If your Surfer project was created with all different fonts and font sizes, or it was created with different fonts/sizes than what you need, you can use a script to change them all. This script loops through all objects in your project and changes the font size and font face for all labels, titles, and/or text associated with those objects.

Note: This does not apply to Grid Values map labels, nor does it apply to vector Base map labels, since those two maps do not currently have automation commands for editing label font properties.

To run this script:

1. Copy the script below, or download the attached BAS file: ChangeFontPropertiesForEntireProject.bas.
2. Download the attached Plot1.srf file.
3. In a Windows Explorer window, navigate to C:\Program Files\Golden Software\Surfer.
4. Double click on Scripter.exe to launch Scripter.
5. Press Ctrl+A to select all of the existing lines then press Delete.
6. 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.
7. Change the file path, font face, and font size in the User-defined variables section (the file path should be the location you downloaded Plot1.srf to, such as your Downloads directory).
8. Click Script | Run to run the script.
