Part 3. Working with Freedom

Freedom enables you to explore project models without specialist design software or specialist skills. In this section, you will learn how to:
• Manage files
• Use Freedom tools
• Use TimeLiner playback tools

Chapter 4. Overview

The basis of Autodesk NavisWorks Freedom 2009 is its ability to walk through any size model in real time. NavisWorks guarantees a user-defined frame rate using a unique algorithm which automatically calculates which items to render first during navigation, based on the size of items and distance from the viewpoint. Items which NavisWorks does not have time to render are, therefore, sacrificed or "dropped out" in the name of interactivity. These items are, of course, rendered when navigation ceases. The amount of drop-out depends on several factors including: hardware (in particular graphics card and driver performance), as well as the size of the NavisWorks navigation window and the size of the model. If you wish to reduce drop-out during navigation, you have the option to reduce frame rate and, therefore, trade it off against drop-out.
When working with truely large "supermodels" in NavisWorks, you will require a sufficient amount of RAM to load and review the data. NavisWorks employs JetStream technology which optimizes the usage of the available RAM. Before running out of memory, NavisWorks will page unnecesary data to the hard disk, freeing up space for loading to continue. JetStream technology also enables the user to commence navigating the supermodel, before it has completely loaded into memory.
NavisWorks is large address aware, utilizing any additional memory assignment following the 3GB switch available on Windows XP systems.
To start NavisWorks, double-click the NavisWorks icon on the desktop, or go to Start > Programs > Autodesk > Autodesk NavisWorks Freedom 2009 > Autodesk NavisWorks Freedom 2009. The following sections will describe the interface in more detail.
NavisWorks contains full context-sensitive Help. Click , and click the toolbar button or menu option to display the appropriate Help topic. Or, alternatively, go to the Help menu.
14

Chapter 5. File Management

To manage files, you can use both the File menu and the Standard toolbar.

File Menu

The File menu includes the following items:
• New
• Open
• Open URL
• Print
• Print Preview
• Print Setup
• Recent Files
• Exit

New Files

This option resets NavisWorks and closes existing files. To create a new file:
• On the File menu, click New

Opening Files via URL

With Autodesk NavisWorks Freedom 2009 you can open NavisWorks published .nwd files via the Internet. Having uploaded your .nwd file to a web server, this file can then be opened directly from within NavisWorks. Utilizing JetStream technology, it will not be necessary for the entire file to be downloaded before navigation can commence - between 10% and 50% will be sufficient for this, depending on the file structure. (The greater the hierarchical structure of the model, the closer to 50% will be required for navigation to commence. Similarly, the lesser the hierarchical structure of the model, the closer to 10% will be required).
File Management
To open a file via a URL:
• On the File menu, click Open URL.

Printing

You can print a hard copy of the current viewpoint to any printer or plotter.
Printing the Current Viewpoint

NWD Files
.nwd files are files published by NavisWorks Publisher and are snapshots of the model at a certain time.
DWF Files
Autodesk's DWF (Design Web Format) was specifically developed by Autodesk as a file format for architects, engineers, and GIS professionals to share design data. The NavisWorks file reader reads all 3D geometry, as well as textures and properties. A full list is given below.
Supported Entities
• All 3D geometry
• Texture coordinates
• Colors (per-vertex, per-face)
• Property fields
• Categories
Unsupported Entities
• 2D lines/plot sections
• Thumbnails
• Marked-up sketches

Factor for more information.
4. Enter the Max Facet Deviation. This will facet entities to within the specified tolerance. See Max
Facet Deviation for more information.
5. Click OK to set these options or Cancel to exit the dialog without setting them.
19

Chapter 7. Navigating

NavisWorks enables intuitive and interactive navigation around your 3D models at a guaranteed frame rate. The nine navigation modes give you complete flexibility to navigate around the model in real time. In addition to these navigation modes, there are selection and measuring tools that further facilitate the interrogation of model data.
The navigation tools allow you to do things such as focus on objects and change the view parameters. There are also options to look from predefined views, set the world up vector to a direction different than the one brought through from the CAD model.

Navigation Modes

There are nine navigation modes to control how you move around the main navigation view - six camera-centric modes and three model-centric modes. In a camera-centric mode, the camera moves within the scene, whereas in a model-centric mode, model moves inside the scene. For example, the Orbit and Examine modes essentially do the same thing, except that Orbit moves the camera around the focal point and Examine moves the model around the focal point. Movement in each mode is based on the cursor keys, the Shift and Control keys and mouse drags. The mouse wheel is also supported, allowing quick and easy zooming or tilting, depending on the current navigation mode.
Note:
Dragging with the left mouse button while holding down the Control key performs the same actions as dragging with the middle mouse button, which is useful if you only have a two-button mouse.
The Shift and Control keys modify the movement, for example holding down Shift in Walk mode speeds up movement, and holding down Control in this mode, glides the camera left/right and up/down.
Note:
Gliding the camera is opposite to panning the model. Gliding is a camera-centric motion and panning is a model-centric motion.
Below is shown the Navigation Mode toolbar and the navigation modes available:

Walk mode enables you to walk through the model on a horizontal plane ensuring that "up" is always "up".
To walk through a model:
Navigating

Dragging the left mouse button, or using the cursor keys, spins the camera left and right and moves it forwards and backwards.
Holding down the Shift key speeds up this movement. Holding down the Control key glides the camera left and right and up and down. As walk mode is
camera-centric, this mode differs from the normal pan mode in that the camera is moved rather than the model.
Spinning the mouse wheel tilts the camera up and down.
