Crouching
NOTE This function only works in connection with collision.
When walking or flying around the model with collision activated, you may
encounter object that are too low to walk under, a low pipe for example. This
function enables you to crouch under any such objects.
With crouching activated, you will automatically crouch under any objects
that you cannot walk under at your specified height, thereby not impeding
your navigation around the model.
TIP To temporarily crouch under a low object, hold down the Space bar to allow
navigation to proceed.
To toggle crouching
1 When using the Walk or Fly tool, click Viewpoint tab ➤ Navigate
panel ➤ Realism drop-down
➤ Crouch check box.

Collision
This function defines you as a collision volume - a 3D object that can navigate
around and interact with the model, obeying certain physical rules that confine
you within the model itself. In other words, you have a mass and as such,
cannot pass through other objects, points or lines in the scene.
You can walk over, or climb over objects in the scene that are up to half the
height of the collision volume, thus allowing you to walk up stairs, for
example.
The collision volume, in its basic form, is a sphere (with radius = r), that can
be extruded to give it height (with height = h >= 2r). See diagram below:
