Explore Your Model
Autodesk Navisworks Freedom 2011 enables you to walk through a scene in real
time.
Navigate a Scene
In Autodesk Navisworks, you have a variety of options for navigating
your scene.
You can directly manipulate your position in 3D space with
navigation tools on the navigation bar. You can also use
StreeringWheels
®
that travel with the cursor, and can save you time
by combining many of the common navigation tools into a single
interface.
You can use the ViewCube
®
, a 3D navigational tool that enables
you to reorient the view of a model by clicking predefined areas on
the cube. For example, clicking the front of the ViewCube turns the
view until the camera is facing the front of the scene. You can also
click the ViewCube and drag it to rotate the view freely.
You can use the tools on the Viewpoint tab ➤ Motion Settings
panel to control the speed and realism of your navigation. So, for
example, you can walk down stairs or follow terrain, crouch under
objects, use an avatar to represent yourself within the 3D model.
Animating Navigation
As you navigate in Autodesk Navisworks, you can record viewpoint
animations, and then play them back. For more information, see
“
Play Back Animations” on page 151.
Orientation in 3D Space
Although Autodesk Navisworks uses the X, Y, Z coordinate system,
there is no hard-and-fast rule as to which way each of these particular
axes actually “points”.
Autodesk Navisworks reads the data necessary to map which way
is “up” and which way is “north” directly from the files loaded into
your scene. If this is not possible, by default, Z is treated as “up”
and Y is treated as “north”.
It is possible to change the “up” and “north” directions for the entire
model (world orientation), and the “up” direction for the current
viewpoint (viewpoint up vector).
