The phrase "AutoCAD Civil 3D 2015 15" typically refers to the 2015 release of Autodesk's civil engineering software, where "15" likely signifies the internal version number or a specific update iteration within that year's cycle.

You can create feature lines either by drawing them from scratch or by converting existing geometry. Create from Objects (Recommended for existing layouts) tab on the Ribbon. Create Design panel, click the Feature Line dropdown and select Create Feature Lines from Objects Select existing AutoCAD lines, arcs, or polylines and press In the dialog box, assign the feature line to a autocad civil 3d 2015 15

• InfraWorks 360: The integration with InfraWorks (conceptual design software) was smoothed out. Users could bring a rough road layout from InfraWorks into Civil 3D 2015 for detailed engineering, and then push it back to InfraWorks for visualization, with fewer data translation errors.
• GIS Data: The FDO (Feature Data Object) connection tools were improved, making it easier to connect to ESRI SHP files and SDF databases, a critical requirement for planning large-scale infrastructure.

• Pressure Networks: The 2015 pressure network engine was stable. Later versions (2016-2018) had horrible regression bugs with fittings.
• Corridor transitions: The baseline region transition logic in 2015 is predictable. It doesn't have the "frequency override crash" that plagued 2016.
• Performance on old hardware: This version loves a fast single-core clock speed. It ignores your GPU for most tasks.
