Check courses offered at your local community college; many community colleges offer technical courses. For example, Fulton-Montgomery Community College in Johnstown, N.Y., offers three courses: Introduction to Architectural Drafting, Computer Aided Drafting and Intermediate Architectural Drawing, each lasting two hours per week. Most community colleges require only a high school diploma or GED to enroll.
Review the training and continuing education available from industry groups such as the American Design Drafting Association (ADDA). These groups may have a local chapter near you or offer online drawing courses. Industry groups also usually have an annual conference, where you can take multiple courses over a few days' time. Members of the group can also serve as referrals and provide recommendations on training programs.
Search through the education or textbook section of an online or brick-and-mortar bookstore to find textbooks such as "Mechanical Drawing: Board and CAD Techniques" or "Mechanical Drawing: A Manual for Teachers and Students." Use the books to study at home on your own pace.
Participate in an online webinar, which is a live or self-paced learning session conducted over the Internet. Topics include "Plant Layout with SolidWorks CAD Software" and "Untangling the Challenges of Electrical Mechanical Design." Other webinars are available for you to download and undertake when time permits.
