Use the tool to create smart components. A decision expression evaluates a condition as True or False. For example, you can write an expression to check if a point is in a "Cut" or "Fill" situation relative to the existing terrain surface. The flowchart then branches into two distinct design paths based on the result.

As you advance, you can leverage features like and decisions to create conditional logic (e.g., "if slope is greater than X, then add a bench"). You can also use API functions and mathematical expressions to calculate parameter values on the fly, creating incredibly responsive and intelligent designs. A decision expression evaluates a condition as True or False

Always design your subassembly for either the Left or Right side using the standard Side parameter. Civil 3D will handle the mirroring automatically when you use the "Mirror Subassembly" tool in your drawing workspace.

Because this is a comprehensive, publication-ready guide, standard article formatting is used below to ensure deep, technical coverage of the topic.

Set it to Slope and Delta X with a fixed width as a fallback mechanism so the corridor does not crash if the surface target is temporarily lost. Step 5: Enclosing the Shape
