HoleBASE SI Extension for AutoCAD Civil 3D

Geotechnical Data in the BIM Process and CAD Drawings

Visualizing and sharing your data in a 3D BIM environment greatly enhances your understanding of your site and increases the quality of your engineering output.

Production of drawings and models are much faster with the dynamic connection and updating of HoleBASE SI and AutoCAD Civil 3D using the HoleBASE SI Extension for AutoCAD Civil 3D.

The connection even allows you to automate the updating of your drawings and models as you get new data, allowing you to see updates to your model as they are entered into HoleBASE SI.

  • The speed at which we can now create ground models through the varying layers of stratigraphy will prove to be of huge time saving benefit. Not only does this help greatly when producing geotechnical profiles but will also be very useful for calculating earthwork volumes.

  • Friendly support & always willing to help. I also like the fact that Keynetix move with the times, are constantly looking to improve on products and the way they teach others – the videos being VERY useful; there should be more.
