Archive, analyze, modify, or create drawing entities in a CSV environment using tools like Excel, Calc, or Notepad!

Dynamically annotate coordinates along the path of a variety of Autodesk® AutoCAD® 2D and 3D objects.

Convert one or more 3D polylines into 2D polylines and vice versa.

This routine makes perfect to select all Blocks or one by one on a Polyline and rotate them after Polyline direction. Also, you can change the Position of the Attributes up or down the Polyline.

This tool can be used to display and edit XDATA detail of selected entity.

Synchronously view and compare multiple drawing document or multiple model viewports side by side.

An application to help you get a deeper understanding about the Autodesk® AutoCAD® system variables

This app helps you save a lot of time to select objects by quickly making filter and quickly selecting similar objects based on sample entities.

3 tools in 1 app. The easiest way to get total Area and Length or Perimeter of objects. Export result to clipboard or put to text objects

Quick DTM tools for creating TIN, fitting breaklines, creating and managing 3D surfaces, generating and labeling contours, basic watershed analysis, and creating quick sections. 30-day trial period.

Joins and cleans-up polylines and line entities to create closed boundaries and to close gaps not seen visibly.

Creates multiple-types of 3D screw and/or fastener hardware with a variety of head types in Imperial and Metric units. It comes with built –in post processing tools for block modifications.

Joins adjacent polyline, line and arc segments to create (or convert selected line objects) into closed polyline objects

Creates multiple-types of 3D screw and/or fastener hardware with a variety of head types in Imperial units.

Creates a 2D or 3D spring object from user-input; Height, Pitch, Diameter and number of Coils

Searches the minimum distance in a design, finds design errors, and will flag on-screen plus list the minimum distance value and X/Y coordinates

Display the degree angle of selected LINE or POLYLINE entities in either Decimal or Minute values based on a selected ‘base line’

Parametrically creates a radial type grid useful for drafting needs that require precise angular grids.

Adds a vertex to polyline segment(s) and snaps it to a specific degree angle, to one of: 10, 12, 15, 30, 45, 60 or 90 degrees

3 Function App to create multiple layer groups to turn on one group/Batch and turn off others

Checks for and identifies closed polylines with outward or inward facing acute angles (less than 90°) and draws pointers

This program calculates the offset distance of multiple points to a straight line consisting of an alignment (polyline). Handles easily 1000k points in .txt formats.

The leading PDF to DWG converter designed specifically for Mac OS X

Predecessor to a much more ambitious program, this app provides 20 artistic landscape blocks for free.
