You can have as many 3D Views as needed in order to examine your models from various angles. Specific uses of the 3D View windows include:

Visualization of objects associated with models, for example, forces and moments applied to a model
Visualization of motions that are pre-recorded or which result from an analysis
A visual check of the validity of the model, for example, the correctness of muscle wrapping which requires visual inspection in different configurations

Creating 3D Views

You do not have to explicitly create 3D Views. A new 3D View window opens automatically when the first model is loaded into OpenSim. Subsequent models are displayed in the same 3D View window. An offset is computed by OpenSim based on the dimensions of the loaded models to place the new model in the 3D View so that it does not overlap with previously loaded models. You can control this offset using the Display → Model Offset… option, accessed from the node in the Navigator window that represents the model visit Object-Specific Commands for more information.

To explicitly open a new 3D View window (without loading a model):

	Click the Window menu from the main OpenSim menu bar and select the Add View option.

If you have a 3D View window already open, you can also create a new 3D View window:

	Go to the existing 3D View window. Right mouse click the tab label and select the Add.

If another 3D View window is already open, the newly created window will be a tabbed window overlaid on the previously open 3D View window. You can drag these windows apart as needed. If the new window was created from an existing 3D View window, the camera in the new window will be in the same position as in the original window. OpenSim will not create a new 3D View if you close the 3D View window that was automatically created when the first model was loaded.

The figure below shows a 3D view window with loaded model:

The two tabs in the upper-left indicate that there are two 3D View windows, one of which was created from the other.

Opening Multiple 3D Views

You can open many 3D View windows simultaneously to obtain multiple views. Multiple views can come in handy if a user wants to see a model from multiple angles at the same time. This can be useful, for example, when running a gait simulation or when moving a muscle attachment point in order to place it accurately on a bony landmark.

Closing 3D Views

	3D View windows can be closed by clicking the “x” next to the tab label on the 3D View window.

Naming 3D Views

OpenSim creates 3D View windows with default names that start with the prefix "view" followed by a number (e.g., view0, view1).

You can change the names to more meaningful names:

Right mouse click on the tab label of the 3D View window and selecting "Rename…".
This brings up the dialog box, populated with the current 3D View name (see figure below)

3. Enter the new name in this dialog box then click OK.

Duplicate names are not allowed.
