parameter Ex. 4 Real life example
Slide 5
2011 Autodesk Key Prerequisites for Success 1. Alignment Layout
& Design final or approaching final layout 2. Roadway Design
Defined Number of lanes Divided or Undivided roadway Crowned or
Planar roadway section Distorted or maintained median
Slide 6
2011 Autodesk Review New UI - Assigning Pivot Method
Slide 7
2011 Autodesk The Big Picture 1. Define Alignment 2. Select
Axis of Rotation Point 3. Calculate Superelevated Lane Slopes Build
a corridor that uses all this data. 4. Create an Assembly that
supports Superelevation and Axis of Rotation
Slide 8
2011 Autodesk Using The New LaneSuperelevationAOR
Subassembly
Slide 9
2011 Autodesk Ex. 1 Create and edit a corridor for a simple
roadway section using Axis of Rotation Points
Slide 10
2011 Autodesk Creating Assemblies for Divided Highways Curve to
the Right Maintain Median Shape Distort Median Shape
Slide 11
2011 Autodesk Ex. 2 Create a corridor for divided roadway.
Control median geometry maintain or distort shape.
Slide 12
2011 Autodesk Build divided road from baseline Toward Crown
Toward Crown Construct Assemblies Using Toward Crown slope
direction Build divided road from crowns of barrels Away from
crowns
Slide 13
2011 Autodesk Ex. 3 Create a Divided Crowned Assembly using
towards crown subassembly parameter.
Slide 14
2011 Autodesk Ex. 4 Authentic application: Adjust pivot method
to assist with managing design constraints
Slide 15
2011 Autodesk Pivoting about ETW (or other non center point) is
possible Summary Controlling median geometry is possible Many
existing subassemblies behave well with non- center pivot points
You can add AOR support to your custom subassemblies
