What are Feature Lines?br Feature lines are 3D lines that represent linear features, such as:br br 1. Roadsbr 2. Pavementsbr 3. Channelsbr 4. Ditchesbr br Creating Feature Linesbr 1. Create Feature Line Tool: Access the "Create Feature Line" tool.br 2. Draw Feature Line: Draw the feature line in the drawing area.br 3. Define Elevation: Define the elevation of the feature line.br br Editing Feature Linesbr 1. Edit Feature Line Tool: Access the "Edit Feature Line" tool.br 2. Modify Geometry: Modify the geometry of the feature line.br 3. Adjust Elevation: Adjust the elevation of the feature line.br br Feature Line Applicationsbr 1. Road Design: Design roads, highways, and other infrastructure.br 2. Site Design: Design site features, such as pavements and channels.br 3. Stormwater Management: Design stormwater management systems.br br Benefitsbr 1. Accurate Design: Create accurate 3D designs.br 2. Improved Visualization: Visualize designs in 3D.br 3. Enhanced Analysis: Analyze designs for performance and compliance.br br Tips and Variationsbr 1. Use feature line styles: Apply consistent formatting and appearance.br 2. Use feature line labels: Label feature lines with relevant information.br 3. Integrate with other Civil 3D tools: Use feature lines with other Civil 3D tools, such as surfaces and corridors.
