Modify panel > Configure Modifier Sets button > Configure Modifier Sets
This dialog lets you create custom modifier and button sets for the Modify panel.
To customize the current modifier and button set:
Use Total Buttons to choose the number of buttons in the set.
Assign buttons by dragging the names of modifiers in the dialog's Modifiers list to buttons in the Modifiers group box.
Autodesk VIZ updates the Modifiers list. You can customize the set without saving it, but if you save a new set under a new name, you can use it later.

Modifiers—Lists all modifiers currently available. It's organized into these categories: VIZ STANDARD, VIZ SURFACE, SURFACE TOOLS, VIZ EDIT, RADIOSITY, LIGHT, VIZ ADDITIONAL, SPLINE EDITS and WORLD-SPACE MODIFIERS. To add a modifier to the current button set, drag the modifier's name from this list onto a button in the Modifiers group box.
Sets—This edit field and drop-down list lets you choose the modifier set to edit. To create a new button set, enter the name in the edit field, and then click Save.
Save—Saves the current button set.
Delete—Deletes the current button set.
Important: You can't undo deleting a button set.
Total Buttons—Sets the number of buttons in the button set. A button set can have up to 32 buttons.
Previews how the button set will appear on the Modify panel. Because the box shows only 16 buttons at a time, a scroll bar on the right lets you see any remaining buttons.
To change a button, drag the name of a modifier from the Modifiers list to a button in this group box, or click the button (its border highlights) and then double-click the modifier name.
