Easily track changes you and others make to drawings in your project. Keep a history of local edits as an individual, or through a central worksharing location. From history, you can view and compare.

Moves/copies/stretches object to the calculated intersection point of lines. The user would normally have to construct to define that point.

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

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

Extends the picked end of an object (or last segment) to the picked destination point in a direction parallel to the object.

Filters selected objects by desired object types, layers, colors, blocks, linetypes, lineweights, linetypescales, or text content of MTEXT and TEXT objects.

Import & export objects, images, terrain meshes, and 3D models between Google Earth ™, SketchUp ™, and Autodesk® AutoCAD®.

LRailplan is a professional railway route design software. It is an all-in-one solution for the integrated process of railway alignment design, enabling you to design with skill and ease.

A fast, search and navigation tool for Autodesk® AutoCAD® sheet sets. Instantly find, filter, and manage sheets and drawings with ease.

Toggle instant presentation and edit modes in Autodesk® AutoCAD®. Focus your workflow and reduce layer clutter with a single click.

This application filters and selects objects with the same shape in the drawing.

Square off those crooked survey building outlines with a single mouse click.

Real-time quantity and cost estimating inside Autodesk® AutoCAD® and Autodesk® Civil 3D®. Map layers to rate library items and see construction costs update live as you design.

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

A set of dynamic tools to work with Clothoid transition curves in Autodesk® AutoCAD®.

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

Calculates the Total Length/Area of multiple objects of selected type(s). Inserts labels and specifications of the selected objects.

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

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

Calculate total length of different entities, filter by layer or color

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