See the previous Projects Updates section for the many Project Sandbox 2024 improvement details.

Mini-Project Datasets

The Framework for Civil 3D includes additional smaller Civil 3D Project Datasets focused on specific Civil 3D workflows and mechanics.
The Project Datasets are available for the default NCS 6.0 in STB at the minimum.

To fully support Windows 10 and Windows 11 compatibility the default Sandbox project location is:
C:\Users\Public\Documents\Autodesk\Civil 3D Projects.
All included Reference Template (TREF) and project-based File Dependent References target this install location by default.

Turn Lanes and Medians Project

The Medians Project Dataset explores Civil 3D Project Data Reference (DREF) method and practice to fully support Multiple Baseline Corridor design options.
Multiple design options are supplied including two shared design options and a separate grading Datum surface the employs a separate Set of Assemblies.
The project also explores use of Corridor Frequency Models to help produce faster deliverables annotation in Civil 3D.

The Corridor naming convention employed is documented with a PDF included in the dataset.
The Medians Project explores the Corridor creation and construction of a complex 4-way Intersection with Turn Lanes and Medians with nuanced Alignment and Profile design control.
The Medians Project explores the use of managed DREF (Data Reference) design control to employ multiple design, region, and assembly options in Multiple Baseline Corridor design and development.

The Medians Project:

Project named Medians-8-<Civil 3D Release>
The project employs a Reference Template (TREF)
The project employs multiple shared Data Reference (DREF) sources for the design control
Includes an initial Intersection with Median and Turn Lane design with Offset Alignment, Slope controlled Offset Profiles, and Curb Return design control and complex targeting
A Grading Corridor produced with Generic Pavement Subassemblies that employs the same design control to resolve a construction Datum surface
A second design option that resolves the same Intersection with a different Baseline Plan and different Set of Assemblies
Multiple example Corridor Frequency Models to resolve output Surfaces, Points and Labels, and validate and adjust the Region design control
Sample DREF Corridors and Feature Line annotative output is employed to produce Label Style Expression Set (LSES) Segment Label annotation for the design
By default, static extracted Corridor Feature Lines are employed to generate the Segment Label locations
Code(s) based Property Set Labels with variable Elevation truncation and optional Height of Curb Labels are employed

See the Civil 3D Turn Lane and Median Corridors post and video series for topics and details related to the Medians Project Dataset.

The dataset is tested and validated with the Autodesk Desktop Connector Reference Explorer tool.

See the Blog Videos page for videos and posts on Turn Lanes and Median Corridor topics and details.

Label Style Expression Sets Project

The Label Style Expression Set (LSES) Project Dataset explores the usage and mechanics of Framework for Civil 3D Labels in multiple grading annotation scenarios.
Included scenarios include typical and atypical Surfaces, multiple design Corridors for Ponds, Roads, and Parking Lot grading projects.

The Dataset explores the use of Framework Label Style Expression Set (LSES) resources with Variable and/or Fixed Truncation combined with Code(s) Property Set Label Style annotation to generate production deliverables annotation from these common Civil 3D grading scenarios.

Label Style Expression Sets Project:

Project named LsEs-8-<Civil 3D Release>
Employs multiple shared Data Reference (DREF) sources
Employs a Reference Template (TREF) and multiple Label Style Reference Templates
Example drawings employ either or both Variable or Fixed Truncated Contour LSES Labels
Current Layer, Variable Truncation, and Code(s) Property Set LSES Labels are typically employed
A Parking Lot example with LSES Labels produced on a live Corridor Model and Dynamic Corridor Feature Lines
A Roadway example with LSES Labels produced on a DREF Corridor Model and Dynamic Corridor Feature Lines
A Pond example with Surface Variable Truncation Spot Elevation and Contour LSES Labels produced on a DREF Corridor Model
A Site Design example with Surface Variable Truncation Spot and Contour LSES Labels produced on a complex DREF Surface Model produced by Grading Optimization

All Label Style Reference Template Style collections may be easily replaced with other supplied Label Style Expression Set (LSES) Style collection resource drawings.

The Dataset drawings may therefore be employed to develop LSES Label Style resource collections for customer production use.

The dataset is tested and validated with the Autodesk Desktop Connector Reference Explorer tool.

See the Blog Videos page for videos and posts on Label Style Expression Set topics and details.
