Design Drafting Technology

15.1301

(Associate of Applied Science Degree)

Linn State Technical College’s Design Drafting Technology (DDT) program has been awarded program certification by the American Design Drafting Association (ADDA), a nationally recognized professional drafting association, which assures a quality program that benefits both education and industry. The DDT program is also accredited by the Association of Technology, Management, and Applied Engineering (ATMAE). Graduates of this program are qualified to take positions as industrial and architectural designers, engineering technicians, cost estimators, and quality assurance technicians. Drafting and design technicians often assist engineers and architects with design and development work.

Drawings are produced by using standard drafting equipment or by using computer aided drafting (CAD).  Using engineering data, specifications and various equipment, drafting 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. 

Most drafting technicians work from rough sketches, specifications and technical data furnished by engineers. Their job is to transform these ideas into precise drawings. Drafting technicians use handbooks and tables for computations concerning strength, reliability and cost of materials.

The Design Drafting Technology program of Linn State Technical College is thorough and comprehensive, with a balanced mix of mechanical, architectural, civil, and structural drafting. The department has two state-of-the-art CAD labs with AutoCAD, Autodesk Inventor, SoftPlan, Autodesk Revit, and MicroStation software. Students work on traditional drawing boards and networked PC’s. Students are scheduled in small classes to ensure individual attention and quality instruction. The Associate Degree program is rounded out with supporting math and communications courses. A drafting internship is available for students after the completion of specific course work. An internship is not a program requirement for graduation.

Due to the green revolution, there has been a fundamental change in the way building projects are approached. Today’s skilled drafting technician needs to understand the fundamental concepts associated with improving environmental performance on every project. The Design Drafting 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 Design Drafting 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 Design Drafting Technology (DDT) program for students to earn a grade of “C” or better in all “Core Curriculum” courses.

Program Mission
The Design Drafting Technology program is a technical program constructed to provide to the students the opportunity to develop technical knowledge, drafting skills, math skills, and effective communications skills which enable them to take positions in industry as industrial and architectural designers, engineering technicians, cost estimators and quality assurance technicians in the fields of mechanical, architectural, civil, and structural drafting.

Program Goals
The goals of the program are to:

• Assure that the student is given the opportunity to attain the technical knowledge to transform ideas to precise drawings using problem-solving skills.
• Assure that the student is given the opportunity to attain the drafting skills, by manual and computer methods, using state-of-the-art equipment and software.
• Assure that the student has the opportunity to attain math skills to solve design problems and compute strengths, reliability, and cost.
• Assure that the student has the opportunity to attain effective communications skills.
