This setup will install add-in tools for Autodesk® Civil 3D® 2019, 2020, 2021, 2022 and 2023.

Feature Line to Alignment (Free): 
Creates an Alignment and Layout Profile from a Feature Line or Survey Figure.

Parts Swapper (Free):
Allows for multiple Pipe Network parts (Structures and Pipes) to be swapped for alternative parts, simultaneously, by selection in Plan, Profile view, and by entire Pipe Network. 

Survey Sweeper (Free): 
Simultaneously delete selected Survey Points and Survey Figures from drawings and Survey Databases.

Corridor Cleanup (Free):
Select multiple Corridors, Baselines, or Regions, and in one click, remove all Surface, Width, and/or Slope Targets. 

Label Genie (Trial):
Automate labeling across projects, including Civil 3D and Autodesk® AutoCAD® annotation, on multiple drawings and layouts at once, in plan, profile or section. Save labeling templates for future use. 

Auto Grader (Trial):
Create dynamic site grading models by linking feature line sets. Surface breaklines are automatically managed. Save design templates for future use. 

Earthwork Processor (Trial):
Calculate complex site earthworks thru dynamic Civil 3D surfaces and automatically label, table, and shade results.  

Corridor Mapper (Trial): 
Automatically assign corridor targets by mapping subassemblies to layers, styles, object names or other subassemblies to create a dynamic link that updates the corridor as more target objects are created. 

Corridor Merger (Trial): 
Merge two or more Corridors into one, maintain all Targets and settings. 

Corridor Splitter (Trial): 
Splits a single Corridor into two.

Pipe Planner (Trial):
Edit and analyze pipe networks in external or in-app spreadsheets.

Pipe Designer (Trial):
Design pipe runs inside the Civil 3D drawing using a spreadsheet editor. 

Parts Tagger (Trial): 
Auto-populate one or more Pipe Network Part’s properties for Labeling or Tabling, including the following fields: Grate, Cover, Frame, Material, Rim Offset, Sump, Reference Surface, Reference Alignment, and Description. 

Sheet Generator (Trial): 
Sheet Generator is a multi-function, workflow-based solution for the creation and editing of Plan/Profile, Plan/Plan, or Profile/Profile sheets. 

Data Wizard (Trial): 
Data Wizard is a set of commands that help create AutoCAD spreadsheet tables from AutoCAD and Civil 3D entities.
