How to Use Subassembly Composer for AutoCAD Civil 3D: A Step-by-Step Tutorial
Subassembly Composer is a tool that allows you to create and customize complex subassemblies for corridor modeling in AutoCAD Civil 3D. Subassemblies are the building blocks of corridors, which are used to model roads, railways, bridges, tunnels, and other linear features. Subassembly Composer lets you design subassemblies visually, using a flowchart and a preview panel, without any programming knowledge required. You can also define targets, parameters, codes, and conditional behavior for your subassemblies. In this tutorial, you will learn how to find and install Subassembly Composer, how to create a simple subassembly project, and how to import it into Civil 3D.
How to Find and Install Subassembly Composer
Subassembly Composer is available as part of the installation of AutoCAD Civil 3D. To install it, follow these steps:
For version 2022: In Windows Control Panel > Programs and Features, click Autodesk Civil 3D 2022 and select Change. Make sure Subassembly Composer 2022 is selected in the component list[^2^].
For versions 2021 and earlier: Run the Civil 3D installer (Setup.exe) for the affected version. Note: Setup.exe is contained in the installation folder, extracted by default in : C:\\Autodesk\\Autodesk_Civil_3D_20xx_English_Win_64bit_dlm If the folder is not longer available, download the application from your Autodesk Account and extract it again. Click Install and accept the Terms and Conditions. In the installation window, under Install > Configure Installation, expand the drop-down arrow to access the settings of the installation. Select the box for Autodesk Subassembly Composer. Click the arrow again to close the section. Proceed with the installation[^2^].
How to Create a Simple Subassembly Project
In this section, you will create a simple subassembly project that consists of a basic road cross-section with a lane, a shoulder, and a ditch on each side. To create a subassembly project, follow these steps:
Open Subassembly Composer from the Windows Start menu or from the Civil 3D ribbon.
Use the Civil 3D menu bar to create a new subassembly project.
In the Settings and Parameters panel, specify the name, description, icon, input/output parameters, and help documentation for your subassembly.
In the Tool Box panel, drag and drop geometry elements from the Basic category onto the Flowchart panel. For this example, you will need four points (P1-P4), four links (L1-L4), and two shapes (S1-S2).
Select each geometry element from the Flowchart panel, and modify its properties in the Properties panel. For this example, you will need to specify the coordinates, codes, offsets, elevations, slopes, widths, depths, materials, and fill patterns for each element.
In the Preview panel, check the geometry of your subassembly and simulate how it behaves with different target values and conditions.
Save your project as a PKT file using the menu bar or the toolbar.
How to Import a Subassembly into Civil 3D
Once you have created and saved your subassembly project as a PKT file, you can import it into Civil 3D and use it in your corridor models. To import a subassembly into Civil 3D, follow these steps:
Open Civil 3D and create or open a drawing.
In the Tool Space panel, right-click on Subassemblies and select Import Subassemblies.
Browse to the location of your PKT file and select it.
Click Open to import your subassembly into Civil 3D.
Your subassembly will appear in the Tool Space panel under Subassemblies > Imported.
You can now drag and drop your subassembly onto an assembly in your drawing or create a new assembly with it.
Congratulations! You have learned how to use Subassembly Composer for AutoCAD Civil 3D. You can now create your own ec8f644aee
