Add entities that contain curves and transition spirals.
This entity type can only be added to existing fixed or floating lines.
After clicking a button on the Alignment Layout Tools toolbar, follow the command prompts on the command line.
You can use transparent commands when you are prompted to specify direction, radius, or length, or use station offsets to specify any points. For more information, see Transparent Commands.
Tutorial Exercise: Adding Free Curves and Spirals to an Alignment
Topics in this section
- Adding Floating Curves with Spirals
Add floating curves with spirals in situations where you need a transition spiral and the curve geometry must pass through a specified point.
- Adding a Floating Reverse Curve with Spirals to a Curve
Add a floating reverse curve with spirals in situations where you need two back-to-back reverse transition spirals and the curve geometry must pass through a specified point.
- Adding Spiral-Curve-Spirals
Add a free spiral-curve-spiral group between two entities.
- Adding Complex Free Curve Groups Between Tangents
Use the Alignment Layout Tools to add complex curve groups to your alignment. Complex curve groups consist of multiple curves and spirals and are available in compound and reverse solutions.
