Inflection Point
An inflection point of a curve or surface is a point at which the
curvature changes from concave to convex, or conversely. An
inflection point is shown in Figure 1–5.

Geometrical Set
As you build your surface model, the display of wireframe,
surface, and even solid geometry can make the model difficult to
visualize. Geometrical sets are used to group geometry by
function or type, and to organize the model.
You can have as many geometrical sets as required to suit your
design intent. Geometrical sets do not affect the mass properties
of the model. To add a new geometrical set, select
(Geometrical Set...) from the Tools section of the Action Bar.
Alternatively, if you select on the 3D Shape in the tree you can
select (Geometrical Set...) from the context menu.
A new geometrical set added to the model becomes the current
set, as shown in Figure 1–6.

To set a geometrical set as the active set, right-click on the set in
the specification tree and select Define In Work Object.
