About
I. Intro: -Define engineering drawing (Japan focus). -Know freehand vs. technical. -Recognize sketching benefits. -Identify basic tools & triangle scale use. -Understand standard line types (brief JIS). -Practice basic sketching control & posture. II. Geometric Constructions (with Scale): -Sketch proportional basic shapes. -Develop visual scaling. -Visually divide lines/shapes (scale). -Sketch parallel/perpendicular (scale). -Sketch tangents/arcs (radius & scale). III. Orthographic (1st Angle, Japan, with Scale): -Understand orthographic views & scale. -Apply 1st Angle (Japan) & scale. -Sketch scaled principal views. -Use scale for sketch check. -Transfer scaled dimensions. -Represent features with scale. IV. Isometric/Oblique (Scaled Estimation): -Understand pictorial views & scale. -Sketch isometric (isometric scale). -Briefly sketch oblique (scale). V. Dimensioning & Tolerancing (Freehand, Scale): -Understand basic dimensioning (brief JIS, scale). -Represent scaled dimensions freehand. -Understand basic tolerance (visual scale). VI. Section Views (Freehand, Scale): -Understand section view purpose & scale. -Represent scaled cutting planes. -Represent scaled section lines (hatching).
