Avoid spaces or special characters in variable names. Use camelCase or underscores (e.g., laneWidth or Lane_Width ).
Subassembly Composer is a utility that comes with AutoCAD Civil 3D, which enables users to create custom subassemblies for use in corridor design. A subassembly is a collection of components that work together to form a part of a corridor, such as a road, highway, or railway. Subassembly Composer allows users to create custom subassemblies by defining the components, their relationships, and their behaviors. Civil 3D reads point, link, and shape codes
Connect P5 back to P1 by dragging a tool into the Flowchart. Set its properties from P5 to P1 (creates L5 ). Step 6: Define the Shape Drag a Shape tool into the Flowchart.
