Generates successive polyline approximations of lwpolyline objects to smooth out the original shape but keep the overall polyline trend.

Recursively generates all possible lines along an Autodesk® Civil 3D® surface from a given start point having a specified grade.

Procedural random infinite tin surface terrain generator for Autodesk® Civil 3D®.

Simple command line interface for adding Autodesk® Civil 3D® Cogo points to a point group.

Creates an Autodesk® Civil 3D® TIN Surface below an Autodesk® AutoCAD® solid entity that cuts through the surface.

Exports surface analysis and corresponding properties to an *.anl text file. Imports text file and applies new surface analysis with inherited properties to selected surface.

Confirmed to work with the leading slope stability software, this app automates the export process of profiles to DXF format for importing into slope stability software.

Creates a 3D polyline at a desired grade or slope along a tin surface.

Polyhedral Mesh to Solid is for that difficult Mesh, which won’t convert to 3D Solids because of self-intersecting faces etc. It also locates the Center of Mass for a single or a group of objects.

TBN2CAD is a package of plugins for Autodesk® AutoCAD® to work with maps and images and also ease some design procedures.

Draws normal (perpendicular) vectors of 3D Faces, finds backfaces, flips 3D Faces (front/backface).

Productivity tools for Pipe Networks.

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

Carlson Connect is a collection of routines for transferring and converting data between Autodesk® Civil 3D® and Carlson Software applications.

Carlson Connect is a collection of routines for transferring and converting data between Autodesk® Civil 3D® and Carlson Software applications.

Move polylines to an elevation value stored in an Object Data field.

This tool allows you to create spot elevation labels and slope labels on a grid which is aligned to your selected alignment or polyline.

Generates 3D model from cross-sections and unfolds it into flat pattern.

Automates the geometric design of stormwater ponds in Autodesk® AutoCAD® Civil 3D®.

This tool allows you to add labels to all contours more easily.

Extract multiple “child” surfaces from an existing surface by selecting polylines that define their outer boundary.

Calculates the average of spot surface elevations labels. It also allows the user to add or subtract a constant value to the calculated average.

This command moves each vertex of 3DPolyline to blocks z position when vertex and the block has the same X and Y coordinates.

Toggles the surfaces in a drawing to a non-display style from a display style.
