Allows changing layer color of selected multiple objects without entering layer manager.

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

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

A road design productivity tool to quickly visualize horizontal sight distance lines along a polyline alignment.

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.

Arrange is a plug-in for Autodesk® AutoCAD® for arranging objects.

Create shortcuts/bookmark to the xref files and set the properties of xref, so that later these xref's can be attached easily.

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.
