DRA 132 - Architectural Computer Drafting (3 credits)
Prerequisites: BCT 110, BCT 120, DRA 190 or divisional permission
Using architectural software, students produce professional drawings; compile contract documents; and date, store and retrieve information on both two- and three-dimensional projects. Involves creation of walls, doors, windows and roofs as well as implementation of symbols for structural, electrical, mechanical, plumbing, furnishing, and site work. 2 lecture/2 laboratory hours

DRA 190 - Introduction to Computer-Aided Drafting (2 credits)
Introduction to the use of the computer as a drafting tool. Includes concepts, terminology, and basic commands necessary to prepare drawings using CAD software. Requires basic knowledge of the computer keyboard. 1 lecture/2 laboratory hours
course outline

DRA 191 - Introduction to Building Information Modeling (2 credits)
Introduction to the use of the computer using building information modeling software. Topics include basic terminology and concepts of modeling, geometry, and the basic commands necessary to prepare a building model and several drawings. 1 lecture/2 laboratory hours
course outline

DRA 216 - Heating, Refrigeration and Air Conditioning Drafting (3 credits)
Prerequisites: ENT 116 or permission of instructor, HRA 102
Study of the aspects of drawing needed by a drafter in order to prepare finished drawings for the installation of heating, refrigeration, and air conditioning systems. Intended primarily for students in the Heating, Refrigeration and Air Conditioning program. [occasional offering] 1 lecture/4 laboratory hours

DRA 217 - Structural Steel Design and Drafting (3 credits)
Prerequisites: ABT 120, DRA 190
Corequisite: CIV 237
Examines the problems common to structural design of steel and similar materials relative to the architectural frame of a structure.

Requires familiarity with general steel design codes and the preparation of structural drawings. 2 lecture/3 laboratory hours
course outline

DRA 218 - 3-D Modeling / 3-D Printing (3 credits)
Prerequisite: MET 122 or advisor permission
An introduction to 3-D solids modeling and printing software. Students build a prototype model using SolidWorks software and print a 3-D model to explore the basic size and look of a product or machine part. Orthographic drawings with dimensions are also produced for part building using traditional machining techniques. 2 lecture/2 laboratory hours
course outline

DRA 238 - Advanced Computer-Aided Design (3 credits)
Prerequisite: DRA 190
Advanced computer drafting course using CAD software. Includes a review of basic command options, display options, hatching and sectioning, text, and dimensioning. Introduces 3-D drawing and surface modeling. 2 lecture/2 laboratory hours
course outline

DRA 248 - Advanced Building Information Modeling (3 credits)
Prerequisite: DRA 191 with a minimum C grade
Advanced computer-aided design and drafting using BIM software. Students build intelligent 3-D models of designs using parametric, feature-based modeling software. After refinement, 2-D drawings are created from the 3-D model. 2 lecture/2 laboratory hours

DRA 251 - Solids Modeling (3 credits)
Prerequisite: DRA 238 with a minimum C grade
An introduction to solids modeling and rendering software. Students explore the capabilities and potentials of computer software used to construct solids models then render the resulting image. 2 lecture/2 laboratory hours
