Five Problems : All problems will be (somewhat) equally important, equally long
Chapter 3 : Engineering Geometry
Engineering geometry is the geometric elements in engineering design, they are
the building blocks of engineering design
The shape description of an object relates to position of its component geometric
in elements in spa
Chapter 5 : Multiview and Visualization
Projection Theory : based on graphically represent 3d objects and structures on
2d media. Projection theory is based upon 2 variables, line of sight(the imaginary
ray of light connecting eye and object) and plane o
Chapter 1 : Introduction To Graphic Communication
Engineering design process starts with visualization, then see the problem and
then find solutions. Later sketches are made from which geometric models are
created and finally 3d models are made
92% of d
Chapter 2 : Sketching
Technical drawing has 3 methods : freehand sketching, mechanical sketching
and digital
Technical sketching is mostly a freehand sketching that may not represent the
object in great detail but it is to capture a particular idea befo
Chapter 6 : Auxiliary views
An auxiliary view is an orthographic view that projected into a plane which is not
one of the 6 principal views
There are two ways of creating auxiliary views :
Fold-Line method : the object is thought be suspended in a glass
Chapter 4 : Modeling Fundamentals
A solid model has information of what is there inside of the model as well as
about the surface. Modelers define what is called manifold model where manifold
boundary separates a spatial region into what is inside and ou
Chapter 8 : Section views
Sectional views are views to improve clarity of design. They are done in the ideation
stage to improve communication. Sectional drawings are multiview drawings that contain
reveal interior features.
Primary reason to create sec
Chapter 9 : Dimensioning and Tolerancing
Geometrics is the science of specifying and tolerancing the shapes and locations of
features. The size information is given by dimensions.
A fully defined part has 3 elements : dimensions, graphics and notes.
There
Chapter 7 : Pictorial Projections
Axonometric projection is a parallel projection pictorial drawing of an objected created by
rotating the object about an axis relative to a projection or pictorial plane
The four principal projection techniques are : mu

Findings from Reverse Engineering
Within the coffee maker, there are a few main elements that are especially important to
the design of the product. One of these is the water reservoir. [picture] This space in the back of

Engineering Analysis of the Device
Coffee is a big part of many peoples lives. Mr. Coffee is a brand that helps make
peoples life easier. In this project we were required to take apart and measure the parts of the
DR4 model of the Mr. Coffees coffee maker
