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

Attempts to improve a field survey in certain cases by creating a smoothed out version of an original 3d polyline

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.

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

Some special commands to work with polylines.

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.

Inserting and Editing RasterImage is simpler than ever!

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

Zero Level Pro plugin for Autodesk® AutoCAD® is designed to benefit users for calculating the vertical section levels in all engineering fields to save time and effort and give more accuracy.

This plug-in can be used with Autodesk® AutoCAD® to quickly collect the area and length of a group of selected polylines grouped by layers.

Easily convert those old leaders and text to Mleaders!

Pick on a drawing entity and place text in the drawing listing the entity's area.

ID a point on the screen and label it with a Mleader.

Identify Northing and Easting of a point on the screen

QuickAreas is a handy add-in for Autodesk® AutoCAD® that retrieves the area property of multiple polylines and inserts a label with its associated area value.
