Career & Technical Education Sketching 2.00 Explain and demonstrate basic sketching skills and techniques.
Career & Technical Education Sketching Concepts 2.01 Explain the concepts related to sketching.
Purpose of a Sketch Quickly & easily get an idea on paper Design sketches Freehand technical sketches Technical illustrations
Freehand Technical Sketch
Sketching Materials Paper Pencil Soft lead Optional Eraser Grid Paper
Sketching Technique Proportion Clarity Sketching Aids
Sketching Lines Vertical lines Top to bottom Long straight lines Series of short straight lines
Sketching Circles & Arcs Begin by lightly constructing a square
Sketching Angles Begin with 90 ° angle 60 ° 30 ° 45 ° Subdivide onceSubdivide twice
Career & Technical Education Sketching 2.02 Explain the concepts and principles underlying isometric, oblique and multiview sketching.
Sketching Types of Sketches Single-view Multi-view Pictorials
Single-view Sketching Technical purposes Front view Most descriptive features
Steps for Single-view Sketching Object Step 2 Step 1 Step 3Step 4
Multi-view Sketching Technical sketch Front view Top view Side view
Multi-view Sketch TOP VIEW R. SIDE VIEW FRONT VIEW
Single-view/Multiview Sketch Assignment
Pictorial Sketches Quickly communicate an idea Three dimensions in one view Width Height Depth
Pictorial Sketches Three (3) types Isometric Oblique Perspective
Isometric Sketch WIDTH DEPTH HEIGHT
Isometric Sketching Three equally spaced axes of 120 °
Isometric Sketching Receding lines Typically 30° off horizontal
Isometric Sketching Circular shapes appear as ellipses
Isometric Ellipses Correct ellipse orientation
Isometric Sketching Non-Isometric lines Locate endpoints and connect
Isometric Sketching Assignment
Oblique Sketch WIDTH DEPTH HEIGHT
Oblique Sketching Front view is drawn true shape and size
Oblique Sketching Receding edges are usually drawn at an angle of 30°, 45°, or 60°
Oblique Sketching Circles and curves drawn on frontal plane will appear true shape and size
Oblique Sketching Assignment
Perspective Sketches 2-Point Perspective1-Point Perspective
Perspective Sketches Objects appear as the eye would see them Most realistic type of pictorial sketch Most difficult pictorial sketch to draw
