FAQ
Frequently Asked Questions
Not exactly. 'Mechanical drawing' refers to the type of precise, technical illustration. Historically, it was done by hand (manual drafting). Today, such drawings are almost exclusively created using CAD software, so a 'CAD drawing' is the modern method of producing a 'mechanical drawing'.
Mechanical engineers, industrial designers, machinists, toolmakers, drafters, architects (for structural/mechanical systems), and patent attorneys all work with mechanical drawings.
Traditional tools include a drafting board, T-square, set squares (triangles), compass, dividers, scales, and technical pens of various widths.
Many educators believe it is, as it provides a fundamental understanding of projection, scale, line weights, and dimensioning that is essential for creating effective and clear digital drawings later.
