Plot to a pre-specified printer with one pick. A, B, C, D, E sizes and PDF (Plot Window with 3 Picks) for Autodesk® AutoCAD®. Now with available Preview.- Saves Paper

The FREE plugin for Autodesk® AutoCAD® to get Google Earth imagery right into your drawings!

Custom hatch pattern editor for CAD hatch fills.

Show the DWG and DXF versions and properties and metadata in Explorer columns or in file dialog boxes within Autodesk® AutoCAD® or other applications.

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

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.

Tools to unfold 3D model

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.

Lisp allows continuing drawing Polyline, 2D polyline, 3D Polyline, MultiLine, or Line starting from the selected end.

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