Civil 3D 2010 - CORRIDORS
from simple template models to powerful string based decision based models...:

We'll start with a standard basic model and extend it as follows:
  •Standard Modeling (basic 'template like' approach)
  •Target Mapping (String Based Approach)
  •Offset Assemblies (skewed Cross sections - has to be seen to be believed!)
  •Conditional Assemblies (add some serious intelligence to your model)
AND
  •   **MARKED POINTS for complex Modeling**
In a nutshell, marked points allow you to model from the outside strings in towards the CL instead the usual approach which goes from the CL out.
This is where the real power of the Corridor Object is exposed.
