Add subassemblies to a drawing using the subassemblies provided through the AutoCAD Civil 3D tool palette or tool catalog, or create your own custom subassemblies.
When using the preconfigured AutoCAD Civil 3D subassemblies, adding the subassembly to the drawing creates the subassembly object.
If you want to draw a custom shape and use it as a subassembly, use the Create Subassembly from Polyline feature. For more information, see Creating Subassemblies From Polylines.
Another approach to creating customized subassemblies is using the Autodesk Subassembly Composer for AutoCAD Civil 3D. This method provides you with the ability to create custom subassemblies with simple or complex conditional behavior built in. For more information, see Creating Custom Subassemblies.

- Creating Subassemblies From Polylines
You can create customized subassemblies from AutoCAD polyline objects in a drawing.
- Inserting Subassemblies on Right and Left Sides of a Corridor
Some subassemblies use a Side input parameter to specify inserting the subassembly on the right or left side of a corridor; other subassemblies allow you to do this by specifying a positive or negative value for the insertion point input parameter.
