Drafting and Design Engineering Technology

The Drafting and Design Engineering Technology (DDT) program of State Technical College of Missouri is thorough and comprehensive, with a balanced mix of instruction in mechanical, architectural, civil, electrical, and structural drafting. The DDT program has been awarded program certification by the American Design Drafting Association (ADDA), a nationally-recognized professional drafting association, which assures a high quality program that benefits both education and industry. The DDT program is also accredited by the Association of Technology, Management, and Applied Engineering (ATMAE).

After a brief introduction to manual drafting techniques, drawings are produced using computer aided drafting (CAD). Using engineering data, specifications, and various equipment, drafting and engineering technicians assist in determining design changes and production costs. They may also be required to apply their knowledge to solve particular design problems such as those involving tolerance, stress, strain, bending, and compression.  The department has two state-of-the-art CAD labs with the latest versions of software used in industry.  Students are scheduled in small classes to ensure individual attention and high quality instruction.

Graduates of this program are qualified to take positions as industrial and architectural designers, drafting and engineering technicians, cost estimators, and quality assurance technicians. Drafting, design, and engineering technicians often assist engineers and architects with design and development work.  Most drafting and engineering technicians work from rough sketches, specifications, and technical data furnished by engineers. Their job is to transform these ideas into precise drawings. Drafting and engineering technicians use handbooks and tables for computations concerning strength, reliability, and cost of materials.

Due to the green revolution, there has been a fundamental change in the way building projects are approached. Today’s skilled drafting and engineering technicians need to understand the fundamental concepts associated with improving environmental performance on every project. The Drafting and Design Engineering Technology program contributes to the green economy by emphasizing the fundamental concepts of sustainable design, green building practices, and why sustainability is important. The program also expands the discussion of green building strategies and technologies by studying the methods being used worldwide.

Enrollment in the Drafting and Design Engineering Technology program is limited and students are selected for this program on a competitive basis. Contact the Office of Admissions for the specific application requirements and deadline.

It is a graduation requirement of the Drafting and Design Engineering Technology (DDT) program for students to earn a grade of “C” or better in all “Core Curriculum” courses.
