COURSE AS VIEWED IN THE TOTAL CURRICULUM
This course is one course that students complete in the pursuit of attaining the
Manufacturing Skills Certification (MSC). This certificate curriculum was developed by
the Kansas Institute for Technical Excellence (KITE) colleges in Kansas in collaboration
with business and industry representatives within the manufacturing sector from the
Central/South Central Kansas region.
This course is not intended for transfer.
IV. ASSESSMENT OF STUDENT LEARNING/COURSE OUTCOMES
Barton County Community College assesses student learning at several levels:
institutional, program, degree and classroom. The goal of these assessment activities is to
improve student learning. As a student in this course, you will participate in various
assessment activities. Results of these activities will be used to improve the content and
delivery of Barton’s instructional program.
The student will have a basic understanding of the skills which are essential to the
success of any quality improvement or scrap reduction effort. This course uses practical
application based material that follows ANSI standards to better understand engineering
drawings.
Upon completion of this course students will be able to:
1. Describe the background information found on engineering drawings, their role in
manufacturing and the concept of multi-view representation of an object.
2. Visualize a part in a multi-view drawing, explain how the principal views are
derived through orthographic projection and how to identify related part features
from view to view.
3. Explain the purpose of sectional views, how they are obtained and their different
types, along with some of the drafting conventions that are typically applied to
sectional views.
4. Identify dimensions and tolerances, the numeric elements of an engineering
drawing, how dimensions and tolerances are commonly indicated on a drawing,
and the different tolerancing methods.
5. Contrast dimensions and tolerances, dimensioning methods, maximum and least
material condition classes of fit between mating parts, some of the symbols used
in geometric dimensioning and tolerancing, and in surface finish specifications.
6. Explain how the common part features are represented and dimensioned on a
drawing.
7. Discuss the basic terms and principles of geometric dimensioning and tolerancing
and why it has become an important engineering tool in manufacturing.
8. Specify the general format of a GD & T specification and the meaning of the
symbols it contains.
9. Differentiate between the two types of geometric characteristics in detail: form
tolerances and orientation tolerances.
10. Evaluate the three types of geometric characteristics: profile tolerances, location
tolerances and run out tolerances.

percent. The grading scale is as follows:
90 - 100 A
80 - 89 B
70 - 79 C
60 - 69 D

ATTENDANCE REQUIREMENTS
Regular attendance in class and laboratory sessions is an obligation assumed by each
student at the time of registration. It is the student's responsibility to fulfill all the
requirements of a course as prescribed by the instructor. If a student must miss a class,
arrangements should be made in advance with the instructor. Instructors have the
responsibility to provide the opportunity for students to make up, in a reasonable and
appropriate manner, work missed for a school-related activity, verifiable illness, personal
emergency, or death of a family member. A published procedure allows students to
address inequities in this policy.
