In-Depth Information
Zebra Analysis displays stripes that allow you to better visualize how the curvature of sur-
faces blend. The smoother the stripes, the better the transition between surfaces.
Curvature Analysis displays colors to indicate the direction and amount of curvature in a
surface. A negative curvature is a saddle shape and displays a blue color. A positive curvature,
or bowl shape, displays in red.
Draft Analysis displays colors to help you determine draft angles. Draft angles are often used
in the design of objects that are to be cast from a mold and are important in allowing the cast
object to be easily removed from the mold.
The Analysis Options tool opens the Analysis Options dialog box, which enables you to
control the way the different analysis tools are displayed. You must use a visual style other than
Wireframe.
The Bottom Line
Create a simple 3D mesh.
Mesh modeling allows you to create more organic 3D forms by
giving you unique smoothing and editing tools. You can start your mesh model by creating a
basic shape using the mesh primitives.
Master It
Name at least six mesh primitives available on the Primitives submenu under
Draw
3D Modeling
Meshes on the menu bar.
Edit faces and edges.
The ability to edit faces and edges is essential to creating complex
shapes with mesh objects.
Master It
Name the tool that is used to divide a face into multiple faces.
Create mesh surfaces.
The Mesh primitives let you create shapes that enclose a volume.
If you just want to model a smooth, curved surface in 3D, you might fi nd the surface mesh
tools helpful.

How many objects are needed to use the Edge Surface tool?
