SmartDraft: View Tools provide an excellent set of productivity tool to twist the view, control the crosshairs, and create and manage viewports.

Stationing polyline. Draw station lines on every vertex. Add station offset labels at specified points or selected objects along the selected polyline.

Break entities into different pieces based on different options. (e.g. specified points, intersection, specified distance, and equal parts).

Offset 2D entities with different distances at once.

Dynamic block that makes drawing reinforcement sections easier. Not transparent.

Rebar Distribution is a dynamic block for Autodesk® AutoCAD® that makes it easy to display custom length, pitch, diameter and distribution length of reinforcement bars.

OneNote Add-in for Autodesk® AutoCAD®. Take notes right alongside your drawings!

3D Stretch of solids

Draw 19" or 10" rack furniture, create drawings with patch panels, and place the panels into the rack furniture in a few clicks!

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

Edit layer, color, rotation, height, style, justification, value, case, position, reverse, width factor, oblique angle, and vIsability of attributes by tag or ALL in selected blocks.

One-click insertion of labels with name, number, area and perimeter of rooms. Values in a label are associated with the drawing and are automatically updated. Automatic insertion of Room Schedules.

GeoCode performs geocoding and reversed geocoding - it creates street address or what3words codes for picked points (location) and converts full addresses to lat-long coordinates and geomarkers.

One-click insertion of a block labeling absolute and relative elevation. The values in a label automatically update when the block is moved.

SERI Traffic Signs & Earth allows you to insert traffic signs, pedestrian crossings and import images from BING into your design. Automates the process of creating detailed traffic signs plans.

This program introduces two new 3DSolid edition commands: STRIM that subtracts overlaps without deleting the trimming solid, and SSPLIT that creates separate solids out of any overlapping portion.

This plug-in helps to remove the unused DGN LineTypes, TextStyles, RegApps and Annotation Scales and other Purgeable items from the current drawing or multiple drawings in batch processing.

This plug-in allows you to insert scannable Quick Response (QR) Codes into Autodesk® AutoCAD® drawings.

CAD Monkey Lite automates the process of creating and linking multiple drawings together.

The FacetCurve plugin can be used to facet 2D and 3D curves in AutoCAD® to approximate their curvature with a number of straight line segments. The faceted output is in the form of a number of lines

Time-proven way of 3D modeling piping systems with ease. Use a CAD library of more than 3,500 essential blocks (pipes, fittings, valves, etc.).

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

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.
