Attributes Panel

The Attributes Panel displays information and editable attributes for the currently selected items. If multiple different types of items are selected, each type of item is grouped separately in the Attributes Panel. If multiple items of the same type are selected, the Attributes Panel indicates the number of selected items and whether their properties have matching values.

Common Widget Types

The Attributes Panel includes common types of widgets, such as those described in this section.

Spin Boxes

Typically, spin boxes are used to modify integer or floating-point values. You can modify spin box values in one of these ways:

  • Click and drag the attribute name ("Speed Limit" in the previous figure).

  • Click the up or down arrow buttons on the right side of the spin box value.

  • Click the value ("40 mph" in the previous figure) and type or paste a value directly.

Radio Buttons

Radio buttons are used to select between a specified list of enumerated values.

Combo Boxes

Combo Boxes are another way to select between a specified list of enumerated values. Typically, combo boxes are used for infrequently used attributes and attributes with a large number of potential values.


Toggles are used to toggle Boolean (on or off) attributes.


Buttons are used to run operations on the selected objects. Some buttons are displayed in the Attributes Panel, while others are displayed on the Sub-Tool Bar.

Color Pickers

Color pickers are used to select a color. To use a color picker, click the displayed color to open a color selection dialog box.

In this dialog box, you can:

  • Select a color from a predefined set of basic colors ("Basic colors" at the top-left)

  • Free-form select a color (color palette at the top-middle)

  • Change the color intensity (intensity slider at the top-right)

  • Select a color displayed anywhere on your screen ("Pick Screen Color" button)

  • Select from your own set of custom colors ("Custom colors" at the bottom-left)

  • Add a color to your own set of custom colors ("Add to Custom Colors" button replaces the last-selected custom color with the current displayed color)

  • Explicitly specify a color using Hue/Saturation/Value channels

  • Explicitly specify a color using Red/Green/Blue channels

  • Explicitly specify an HTML hex color (of the form #RRGGBB)

  • Change the transparency of a color ("Alpha channel")

Asset Pickers

Asset pickers are used to reference an asset from the Library Browser.

To assign an asset to an asset picker, follow these steps:

  1. Locate the desired asset in the Library Browser.

  2. Click and drag the asset into the asset picker.


Most asset pickers accept only certain types of assets. For example, you can assign Prop Model Assets and Extrusion Assets (among others) to a Prop Curve, but you cannot assign a Material Assets.

Some asset pickers enable you to have no asset assigned. To remove an asset from an asset picker, right-click the asset picker and select Clear. Alternatively, click the asset picker and press Delete.

To quickly locate the currently displayed asset in the Library Browser, click the asset picker. The asset is selected in the Library Browser.

Although the asset is selected, its attributes do not display. To see and modify the asset attributes, click the selected asset in the Library Browser.

View and Edit Attributes of a Single Object

  1. Select the object in one of the main panels (such as the 3D Edit Window, 2D Edit Window, or Library Browser).

  2. View or modify the attributes displayed in the Attributes Panel.

View and Edit Attributes of Multiple Objects

If you select multiple objects in one of the main panels (such as the 3D Edit Window, 2D Edit Window, or Library Browser), the Attributes Panel provides additional features for interacting with multiple objects.

This image shows the Attributes Panel after selecting two Prop Points. For this figure, note these important aspects:

  • The group label ("Prop Instance (2)") shows the number of selected objects (2 in this case).

  • The Prop Style asset picker is grayed and dimmed, which indicates that the two props have different assets assigned.

    • The asset picker shows the style of the first selected object.

    • If the asset picker value is changed, it will modify all selected objects (and the asset picker will no longer be grayed/dimmed).

  • The selected objects have different Position.X and Position.Y values, but their height (Position.Z) value is the same. Modifying the Position.X or Position.Y values applies the same value to all selected objects.

  • Clicking a button (such as the Add Sign button in the figure) applies the operation to all selected objects.
