This document contains 55 multiple choice questions and answers related to engineering drawing and technical drawing concepts. Some key topics covered include: common units of measurement in technical drawings, different types of lines and their meanings (visible, hidden, center), orthographic projections and how 3D objects are represented in 2D views, principles of first angle and third angle projection, different types of sections (full, half, quarter), geometric shapes and properties (spheres, cylinders, cones), and basic concepts of dimensioning. The questions are designed to test fundamental understanding of core technical drawing principles and terminology.
