This article contains a sample script for creating an ExtractPoints module and modifying its properties. The ExtractPoints module will accept both lattices and well data as input, but only the lattice input is shown here. For well-based input, please refer to the How can I import well data into Voxler via automation? knowledge base article.

To run this script:

1. Copy the script below, or click here to download the BAS file: ExtractPointsModule.bas.
2. In a Windows Explorer window, navigate to C:\Program Files\Golden Software\Voxler 4\Scripter.
3. Double click on Scripter.exe to launch Scripter.
4. Press Ctrl+A to select all of the existing lines then press Delete.
5. If you copied this script, press Ctrl+V to paste it into Scripter. If you downloaded it, click File | Open, select the BAS file from your downloads directory, and click Open.
6. Click Script | Run to run the script.
