|Student Learning Outcomes -|
- Select proper materials to construct simple models and forms and justify selections.
- Create three-dimensional sketches by drafting simple primitives and applying proper line conventions.
- Interpret and use industrial specifications and engineering standards for the safe selection and application of appropriate model making techniques and equipment.
|Description - |
|Introduction to the principles of three-dimensional design as they relate to model making for 3D printing and rapid prototyping applications. Students will develop forms and shapes using a variety of materials and model-making techniques, with an emphasis on plastic and metal processes. In addition to modeling with basic materials, students begin to develop skills using quick, visual model-development materials, including foam core, cardboard and clay.|
|Course Objectives - |
|The student will be able to: |
- Generate drafting designs of simple primitives including cubes, spheres, cones, and cylinders utilizing standard techniques.
- Select and apply proper line conventions to create three-dimensional sketches.
- Create thumbnail and concept sketches using various digital visual communication techniques.
- Interpret and use industrial specifications and engineering standards while completing laboratory case studies requiring selection and application of techniques and equipment.
- Select proper materials for optimum application and safely setup and use basic wood, metal, and plastic forming equipment to construct models.
- Build simple clay and plaster molds and develop quick shapes and forms by utilizing paper and plastic sheet materials.
