Hiding the Corridor: Custom Styles

Navigating corridor visibility in Civil 3D can be a maze. This blog illuminates the complexities when custom style configurations or intricate subassemblies come into play. From the pitfalls of overly simplistic code set styles to the detailed solutions, discover how to masterfully control corridor visibility with precision.

Typically, the corridor model is viewed but not plotted in plan views.  As it serves as a great guide to visualize where design is taking place, still the need to control its visibility is important.  But when custom style configurations come to play or complex subassemblies are used you might find some issues trying to control the corridor display.

First, we will be using “_No Display” styles for Point, Link, Shape, Material Fill Pattern and Feature Line styles available in the out-of-the-box template. 
Then, let’s look at creating a “Simple No Display” corridor code set style.  It will be “simple” in the sense that it will strictly use the 2 rows: 
     •    <default>
     •    <no codes>
All available cells within those 2 rows will be set to a “_No Display” style, which as shown above will have ALL components within each respective configuration OFF.

THE ISSUE:  too simple of a Code Set style.
What was found is that Civil 3D doesn’t take advantage of the “<default>” configuration field when creating a “simple” 2-row code set style definition.

 
THE SOLUTION:  Detailed No Display Code Set style.
Found that the code set style HAS to call EVERY code that is being in the assembly and set it to a “_No Display” style to shut off it’s display.

The creation of a “Detailed No Display” code set style is easy enough.  Again, let’s create a new code set style, this time we will take advantage of the Import codes... button.
 

By selecting the on-screen corridor, it will read the full set of codes and add them to the list.  Then, it is a matter of ensuring that all the rows of are using the _No Display or <none> styles. 

Then, this expanded configuration can put it to use and see the corridor disappear as originally intended via the use of styles (notice only station labels are shown below):
 

We hope this 2 part write-up may have helped you understand how to control corridor visibility by working with correctly configured code set styles.
