Advanced Corridor Slope Patterns: Enhancing Plan Production in Civil 3D

2025-01-11_9-29-47.jpg

Creating a detailed and accurate corridor design in Civil 3D can be challenging, especially when it comes to introducing benches for corridor daylight. One of the major pain points is the lack of a stock subassembly tool to make continuous slope patterns along the corridor daylights, from slope one to slope n. This process can be particularly time-consuming when dealing with long axes and requiring the splitting of daylight slope patterns into different sections.

 

However, there's a solution to this problem using Subassembly Composer, which allows for the use of the same point codes for all the daylight break points, even with temporary names. Let’s explore the advantages and disadvantages of this approach:

 

Advantages:

  1. Clean Patterns Along the Corridor: You achieve a nice and clean pattern along the corridor, enhancing the visual and functional quality of your designs.

  2. Time Efficiency: This method frees up more time for you to focus on different tasks, improving overall productivity.

  3. Eliminating Tedious Tasks: Say goodbye to at least one boring task, making your workflow more enjoyable.

Disadvantages:

  1. Overlapping Lines: You'll need to clean up multiple overlapping lines along the daylight because you have the same code for all the subassembly points.

  2. Custom Subassembly Creation: Creating custom subassemblies for corridor daylight will take some time, requiring a bit of upfront investment.

By addressing these pros and cons, you can make an informed decision about incorporating this technique into your corridor design workflow in Civil 3D. Not only does it streamline the process, but it also opens up opportunities for more creative and efficient design solutions.

Great! Let's break down the steps for creating a subassembly for daylight in Subassembly Composer:

 

Step 1: Open Subassembly Composer

  1. Launch Subassembly Composer: If you're new to this tool, spend a few hours getting familiar with its interface and functionality. It's quite user-friendly.

  2. Start a New Subassembly: Click on New to create a new subassembly.

Step 2: Define the Daylight Subassembly

  1. Create Daylight Cut and Fill:

    • It's advisable to have two different pattern codes for cut and fill. This allows you to control pattern colors later in the software.

    • For example, use "DL_Cut" for cuts and "DL_Fill" for fills.

Step 3: Bench Daylight Assembly

  1. Avoid Using Loops:

    • Instead of loops, use a series of conditional statements and geometry to create the bench daylight assembly.

    • Reason: Loops do not support if statements, making it difficult to handle scenarios where the bench does not find the Existing Ground (EG) target.

At the end, include a picture to give an idea of the overall subassembly. This can further illustrate its features and showcase additional capabilities, such as offset targets, merging ramps, intersection daylighting, and more.
