The arrows on the cutting plane line point away from the sectioned view.
A half section view is used when a view is needed showing both the exterior and the interior of a
symmetrical object.

Introduction to Modeling
Typically, part geometry is stored three ways:
wireframe
surfaces
solids
Wireframe models store the equations of the boundary curves of the part. With wireframe, it's impossible to check
for three-dimensional interfer

Variational Geometry
The downstream flexibility of parts created from extruded or revolved sections comes from the concept
of variational geometry, which includes constraints. Constraints look like dimensions when they're first
applied, but they

Chapter 5 introduces the theory, techniques, and standards of multiviews, which are a standard method for
representing engineering designs. The chapter describes how to create one-, two-, and three-view sketches

Introduction
Sketching is an important method of quickly communicating design ideas; therefore, learning to
sketch is necessary for any person working in a technical field. Sketching is as much a way of
thinking as it is a method of recording ide
The Sketch Pad Concept - How
Wireframe Geometry Is Stored
At a simple level, wireframe geometry is either sketched on the workplane to create
sections to extrude, revolve, or loft into parts; or it's sketched in place on a face or

In contour dimensioning, dimensions are placed in the most descriptive view showing the
contour of features.
Datum dimensioning has all of the dimensions calculated from a common origin point.
