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

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

Catenary is the curve of an idealized free hanging cable supported at its ends. This app provides several commands to draw this U-like shape in Autodesk® AutoCAD® utilizing different input parameters.

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

Automatically creates an Autodesk®Civil 3D® alignment and profile from existing 3D polyline (3Dpoly) objects.

Helps automate the conversion of a regular 2D polyline to an Autodesk® Civil 3D® profile and apply it to an existing Civil 3D alignment.

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

Draws markers at user selected locations along Autodesk® Civil 3D® Alignments, Profile Views, Sample Lines and Section Views.

Procedural random infinite tin surface terrain generator for Autodesk® Civil 3D®.

Simple command line interface for adding Autodesk® Civil 3D® Cogo points to a point group.

Renumbers fragmented cogo points inside a point group to eliminate gaps in point numbers. The end result is a point group with sequential numbers.

Helps identify and select possible duplicate cogo points in a Autodesk® Civil 3D® drawing.

The Sokoban plugin allows you to play the classic Sokoban game inside Autodesk® AutoCAD®!

Watson6.0 by Watsonlisp.com is an artificial intelligence referencing agent written in autolisp and visual basic. Watson finds detail drawings by text and attribute content!

pmxExportKML is a plug-in for Autodesk® Civil 3D® and Autodesk® AutoCAD® Map that exports Autodesk® AutoCAD® and FDO (Feature Class Objects) objects to a KML.

Creates an Autodesk® Civil 3D® TIN Surface below an Autodesk® AutoCAD® solid entity that cuts through the surface.

Generate an Autodesk® AutoCAD® polyline from an Autodesk® AutoCAD® Civil 3D® pipe network.

SmartDraft HEC-RAS Tools are an excellent set of tools to exchange data between Autodesk® Civil 3D® and HEC-RAS.

SmartDraft: Inverse Points provides a tool for inverse between point objects, point numbers, or Autodesk® Civil 3D® Survey database points.

Confirmed to work with the leading slope stability software, this app automates the export process of profiles to DXF format for importing into slope stability software.

Tools for quickly modifying pipe slopes and elevations.

Changes colors of entities in a drawing to any other color.

Connects Autodesk® AutoCAD® with Google Earth and the Real World.
