GEOPAK Corridor Modeler Questions

Offline Josh M over 14 years ago

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,

Is there an equivalent in Corridor Modeler to the GEOPAK Criteria "Draw Cell" command? In other words, is there any way using templates to draw cells in cross-sections?

If the EC's are not hitting ground correctly make sure the existing ground surface that is plotted on the sections is from the .dtm file and not the .tin. There may be slight differences between the existing ground Geopak .tin and the .dtm file that gets created from the Corridor Modeling application.

When you develop your templates you need to pay attention to how the components are created. Components can be created as Open or Closed. If you are using Geopak EW to calculate pavement quantities you would most likely want to use Open components and create your template like Criteria would draw it.

And make sure you are dropping templates at the cross section stations. If you drop a template every 50' but cut sections at 25' or 10' then the tie in point will not be at the ground except by chance.

Josh,

I am at a situation that you were in.

My corridor modeler does not have option to select right DDB file and import into .XIN. I imported the default_style, ran my corridor, cross sections look great. As I go create cross sections, I got a message "No .XIN file is assigned", and the cross sections thus created does not show component linewok. Weird thing is XS shows point descriptions, but no linework other than ex-surf. Any suggestion how can I import the right DDB file? see the snapshot where I do not have option to update DDB. I am on Geopak SS2 08.11.07.615.

Thanks to anybody responding...

Click the import button to create the XIN file

You need to check the GPK_ACBOOK_DDBSTYLES variable, it is pointing to the ddb you are using

See the wiki for other corridor modeler variables
