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

Replaces the last profile entity with the exact same profile entity. This provides a method to remove the extended portion of a profile after the extension.

The Express Document Tab program is a utility program that makes it easy to switch between DWG drawings in Autodesk® AutoCAD®.

Helps automate the conversion of a regular 2D polyline to an Autodesk® Civil 3D® profile and apply it to an existing Civil 3D alignment.

Draws markers at user selected locations along Autodesk® Civil 3D® Alignments, Profile Views, Sample Lines and Section Views.

Automatically creates an Autodesk®Civil 3D® alignment and profile from existing 3D polyline (3Dpoly) objects.

Automates the process of appending Autodesk® AutoCAD® polylines to existing Autodesk® Civil 3D® alignments, allowing polyline translations and checking/correcting sub-entity direction.

KeySurfaceFix allows you to find and repair holes in an Autodesk® Civil 3D® surface so that your surface more accurately reflects the existing site and design proposals.

Convert Spline Objects, Ellipse objects, Arc objects, Polyline-Arcs and Circles into vectorized objects based on user-defined segment length.
