Reference for the Navigator Toolbar

Buttons

The Navigator toolbar contains the following buttons.

Button	Description
	Synchronizes the model in the Navigator window with the AutoCAD model. The Navigator window is not updated automatically. Click this button every time you want to navigate around the latest model.
	Changes the current AutoCAD view to the view in the Navigator window.
	Changes the view in the Navigator window to the current AutoCAD view.
	Selects walk mode and enables you to walk through the model on a horizontal plane.
	Selects look around mode and enables you to look around the model from the current camera position.
	Selects zoom mode. Dragging the left mouse button up and down or using the UP and DOWN ARROW keys zooms in and out respectively.
	Selects zoom-to-a-box mode. Dragging a box with the left mouse button over the model fills the view with the contents of the box. Holding down the SHIFT or CTRL keys or spinning the mouse wheel, temporarily switches this mode to zoom mode.
	Selects pan mode. Dragging the left mouse pans the model up, down, left and right. Holding down the SHIFT or CTRL keys or spinning the mouse wheel, temporarily switches this mode to zoom mode.
	Selects orbit mode. Dragging the left mouse button or using the UP, DOWN, LEFT ARROW, and RIGHT ARROW keys rotates the camera around the model. Holding down the SHIFT key or spinning the mouse wheel, temporarily switches this mode to zoom mode. Holding down the CTRL key temporarily pans the camera.

Holding down the SHIFT key or spinning the mouse wheel, temporarily switches this mode to zoom mode. Holding down the CTRL key temporarily switches this mode to pan mode.
	Selects fly mode. Holding down the left mouse button moves the camera forward. As in a flight simulator, the left mouse button banks left/right when dragged left or right and tilts up/down when dragged up or down. The UP and DOWN cursor keys zoom in and out respectively, and the LEFT ARROW and RIGHT ARROW keys spin the camera left and right respectively. Holding down the SHIFT key speeds up this movement. Holding down the CTRL key rotates the camera around its viewing axis, while still moving forward.
	Selects turntable mode. Dragging the left mouse button left and right, or using the LEFT ARROW and RIGHT ARROW keys spins the turntable left and right respectively. Holding down the SHIFT key or spinning the mouse wheel, temporarily switches this mode to zoom mode. Holding down the CTRL key temporarily switches this mode to pan mode.

The Context Menu

Right-clicking in the Navigator window opens a context menu.

Focus on Item

Focuses the camera on the selected item. The point you click becomes the focal point for examine, orbit, and turntable navigation modes.

Speed

Frame Rate

Specifies the number of frames per second (FPS) that are rendered in the Navigator window.

The default setting is 6. You can set the frame rate from 1 through 20 frames per second. Reducing the value reduces drop-out, but can cause jerky movement during navigation. Increasing the value ensures a smoother navigation, but increases drop-out.

Hardware Acceleration

If your video card meets the Autodesk Navisworks minimum system requirements, you can improve the graphical performance by turning on hardware acceleration.

Note: If your video card does not support hardware acceleration, this option is not available.

Viewpoint

Rendering

Selects rendering mode for your model. Choose from:

• Shaded - renders the model with smooth shading and without textures. This is the default option.
• Wireframe - renders the model in wireframe; all triangle edges are visible in this mode.
• Hidden Line - renders the model in hidden line; this is equivalent to rendering model as shaded and wireframe at the same time. The output is low quality as all the facet edges in the model are visible.

Lighting

Selects lighting mode for your model. Choose from:

• No Lights - turns off lighting. The model is shaded with flat rendering.
• Head Light - uses a single directional light located at the camera that always points in the same direction as the camera. This is the default option.
• Scene Lights - uses any lights defined in the model, or two default opposing lights, if none are available.

Navigation Mode

Selects navigation mode. The options available here are the same as on the Navigator toolbar, with one exception. The Select option enables you to select items in your model. You can select multiple items by holding down the CTRL key while selecting items.

Navigation Tools

Select View All to display the entire model.

Perspective Camera

Selects perspective camera view.

Orthographic Camera

Selects orthographic camera view.

Options

Culling Options

Opens the Culling Options Dialog box.

Close Files on Open

Indicates whether NWC file created for the model is closed once it has been loaded into memory.

Selecting this option unlocks NWC files for editing by other users.

Max Image Texture Size

Specifies the maximum size for texture images in pixels.

The higher the value, the higher the load on your graphics card, as more MB in memory is required to render textures.
