EDD 101 - Engineering Drawing 1
Credits: 3
4 Skills Lab Hours
Description
This is a course in basic drafting techniques used to produce engineering drawings. Conventional drafting and dimensioning practices as outlined by the National Occupational Skill Standards, American National Standards Institute (ANSI) and International Organization for Standardization (ISO) will be used to produce orthographic drawings, pictorial drawings, auxiliary views and section drawings. Technical drawings will be completed using freehand sketching techniques, conventional drawing tools and CAD.
Learning Outcomes
Upon successful completion of the course, the student will:
- Identify the types of lines used in technical drawings and technical sketches.
- Identify the basic tools used by drafters.
- Create sketches of both two and three dimensional objects using correct sketching methods.
- Sketch the primary views of an orthographic drawing in proper orientation and alignment.
- Draw the six standard views of an object using proper conventions, placement and alignment.
- Describe the concept of sectional views.
- Explain the purpose of cutting-plane lines.
- Describe the difference among multiview projection, axonometric projection, oblique projection and perspective drawings.
- Create an isometric drawing and an oblique drawing.
- Prepare a fully annotated engineering drawing using conventional dimensioning techniques as required by the ANSI and ISO drafting standards.
- Explain the difference between aligned and unidirectional dimensioning systems.
