Application to change the style of multiple pipes or structures to a user specified style that exists in the drawing. Capable of doing an entire network or selected parts only.

Calculates the elevations of two crossing pipes and inserts a leader with text showing the invert of the higher pipe and crown of the lower pipe.

Set the reference alignment of selected parts or entire network with one command.

DWG Columns freeware shows the DWG and DXF version in Explorer columns or in file dialog boxes within Autodesk® AutoCAD® or other applications.

Allows changing layer color of selected multiple objects without entering layer manager.

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.

A command to label the station ahead and station behind a vertex on polyline relative to an alignment PI. This command is useful when Civil 3D only presents for the station and offset label.

Extracts all of the boundaries from surfaces in the drawing.

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

Attempts to improve a field survey in certain cases by creating a smoothed out version of an original 3d polyline

A road design productivity tool to quickly visualize horizontal sight distance lines along a polyline alignment.

Generates successive polyline approximations of lwpolyline/polyline3d objects to smooth out the original shape but keep the overall polyline trend.

Morphs one polyline into another by generating intermediate polylines at arbitrary stages of the process.

A basic recursive random tree generator in 2D and 3D.

Create multiple surfaces from a selected Autodesk® Civil 3D® surface at precise elevations.

Arrange is a plug-in for Autodesk® AutoCAD® for arranging objects.

BOM Assigner & Exporter is an Autodesk® AutoCAD® tool which helps to get quick Bill of Materials in 2D architectural drawings.

Create shortcuts/bookmark to the xref files and set the properties of xref, so that later these xref's can be attached easily.

Quickly trace the boundary of selected objects. From selected objects(Line, Arc, Polyline), the app will trace and find out Closed Polyline in a second.

Inserting and Editing RasterImage is simpler than ever!

Quickly divide a closed polyline into smaller parts. A special tool for planning works.

Copy and Paste the group(s) between two drawings. Normally, when copying object(s) in group to another drawing, the group information will be removed. This tool will help you in this situation

A routine that puts the XY model space coordinates as text in the 4 corners of layout viewports.

TBN2CAD is a package of plugins for Autodesk® AutoCAD® to work with maps and images and also ease some design procedures.
