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.
