Using the VieW tools 153

Walkthrough: The Walkthrough helps you create an animation that records a movie as if you
were walking through a part or assembly.
Change Display States: Display states help you retain visual or display settings for a docu-
ment, and this tool enables you to switch between stored states.
Hide All Types: Any of the icons with a picture of an eye on them can be used to show or hide
the entity depicted in the icon. This includes planes, axes, sketches, curves, relations, parting
lines, decals, and so on. You can access these icons quickly from the Heads-Up View toolbar.
The eye icon on its own is Hide All Types, and it toggles each of these individual settings.

Zebra Stripes and Curvature
Zebra Stripes, another geometrical analysis tool that helps you visualize the quality of transitions
between faces across edges, simulates putting a perfectly reflective part in a spherical room
where the walls are painted with black-and-white stripes. In high-end shape design, surface
quality is measured qualitatively using light reflections from the surface. Reflecting stripes make
it easier to visualize when a transition between faces across an edge is not smooth. Zebra Stripes
can help you identify these three cases (see Figure 5.9):
Contact: Faces intersect at an edge but are not tangent across the edge, such as at the edges of
a cube. This condition exists when stripes do not line up across the edge.
Tangency: Faces are tangent across an edge but have different radii of curvature on either side
of the edge (noncurvature continuous), such as between a fillet face and an adjacent face. This
condition exists when stripes line up across an edge, but the stripe is not tangent to itself
across the edge.
Curvature continuity: Faces on either side of an edge are tangent and match in radius of
curvature. Zebra Stripes are smooth and tangent across the edge.
