Last Update: 4/2018

The Open Standards for AutoCAD Civil 3D are a "variant" of the National CAD Standards (NCS).
These Open Standards have been civilized for civil engineering, survey, and government agency production and publication use.

National CAD Standards Compliance

These Standards purposefully do not conflict with the AIA NCS and UDS recommendations for versions 4.0, 5.0 and 6.0.
We recommend you purchase a copy of the National CAD Standards and support that ongoing effort.

Standards History

The Standards have been in continuous development in one form or another since the earliest release of the initial beta of AutoCAD Civil 3D.
They have been publically updated since the release of AutoCAD Civil 3D 2009.
Autodesk officially sponsered a 2010 release and included it with the product release.
This Autodesk product was publically called the US California Country Kit

This product was and remains a generic US Imperial standard with intentionally little or no regional bias.

The Standards and Conversion

The Framework for Civil 3D as a product has been successfully ported to Metric all or in part.
The Framework Standards are in the use in multiple countries.
The estimated organization base count probably exceeds 6000+ organizations.

Our Framework production solution products are available for purchase here in various levels of detail and complexity include tools to manage, maintain, and customize these standards and more.
