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

Generates an Autodesk® AutoCAD® Tool Palette with buttons that correspond to the current drawing's object/label styles. Click button to apply style.

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

Quickly isolates a range of contours by setting up the user contour analysis for a range of elevations.

Productivity Tools for Surfaces and Profiles.

Generates an Autodesk® AutoCAD® label of a selected surface's statistics.

Toggles various surface plan/model view display components from the command line.

Traces profile with a polyline between selected stations.

Applies an object style to multiple objects at once. This app allows you to quickly apply a style to several objects at once.

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.

Performs find and replace on a number of Autodesk® AutoCAD® Civil3D® Object type's Names and Descriptions.

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®.

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.

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.

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

Easily model spill-cone-shaped surfaces, update the original surface and compute volumes in Autodesk® Civil 3D® with dynamic preview of the results.

It is a custom hatch pattern editor for CAD hatch fills.

Dynamically draws diagrams on Autodesk® Civil 3D® tin surfaces to help visualize possible directions from a given point within preset grade limits.

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

Generates successive polyline approximations of lwpolyline/polyline3d objects to smooth out the original shape but keep the overall polyline trend.

The application provides a powerful tool for calculating Earthwork Volume values and creating Earthwork Plan

GeoToCAD™ demonstrates options for establishing a bi-directional connection between Autodesk® Civil 3D® and ArcGIS®, a geospatial platform.
