Portland Community College | Portland, Oregon

Upon successful completion students should be able to:
1. Competently apply drawing and modification commands.
2. Create 3-Dimensional solid models using AutoCAD software.
3. Create technical mechanical assembly drawings using multiple solid models.
4. Generate paper space layouts from model space geometry.

This course will be presented by means of short lecture/discussion sessions and laboratory projects. Individualized instruction will be provided while the student is working on assigned projects. Open laboratory time will be made available, and may be necessary to complete the given tasks.

Individual and full class discussion; lab drawing assignments; exams; and final project deliverables may be used to assess outcomes.

THEMES, CONCEPTS, AND ISSUES:
 

• Industrial, manufacturing, mechanical and other drafting technology students must be able to visualize and graphically reproduce complex layouts to succeed in subsequent drafting and design courses.
• Drafting Designers and Engineers need to be able to communicate with each other, and with manufacturing and construction personnel, using graphical representations of physical objects.
• AutoCAD design software is widely used in the drafting technology professions.
• Many drafting graduates enter the workplace by performing computerized graphics manipulations.

COMPETENCIES AND SKILLS:
The student will be able to:

• Communicate effectively using computerized graphical techniques.
• Demonstrate intermediate to advanced competency using AutoCAD graphics software.
• Create solid models for use in subsequent drafting courses or within industry.
• Create a portfolio of AutoCAD drawings to demonstrate their abilities.
