Populate polyline areas to block's attributes.

DWG/DXF Compare plugin compares two drawing files and the comparison result is shown in a new Autodesk® AutoCAD® window.

Sums lengths/areas and copies them to the clipboard.

Selects all objects of the same layer / block name / object type / color as the selected object(s).

Program to easily change the layer name or name of the selected block.

Inserts text from the clipboard to the selected TEXT, MTEXT, MULTILEADER, ATTRIBUTE, or ATTRIBUTEDEFINITION TAG.

Searches for text content given by the user and selects matching objects.

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

It creates a new layer with the same properties as the layer of the selected object.

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

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 app helps to export your drawing files' names which are of .dwg format to a text file.

Offset 2D entities with different distances at once.

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

Create and assign numbers to intersections between 2 Polylines/Lines/SPLines groups. Insert block/point/text objects at intersections—export results to Excel worksheet.

Copy, rotate objects in an array-like way. Break purlins lines to show lappings in few clicks.

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

Unfolds sheet metal elbows and cylindrical segments. A segment is part of a cylinder intersected by two arbitrary planes.

Sheet metal pipes need shaped elements. Three types are presented here: transition from rectangular to circular section, straight reducing cone, and eccentric reducing cone.

Obtaining the section or unfolding ( developing ) of a cone intersected by a plane or the unfolding ( developing ) of a winding of a conical or cylindrical shnek is used.

Ceethreedee Free tools for Autodesk® Civil 3D®. Batch Create stuff / extracting strings from surfaces / and more!

A tool for smart and simple geometric modeling of pipe networks. Using it, you can import networks to AutoCAD®, create longitudinal profiles, check crossing points, and export BIM models very quickly.

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

Interactively positions text characters along lines, polylines, splines, circles, arcs, and ellipses.
