Chapter 1: Introduction 1.1 What is Subassembly Composer? civil 3d subassembly composer tutorial pdf

Visual authoring tool for custom subassemblies (PKT files). No coding required – uses flowcharts and math expressions. Output: Subassemblies that behave like Autodesk stock parts.

1.2 Why Build Custom Subassemblies?

Stock subassemblies don't fit local standards (e.g., unique ditch shapes, curb inlets). Conditional behavior (e.g., if slope > 5%, add a bench). Dynamic targeting (align to a polyline, profile, or surface). This outline includes the table of contents ,

1.3 Workflow Overview Draw typical section → Define points/links/shapes → Add logic → Set parameters → Export .PKT → Import to Civil 3D tool palette → Use in corridor.

Chapter 2: Interface & Basic Workflow 2.1 Main Panes (Screenshot descriptions)

Flowchart Workspace (center) – drag/drop visual logic. Toolbox (left) – geometry, math, decisions, lists. Properties (right) – input parameters, output parameters, geometry. Preview Pane (bottom) – 2D/3D preview of your subassembly. No coding required – uses flowcharts and math expressions

2.2 First Launch Settings

Set units: Metric or Imperial (critical – match Civil 3D drawing). Grid spacing: 1m or 3ft.
