Since Since Roadway Designer Roadway Designer does not read does not read directly from plan graphic elements, we directly from plan graphic elements, we need a way to make the application aware need a way to make the application aware of our graphics. We can do this by using of our graphics. We can do this by using the Plan Graphics import feature.the Plan Graphics import feature.

We can read the plan graphics based on We can read the plan graphics based on symbology, a DDB Feature or a MicroStation symbology, a DDB Feature or a MicroStation selection set.selection set.


When using Symbology or Feature, we can When using Symbology or Feature, we can setup a ‘search corridor’ based on a chain name, setup a ‘search corridor’ based on a chain name, a side and a beginning and ending offset.a side and a beginning and ending offset.


If our plan graphic doesn’t fit nicely into a If our plan graphic doesn’t fit nicely into a search corridor, we always have the Selection search corridor, we always have the Selection Set option. The user can just place any elements Set option. The user can just place any elements into a MS Selection Set and add them to the list.into a MS Selection Set and add them to the list.


Once all of our items are setup in our list box, Once all of our items are setup in our list box, we can import them. The resulting alignments we can import them. The resulting alignments are stored in the are stored in the .alg .alg file.file.


Data in the geometry database has a tendency to Data in the geometry database has a tendency to change throughout the life of a project. With that change throughout the life of a project. With that in mind, we need some way to keep our data in in mind, we need some way to keep our data in synch. In order to facilitate this, there is a synch. In order to facilitate this, there is a functionality built into the Corridor Modeling functionality built into the Corridor Modeling application called application called Smart UpdateSmart Update..

Every time you open Corridor Modeling, it Every time you open Corridor Modeling, it checks the data in the gpk against data checks the data in the gpk against data previously imported into the .alg.previously imported into the .alg.

Now that we have our data imported, we are Now that we have our data imported, we are ready to step into the CM workflow.ready to step into the CM workflow.

The first step is to access our The first step is to access our Create Template Create Template application.application.

The template library is composed of The template library is composed of Components, End Conditions and Templates.Components, End Conditions and Templates.


Components are Components are Individual “pieces” that Individual “pieces” that can be assembled into a can be assembled into a template. They consist oftemplate. They consist ofthings like pavement, things like pavement, shoulders, curb, walls, shoulders, curb, walls, etc..etc..


End Conditions are simply a special type of End Conditions are simply a special type of component that serves as the terminating point component that serves as the terminating point of the template.of the template.


Templates are a combination of components and Templates are a combination of components and end conditions that have been assembled to end conditions that have been assembled to represent a particular roadway condition.represent a particular roadway condition.


When components and end conditions are When components and end conditions are created, their individual elements are assigned created, their individual elements are assigned styles (drafting standards). This controls how styles (drafting standards). This controls how the elements arethe elements aredisplayed.displayed.
