Back up first. This guide edits Rhino configuration files. Keep a copy of your settings folder so you can restore it if needed.

Step 1

Back up your default theme folder

Press Win + R, enter %AppData%\McNeel\Rhinoceros\8.0\settings, and copy the settings folder to a safe location.

Step 2

Install an XML editor

Install Microsoft XML Notepad, or use another XML editor you trust.

Step 3

Open Rhino’s default XML file

Inside the settings folder, open Scheme__Default\Rhino.UI.Resources.rui.default_<guid>.xml. The exact GUID portion varies.

Step 4

Confirm the tree structure

If the icons have not been modified, the file should show a tree similar to the example below.

Open the RhinoUI XML file

Download your purchased files from Gumroad, then open the supplied icon XML file in a second editor window.
