Designers gained granular control over station frequencies along tangents, curves, spirals, and profile verticals.
Corridor modeling is the backbone of linear infrastructure in Civil 3D. Version 2015 introduced highly requested subassembly and targeting enhancements:

If you are upgrading from Civil 3D 2013 or 2014, the ribbon interface in 2015 will feel familiar, but smarter. Version 15 introduced that only appear when you select a specific object. For example:
AutoCAD Civil 3D 2015 was built on the AutoCAD 2015 database format. It introduced significant graphic engine upgrades and shifted entirely away from 32-bit architecture to maximize modern hardware utilization. Hardware Prerequisites
This "15" version was the last of its kind to support 32-bit operating systems (though 64-bit was recommended). It was also the first version to fully standardize the structure, which became the backbone of later InfoWorks and InfraWorks integration. Create from Objects (Recommended for existing layouts) tab

Unlike later versions that demanded SSDs and high-end GPUs, Civil 3D 2015 ran respectably on Windows 7 workstations with spinning hard drives and 8GB of RAM. For small firms or field laptops, this was a lifesaver. Regens were slower, but crashes were rarer—a trade-off many still accept.
You can show hard 3D shapes directly on your profile views. Computer System Requirements
