Toggles the surfaces in a drawing to a non-display style from a display style.

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.

Creates an average surface slope report based on the contour lengths and an average surface slope report based on contour lengths by slope ranges.

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.

A simple 2D maze generation app. It can also be used to generate random hatch patterns.

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

A recursive Hilbert fractal space-filling pseudo curve generator in 2D/3D

Automatically update Autodesk® AutoCAD® title block attributes from a Microsoft Excel spreadsheet.

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

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

Convert Wavefront Technologies OBJ (or .OBJ) files to Mesh3D entities.

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.

Animation GIF Maker is a utility that makes it easy to animated-gif on the Autodesk® AutoCAD® working screen.

This application will allow you to create different kinds of doors from "single, double panel, bifold communicating pass through and so on."
