Drafting and Design Technology

Course Information Cr Hrs
DDT-100 Fundamentals of Drafting

Mechanical drafting is the graphic language used by engineers and technicians in high technical manufacuting environments.  The basic drafting skills and knowledge necessary to communicate graphically are investigated through lecture and lab opportunities using a 2D computer aided drafting system (CAD). 

DDT-110 Mechanical Dimensioning and Tolerancing

This course focuses on the interpretation and application of American national Standards Institute (ANSI) and American Society of Mechanical Engineers (ASME) Y14.5M 1994 drafting standards and rules for dimensioning and tolerancing mechanical prints utilizing a computer aided drafting system.

DDT-115 Manufacturing Processes and Materials

This lecture/lab course focuses on the study of mechanical, chemical, physical properties, and structure of engineering materials with heat treating of ferrous and nonferrous metals, and an investigation of the methods used to process these materials. 

DDT-150 Descriptive Geometry and 2D CAD

Intermediate Computer-Aided Drafting (CAD) skills are developed for graphic solutions of design problems with regard to spatial relationships using descriptive geometry to produce auxiliary, revolution, intersection and development drawings.

 Prerequisite: DDT 100.
DDT-160 Residential Architectural Drafting

Residential architecture will give the student an understanding of the basic concepts of construction and residential design. Students will produce a set of floor plans for a house. This course is based on space relationships required for the family uses of the structure, and explores basic design concepts, both for function and aesthetics.

 Prerequisite: DDT 100.
DDT-200 Production Design Drafting

This lecture/lab course will provide students with the knowledge and skills in the use of current 3D computer aided design (CAD) systems with individual and group projects utilizing the design method, the engineering design cycle, and the access and application of standards and engineering data for the production of mechanical working drawings.

 Prerequisites: Grade of "C" or better in DDT 110 and EGR 100 or concurrent enrollment.
DDT-210 Structural Steel Detailing and Drafting

Computer-Aided Drafting and design proficiency is increased through the design and detailing of structural steel projects of buildings and bridges for heavy construction industries.

 Prerequisites: DDT 100.
DDT-250 Project Design and Manufacturability

This capstone course will simulate a real world mechanical design working environment, providing students with an opportunity to display acquired knowledge and skills. Students will apply the design method and produce working drawings that include detail, assembly, bill of material, specifications, and three dimensional (3D) models utilizing current 3D CAD solid-modeling software and 3D printer.

 Prerequisite: DDT 200.
DDT-260 Commercial Architectural Drafting

This course focuses on the study of the basics of architectural drafting on the (CAD) system, and how it applies to commercial buildings. A study of the considerations required for the commercial layout.

 Prerequisite: DDT 100.
DDT-270 Civil Engineering Drafting

A CAD system is used in the production of topographic, mapping, site plan, sewer plans and road drawings.

 Prerequisite: DDT 100.
DDT-290 Co-Operative Ed/Intern/Related Elective

This course entails a supervised work experience in the major fi eld which provides the student with the opportunity to make practical application of the knowledge and skills attained in coursework. An individualized instructional management plan will determine goals to be accomplished. Seminars may also be required.

 Prerequisites: Completion of 30 credit hours and 2.0 GPA or advisorís approval. Please see the Department Chair of the specific program area for application.
