Before drawing geometry, navigate to the tab at the bottom of the screen. Define these standard variables: CurbWidth (Double, default = 0.50 ft) GutterSlope (Slope, default = -2.00%) CurbHeight (Double, default = 0.50 ft) SubbaseDepth (Double, default = 0.75 ft) Step 2: Establish the Flowchart Logic
: Embed "if/then" scenarios directly into your corridor elements (e.g., varying ditch slopes based on cut depth).
To make a subassembly search out an existing ground surface ( EGcap E cap G Navigate to the tab.
: Create unified, reusable catalog components for your entire organization. 2. Interface and Workspace Overview
[ Decision: Is P1 below Surface? ] / \ Yes No / \ [Construct Ditch Logic] [Daylight Slope to Surface] Create a named ExistingGround . Drag a Decision block into the flowchart. civil 3d subassembly composer tutorial pdf
Every subassembly begins at the , which represents the assembly baseline attachment point in Civil 3D. This point is created automatically. Step 2: Define Input Parameters Navigate to the Input/Output Parameters tab and create: LaneWidth | Type: Double | Default: 3.6m (or 12ft) LaneSlope | Type: Grade | Default: -2.0% PaveDepth | Type: Double | Default: 0.15m (or 0.5ft) Step 3: Create the Top Lane Geometry
Subassembly Composer is a visual programming tool installed alongside Civil 3D. It allows you to create custom subassemblies without needing advanced .NET programming knowledge. Why Use Subassembly Composer?
Subassembly Composer is a utility that comes with Civil 3D, which allows users to create custom subassemblies using a graphical interface. With Subassembly Composer, you can create subassemblies from scratch or modify existing ones to suit your specific design needs.
Used to follow feature lines, alignments, or polylines horizontally. Before drawing geometry, navigate to the tab at
In this tutorial, we have guided you through the process of creating a simple subassembly using the Subassembly Composer. With practice, you can create complex subassemblies to represent a wide range of corridor features.
Tutorials generally include screenshots of the SAC interface, showing exactly how the Flowchart, Preview, and Properties panels work together. Core Concepts Covered in SAC Tutorials
This guide acts as a tutorial, summarizing essential workflows for creating custom subassemblies that can be used in your Civil 3D models. 1. Introduction to Subassembly Composer
Civil 3D will fail to parse point, link, or shape codes unless they are wrapped in straight quotes (e.g., "Top_Lane" ). : Create unified, reusable catalog components for your
