Civil 3D 2024 provides several improvements that make creating and managing infrastructure designs easier. If you’ve struggled with sharing/updating custom subassemblies in the past, you’ll find Civil 3D 2024 treats PKTs just like external references in that they can be attached or reloaded with a couple clicks of the mouse.
The Connector for ArcGIS is enhanced in 2024 to allow for the stylization of connected GIS layers based on attribution. Connected objects may also be brought in as AutoCAD entities if desired. If you’ve been taking advantage of the recent Corridor Transitions feature, you’ll find a new “lock” option in 2024 that makes it possible to slide transition sets back and forth along a corridor baseline.
If you're interested, I’ve uploaded some videos below that provide a practical run-through of each of these new features.
