Environment Files & E3D Editors 505
The E3D Editor
By default, environment files are saved at the same location as the model they are associated with. Whenever the E3D window is opened, the environment file for the associated model will be used to populate the E3D window.
☞ The default environment file, Extend3D.mis, can be accessed by every model. Only custom environment files need to be saved in the same location as the model they are associated with.
The E3D Editor
The E3D Editor is an interface to the E3D window that provides extensive and sophisticated control over the contents and appearance of the window. It allows you to alter aspects of the E3D animation area without affecting the appearance or structure of the 2D model. It provides greater flexibility than using blocks from ExtendSim libraries and it allows you to perform tasks you can’t do using library blocks, such as:
• Defining custom pathways that are not linked to the position of the 2D model’s blocks.
• Placing 3D objects directly in the E3D window, without having to add them as blocks in the 2D model.
• Creatingspecializedterrains,suchasaddingcontourstothefloor,removingitsgrid,orusing a different floor pattern
• To give a very advanced animator complete control over the E3D environment.
Learning about the E3D Editor
So that you can more clearly see how the E3D Editor works:
Place an Activity block (Item library) anywhere on a new model worksheet, as shown on the right.
Save the model as “EditorExploring”. Accessing the Editor
With the EditorExploring model the active window, open the E3D window.
The appearance of this window is defined by the default environment file “Extend3D.mis”.
Activate the E3D Editor using one of the following methods:
Click the F11 key on your keyboard.
Or, click the ExtendSim application icon at the left side of the E3D window (Windows only). This causes a menu to appear so you can select the Editor.
☞ If the Editor does not open correctly on a Macintosh, be sure there is no
default keyboard shortcut for F11 in the System Preferences > Dashboard & Expose dialog.
Exiting and closing
To exit the E3D Editor, use the close box at the top of the window. This also closes the E3D window. To toggle between the E3D Editor and the E3D window without closing either of them, use the Toggle E3D Editor command or the F11 key.
