Utilities panel > Utilities rollout > Configure Button Sets button
This dialog lets you create custom button sets for the Utilities panel. Once created, these utility sets are available from the Sets button on the Utilities panel.
To customize the current button set:
Use Total Buttons to choose the number of buttons in the set.
Assign buttons by dragging the names of utilities in the Utilities list to buttons in the Utilities group box.
Clear buttons by dragging them to the Utilities list on the left.
Autodesk VIZ updates the Utilities rollout. You can customize the button set without saving it, but if you save a new button set under a new name, you will be able to use it later.
Tip: Don't alter the Default button set. Create a new one instead.

Utilities List—This lists all the utilities currently available to Autodesk VIZ. It is organized into eight categories: VIZ STANDARD, Utilities,, NURBS, Radiosity, Strokes, MAXScript Tools, Internet Extensions, and Realviz Products. To add a utility to the current button set, drag the utility's name from this list to the Utilities group box.
Sets edit field and drop-down list—Lets you choose the button set to modify. By default, there is a single button set called VIZ Default.
Tip: Don't alter the Default button set. Create new sets as the need arises.
Save—Saves the current button set.
Delete—Deletes the current button set.
Warning: You can't undo the deletion of a button set.
Total Buttons—Sets the number of buttons in the button set. A button set can have up to 32 buttons.
