Features and Benefits

The Autodesk Subassembly Composer for Autodesk AutoCAD Civil 3D provides an interface for composing and modifying complex subassemblies, without a need for programming.

Subassembly developers can compose complex subassemblies visually, using a powerful yet easy-to-use interface:

• Define the behavior of a subassembly using an easy to understand flowchart.
• Drag and drop common geometry elements and conditions from the categorized a tool box onto the flowchart.
• See a preview of the subassembly geometry, and simulate how the subassembly behaves with different target values and conditions.
• Find and edit the properties of a subassembly element using the synchronized flowchart and preview.
• Attach help documentation to the subassembly.
• Save subassemblies as PKT files. The PKT files can be imported into AutoCAD Civil 3D, which automatically generates ATC files.

The Autodesk Subassembly Composer for Autodesk AutoCAD Civil 3D provides a strong set of subassembly functionality for corridor modeling:

• Define points using several methods.
• Define links between points.
• Define shapes surrounded by links.
• Define advanced geometry elements, such as curves, fillets, and intersection points.
• Get and set marked points.
• Define auxiliary geometry elements as a basis for other subassembly geometry elements.
• Assign point, link, and shape codes.
• Define targets and input/output parameters.
• Organize geometry elements, or add conditional behavior.
• Define and set variables.
• Define complex logic with expressions and API functions.
