The purpose of this inspector is to retain the user interface small and very organized: Similar to SketchUp's inspector dialogs, it facilitates the users to choose one or more entities and displays their attributes. By editing the text fields, modifications can be done instantly to the entities.
Application: (Menu) Window → Attribute Inspector
The dialog demonstrates the attribute dictionaries of the drawing elements which are chosen currently. Another component can be chosen with the help of SketchUp's selection tool.
Press the +, ‒ buttons on the left side to include or eliminate a attribute dictionary, and press +, ‒ on the right side to include or eliminate an attribute.
To choose other types of entities, select the type from the dropdown and perform the following activities:
Drawing elements: Apply SketchUp's selection tool to choose one or more drawing elements in the model (edges, faces, groups.)
Definitions: Apply SketchUp's selection tool to select components/groups/images
Materials: By applying the materials browser and select a material. Attribute Editor will demonstrate the present material (could be not compatible with OS X because of API bug).
Layers: Apply the layer manager and verify the radio button of the layer.
Scenes: use the scenes manager and double-click the scene (to make it the current scene).
This sketchup plug can be accessed from the extension warehouse.
