GEOPAK Corridor Modeler Questions

I am a long-time GEOPAK user, and  I am looking into the new Corridor Modeler approach of roadway design.  I have attended a few Distance Learning classes and I believe I understand the basic workflow, but I have run into several snags.  Can anyone address these from a GEOPAK perspective?

  • I sucessfuly imported our ddb file into a xin in order to define styles.  I found our ddb file's naming convention is a litte complicated, so I then found a sample xin somewhere that I would like to borrow heavily from.  How can I edit a xin file from within GEOPAK?  Is this possible, or do I need to edit a ddb and then re-import it into an xin every time?
  • I have created a a template for a rural section.  I would like the ability to have a ditch bottom point follow a special ditch profile and follow a particular graphic element for its alignment rather than be at a fixed offset and elevation relative to the centerline.  How do I assign a special ditch profile(s), and how do I search for plan view graphics to define variable offsets?

I know exactly what I need to do in GEOPAK to complete my designs, but I can see the advantage of using a model-based approach offered by Corridor Modeler.

I have trouble justifying spending a lot of money on training on something that I am not even sure we would ever use for production work.

Thanks for any help,

    The Corridor or chain name is probably being added because you are creating the surface(s) with the "New Surface for Each Corridor" toggle OFF. This is the option used to merge several Corridors into one Surface Model with a specified name. If you toggle ON the "New Sur..." option each Corridor will generate a separate "mySurface.dtm" and eliminate the need for prefixes being added to the features. The ability to merge corridors does require some method for naming features that does not append or overwrite features with the same name in a prior processed corridor.

    If you are merging several corridors then this prefix is needed. If you are not merging corridors the toggle can be ON with no problems.

    I am not familiar with the cross-section labeler you mention but I suspect it is a GeoPak equivalent to the InRoads Cross Section Annotation either way you now know how to control the feature prefix.
