Allow your custom links to stretch and morph to hit specific horizontal alignments, feature lines, or 3D polylines, as well as vertical profiles and existing terrain surfaces. 2. Understanding the Interface

In the Subassembly Composer, you will see a 3D model of the subassembly. You can now define the subassembly parameters, such as the lane width, shoulder width, and curb height. To do this, click on the "Parameters" tab and enter the required values.

In the Expression field, write an IF/THEN statement. For target checking, use: BaseSurface.IsValid . civil design 3d subassembly composer tutorial pdf top

The is an essential tool for Civil 3D users who need to create custom corridor components that exceed the capabilities of out-of-the-box subassemblies. This guide provides a structured overview of the workflow, interface, and best practices for mastering SAC to build smarter, more flexible civil designs. Getting Started with Subassembly Composer

Select P2 and add "Top" , "Crown" , or "ETW" (Edge of Travelled Way) in the Point Codes field. Always wrap codes in quotation marks (e.g., "Top" ). Allow your custom links to stretch and morph

: The configuration panel where you define exact coordinates and math.

Are slopes explicitly designated as Slope or Double types to avoid unit conversion bugs? You can now define the subassembly parameters, such

You can download the PDF directly from the FDOT CADD Office website. The guide also includes accompanying dataset files and video modules available via YouTube links.

Start with the fundamentals—understanding the five interface panels, creating your first fixed-geometry subassembly, and learning proper coding conventions. Progress to dynamic behavior with input parameters and targeting, then graduate to conditional logic and API expressions. Along the way, leverage the best practices of clean flowchart organization, strategic decision elements, and thorough testing in Layout and Roadway modes.

Defines the specific attributes of the selected element (e.g., Code, Geometry). 2. Fundamental Concepts: Points, Links, and Shapes
