A basic recursive random tree generator in 2D and 3D.

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

Transformation of drawing elements by coordinate transformation according to Helmert.

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.

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.

10 commands in a single click. Heads up Display for Autodesk® AutoCAD® & verticals.

Triangulation creates a SubDMesh, Polyface Mesh or 3D Solid from a set of points using a Delaunay triangulation algorithm.

Create dynamic cross-sections of the ground level.

Specify or import points from .shp or .csv files. Then review and edit the points in drawings or map the points to your own blocks.

This app makes drawing trial trenches easy and uniformly.

Move objects to viewport extents.

Locate any requested Kilometric Position (KP) on an Axis or calculate the KP that corresponds to a selected point in a drawing.

Import Survey Points and Linework into Autodesk® AutoCAD®.

Splice (divide) polygon into 2 equal smaller polygons.

The App is a very convenient way to bring back frozen, locked and other layers to active Mode (ON).

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

This application allows you to change the order of the vertices of the polyline.

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.
