Special Instructions for Updating

How do I register AHGW?

See the detailed instructions at AHGW:Registering AHGW.

Which version of AHGW do I need?

Each AHGW Toolbox is created for a specific version of ArcGIS. If you try to use a version of the AHGW Toolbox not designed for the version of ArcGIS you're using, it will not work. The best course is to determine which version of ArcGIS you have, then download the appropriate version of the AHGW Toolbox.

You can see the current list of available versions on our AHGW Downloads page.


How do I convert existing 2D cross sections to 3D with Subsurface Analyst?

See the instructions at AHGW:Converting 2D Cross Sections to 3D Using Subsurface Analyst.

What if I run the Create BoreLines tool to create 3D bore lines but no bore lines are created?

You may need to create a new feature dataset with Z values below zero by using the Create Feature Dataset tool in ArcGIS. A basic workflow can be found at AHGW:Troubleshooting 3D Bore Lines.
