In this module students use computer-aided drafting (CAD) software to explore the fundamentals of drafting. Students use a CAD software to create multiview drawings of geometric solids. Finally, Students use the CAD software to complete and evaluate a floor plan for a self designed house.
- In this module, students use computer-aided drafting (CAD) software to explore the fundamentals of drafting. A common tool for engineers, architects, landscapers, and even prospective home builders. CAD software is an invaluable tool for those who work in a three-dimensional environment. Students explore this type of design by creating mulitview drawings of a geometric solid. Then students use CAD software to complete floor plans. They evaluate their floor plans based on standards for architectural drawings and on a 3-D computer “walk-through” of their floor plans.
- *Explore engineering and architectural drafting with the use of a CAD software
- *Explore careers related to each type of drawing
- *Use a CAD software to become familiar with the language of drafting. Among the terms and items covered are alphabet of lines, dimensions, views, and various symbols for materials.
- *Complete a mechanical drawing with the use of a CAD software.
- *Complete an architectural drawing the use of a CAD software.
- *Create a three-dimensional model with the use of a CAD software.
- *Expand reading and research skills by using books, software programs, and interactive multimedia to complete module research challenges and applications.
- *Enhance mathematical skills by solving problems related to CADD
- *Experience teamwork, time management principles, and cooperative and collaborative learning in a self-directed system designed to increase motivation and self-confidence.
Students complete three primary activities. During “Introduction to CADD” students define the term CADD, give examples of occupations in which CADD is used, and identify and explain hidden, border, and object lines. In “Multiview Drawings” students create and dimension a multiview drawing of a geometric solid, and explain the phase orthographic projection and why only three views are typically used in a multiveiw drawing. During “Floor Plan Completion” students create and print a floor plan for a house, explain the various symbols in a floor plan, evaluate the floor plan indicating how it can be improved, and demonstrate and explain how to find the dimension of a room from the information on the floor plan.
