The connected alignment functionality has been enhanced to better handle complex geometry for ramps and interchanges.
- The following enhancements have been made to the connected alignment functionality:
- Several new alignment curve group combinations have been added, supporting combinations of spirals, curves, and reverse spirals.
- Support has been added for creating curves greater than 180 degrees.
- Connected alignments can now be created at offsets from parent alignments to support slip lane and off-ramp scenarios.
- A preview option is now included so that you can preview the solution in the drawing before creating the connected alignment.
- If a solution cannot be found using the parameters that you input, you can create an auto-fit connected alignment.
For more information, see To Create Connected Alignments.
- Several new alignment curve group combinations have been added, supporting combinations of spirals, curves, and reverse spirals.
- The following new curve group types are now available when creating alignments with the Alignment Layout toolbar:
- Free Reverse Spiral-Curve-Spiral-Spiral (From entity, end curve)
- Free Reverse Spiral-Spiral-Curve-Spiral (From curve, end entity)
- Free Reverse Spiral-Spiral-Curve-Spiral-Spiral (Between two curves)
For more information, see To Add Complex Free Reverse Spiral Curve Groups to Alignments.
- A new command named Convert to Fixed has been added which converts an alignment with a curve group to fixed geometry. Use this command on an alignment with a curve group so that it can be edited in a previous release of the application. For more information, see To Convert Alignment Curve Groups to Fixed Entities.
