INTRODUCTIOIN TO ENGINEERING DRAWING: • A language of Engineers to describe a. Shape b. Size c. Fit d. Finish e. Production Process and Specification
TYPES OF DRAWING: a. Detail Drawings • To describe the shape, size, fit and finish of each and every part in detail for production purposes.
Sub-Assembly Drawings • To describe the fit and method of fastening for a small
group of components to create an assembly.
Assembly Drawings • To describe the fit and method of fastening for a group of sub-assemblies to create a larger assembly.
TYPES OF MEASURING SYSTEMS: a. English • Feet and Inches
Metric • Meters and Millimeters
DRAWING INSTUMENTS AND THEIR USES: a. Drawing Board Serves as a flat drawing surface to attach a paper to. Drafting Media • • Paper Film (Tracing Paper)
