You can create surfaces with many of these operations to define shapes or
aspects of the part body. For example, you can use a curved surface as a
termination plane for cuts in a housing.
You can edit the characteristics of a feature by returning to its underlying
sketch or changing the values used in feature creation. For example, you can
change the length of an extruded feature by entering a new value for the
extent of the extrusion. You can also use equations to derive one dimension
from another.

Sketched Features
Most parts start with a sketch. A sketch is the profile of a feature and any
geometry (such as a sweep path or axis of rotation) required to create the
feature. Your first sketch for a part can be a simple shape.
Sketched part features depend on sketch geometry. The first feature of a part,
the base feature, is typically a sketched feature. All sketch geometry is created
and edited in the sketch environment, using Sketch commands on the ribbon.
You can control the sketch grid, and use sketch commands to draw lines,
splines, circles, ellipses, arcs, rectangles, polygons, or points.
You can select a face on an existing part, and sketch on it. The sketch displays
with the Cartesian grid defined. If you want to construct a feature on a curved
surface, or at an angle to a surface, first construct a work plane. Then sketch
on the work plane.
The browser displays the part icon, with its features nested under it. Surface
features and work features are nested or consumed by default. To control
nesting, or consumption of surface and work features for all features, set the
option on the Part tab of the Applications Options dialog box. To override
consumption on a per-feature basis, right-click the feature in the browser, and
then select Consume Inputs.
