App for Autodesk® AutoCAD® makes it easy to create or draw a catenary curve as a polyline by specifying the start and end point and the length/immediate point/sag and optionally a diameter(width).

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.

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.

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

A seven-parameter similarity transformation calculator in 3D space.

Very fast Labeling of polylines or XRef's containing polylines for Autodesk® AutoCAD®

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

This plugin helps you to create a Bunch of Polylines by selecting the start and end points, and drawing a single main polyline.

Cables and Connectors Catalogue is a program containing information about broadcasting cables and connectors.

This software helps to easily add, scale, edit and remove images with description on the drawing.

Length, area, volume. Select, calculate, copy to clipboard, insert combined with any text as plain text, field, table, (dynamic) block, or simply export to TXT, CSV or JSON file.

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.

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

Animate history of drawing objects.

Draws normal (perpendicular) vectors of 3D Faces, finds backfaces, flips 3D Faces (front/backface).
