Civil 3D 2022 New Feature - Connected Alignment with offsets

You can use the connected alignments feature to create an alignment that transitions between two intersecting alignments and to create a profile that transitions between their profiles.

You can use this feature to create a curb return, an exit ramp, a merging/diverging road, or you can connect an existing road with a proposed road. You can also create complex curve groups to support interchanges, and apply offsets from the parent alignments to support off-ramp scenarios. You can create connected alignments less than 180 degrees or greater than 180 degrees.

The connected alignment is created between the two intersecting alignments using specified parameters in the Create Connected Alignment dialog box.

The geometry of the connected profile is automatically generated from the parent profiles that you select. You can specify a delta elevation or a cross slope to control how the connected profile is generated at the overlap parts of the connected alignment (which are parallel to the selected parent alignment profiles). The start and end elevations and slope of the connected profile are taken from the overlapping parts of the parent profiles, and the middle section of the connected profile is calculated depending on whether and how the extensions of the parent profiles intersect.

New features for Civil 3D 2022 include the expanded capabilities of the connected alignment workflow, particularly for complex intersections and interchanges.  

When selecting intersecting alignments, users have a broader range of geometric options for the connecting alignment. The new connected alignment solution supports complex curve groups, offsets from parent alignments, curves larger than 180-degrees, and calculates the crossfall of the associated profiles. This tool puts greater control into your hands for interchange design.  Learn more in the video below.
