Add-Ins are one of the exciting new features in GeoStudio 2007. They allow GeoStudio to be extended in nearly infinite ways, by adding custom-made functions and SIGMA/W constitutive models.

While some Add-Ins can be downloaded from our website and installed directly on your computer (expect this list to grow!), the most powerful aspect of Add-Ins is that you can write your own. In fact if you have GeoStudio 2007 installed, you already have everything you need on your computer to write your own Add-In today.

The Add-In Developer's Kit (also called the SDK, or Software Development Kit) contains instructions, templates, scripts, and sample code to get you started. Download it here or from the GeoStudio 2007 Downloads page:

You may find it easier to write Add-Ins using Microsoft Visual Studio Express Editions. These free tools are designed for novice programmers, and give you your choice of programming language, from Visual Basic, C# or C++.
