Standards
Standards for Technological Literacy

Standard 11:Students will develop abilities to apply the design process.

BM E:The process of designing involves presenting some possible
solutions in visual form and then selecting the best solution from many.
BM J:Make two-dimensional and three-dimensional representations of
the designed solution.

Standard 12:Students will develop the abilities
to use and maintain technological products and
systems.

BM J:Use computers and calculators in various
applications.
Purpose

 Identify basic geometric
relationships of shapes and solids.
 Use coordinate system to express geometric
relationships.
 Create a three-dimensional (3D) model of an object.
 Demonstrate the ability to produce various
documentation drawings from a 3D model.
 Produce the annotations to document various drawings
 Interpret the relationship of orthographic and auxiliary
views to their parent 3D model.
Summary
Students learn how to transfer a simple hand sketch to
communicate some aspect of a problem by creating a three-
dimensional model on a computer.

Students study basic geometrical shapes, such as
ellipses, cones, cubes and spheres, and how they are
combined to form complex geometry using the aid of the
computer. The basic techniques that students will
learn may be applied to making a
model of a human body for medical
purposes, creating a soft drink
container, or manufacturing a
starter motor for an automobile.
Students build on drafting basics by adding many
essential features to their 3D models and will learn to
document, edit, and archive drawings as well as study
techniques of adding features such as holes, slots, and
chamfers.
Finally, students will see that once they have created a
3D model of an object, the computer can show them the
model from virtually a limitless number of viewpoints,
greatly enhancing their visualization of the object as well
as being a wonderful tool for multimedia presentations.
