If : Execute the Fill branch (slope directly down to the ground surface). Superelevation Integration
Contains the building blocks (Points, Lines, Shapes, Decisions, and Switches) that you drag and drop into your design.
Sometimes a general search for a "tutorial PDF" may yield limited results. For the most effective learning, try using these specific search strategies:
The engine room where you define variables, input parameters, and target surfaces. 3. The Core Building Blocks: Points, Links, and Shapes civil 3d subassembly composer tutorial pdf
A real-time visualizer. It features two modes: Roadway Mode (shows how it behaves in a corridor) and Layout Mode (shows how it appears on a tool palette).
Displays mathematical formulas, point codes, and specific variables for whichever item is selected in the Flowchart.
Setting up components to look for surface, width, or elevation targets in your corridor model. If : Execute the Fill branch (slope directly
Drag a standalone tool from the Toolbox to close the loop.
Let's walk through building a standard parametric curb and gutter subassembly.
Most official or high-quality training PDFs provide accompanying exercise files, allowing you to follow along step-by-step. For the most effective learning, try using these
Before dropping geometry, navigate to the tab and define your variables so users can adjust them later: GutterWidth (Type: Double, Default: 1.5 ft) CurbHeight (Type: Double, Default: 0.5 ft) CurbWidth (Type: Double, Default: 0.5 ft) GutterSlope (Type: Slope, Default: -2.0%) Step 2: Build the Gutter Link
(Type: Double, Default: 3.6m). This allows users to change the width later in the Civil 3D Properties palette. Target Parameters: Create a "Surface Target" named ExistingGnd to allow your subassembly to "find" the ground. 3. Building the Logic (The Flowchart) Construction always starts from the Origin (0,0) , which represents the Attachment Point on your Assembly. Step A: Creating Points (P) into the flowchart. is automatically at (0,0). Drag a second point ( ). Set its geometry type to Slope and Delta X Use your parameter for the Delta X and a slope value (e.g., Step B: Creating Links (L)
