The Land[x] stair plug-in provides tools for creating and editing simple solid staircases in Autodesk® Civil 3D® based on parameters for height of riser, length of tread, width, landing and slope.

Productivity tools for Pipe Networks.

Creates a 3D polyline at a desired grade or slope along a tin surface.

Corridor multiple targets (CMT) is an add-in tool for Autodesk® Civil 3D®. This tool attempts to simplify targeting of complex corridors using text filters and using modelspace entity selection.

Import & export objects between Google Earth™ and Autodesk® AutoCAD®

Plugin for design urban drainage and sewage systems.

Program for calculating the distribution of earth moving in linear works

Spatial Manager™ for Autodesk® AutoCAD® is a powerful AutoCAD plug-in designed for AutoCAD users who need to import, export and manage spatial data in a simple, fast and inexpensive way.

Recursively generates all possible lines along an Autodesk® Civil 3D® surface from a given start point having a specified grade.

このプログラムを利用すると、日本の設計図書作成の効率化が図れるだけでなく、日本固有のファイル形式の読み込み／書き出しができます。本Update1より、国総研交換標準読み込みツールを統合しました。

Easily convert those old leaders and text to Mleaders!

AU Pricing!! Never forget why or where you snapped a project photo. PhotogeoDWG automatically imports photos to the location and orientation they were taken.

Generates successive polyline approximations of lwpolyline objects to smooth out the original shape but keep the overall polyline trend.

Utility for moving, aligning and copying text. Also has the ability to create new text labels.

Create surface profiles of many alignments with one click.

This tool allows you to create spot elevation labels and slope labels on a grid which is aligned to your selected alignment or polyline.

Offset 2D entities with different distances at once.

Automation development according to GOST.

Automate the batch insert of raster images.

MatchProfiles is a plugin for Autodesk® AutoCAD® Civil 3D® that allows users to quickly match the configuration of different profile views.

This command moves each vertex of 3DPolyline to blocks z position when vertex and the block has the same X and Y coordinates.

TotalBoundary easily generates outlines of complex drawings.

Replaces the last profile entity with the exact same profile entity. This provides a method to remove the extended portion of a profile after the extension.

This will help in creating an Autodesk® Civil 3D® Profile based on the vertices of the 3DPolyline.
