This AI assistant works like a chat partner in C3D, helping engineers with complex tasks. You can talk to it to automate processes and make your work in Autodesk® Civil 3D® easier and faster.

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

Automates solids Extraction from Autodesk® Civil 3D® surfaces and corridors. Customizable depth, layer, and color options available. Simplify your workflow and improve your design process

Automate road design tasks in Autodesk® Civil 3D®, saving time and improving accuracy. Create surface profiles, layout profiles, profile views, corridors, corridors surfaces and sample lines.

Create surfaces and point groups from AutoCAD® points, blocks, elevation texts, contours, and more. Import/export SDR/GSI/TXT/CSV/Excel/PNT. Automate style and volume calculations and alignments.

Automesher LT is an add-on for Autodesk® AutoCAD® that expands its functionality by enabling the import and export of popular 3D mesh file formats. In addition, it allows the conversion of 3D meshes.
