Introduction to Design Sketching

Develop line drawing skills through grid and connect-the-dots exercises that build muscle memory, using either worksheets or blank pages as warm-ups for consistent practice.

Master value in sketching by building a gradient with a ballpoint pen, creating a range of tones from light to dark. Practice varied marks to develop muscle memory for lessons.

Explore how perspective projection turns three-dimensional objects into readable two-dimensional drawings, using foreshortening to control realism. Compare orthographic, one-, two-, and three-point perspectives to communicate design ideas efficiently.

Master planar deformations in two point perspective by turning planes into boxes and curved forms, using line weights, verticals, and cross sections, with practice doodles and assignments.

Demonstrates drawing a stapler from a center line cross section, using a vertical plane, extrusion, and mirrored depth to achieve perspective with construction lines and silhouette refinement.

Explore ellipses as perspective circles, using minor and major axes and degree to shape outlines for boxes and cylinders in two-point perspective.

Build muscle memory through repeated ellipse drawing drills, tracing templates and progressing from narrow ellipses to circles, while maintaining the major axis at 90 degrees to the minor axis.

Explore three approaches to drawing cylinders: start with a constructed box and ellipses, then a major/minor axis method in perspective, and finally a quick ellipse-based method, with practice cues.

Master box deformations in design sketching by building additive and subtractive changes in two-point perspective, extending lines, beveling edges, and adding holes to create complex shapes.

Learn to draw cylinder shadows by using top and bottom ellipses with major and minor axes, casting parallel lines, and shaping a distorted ellipse for sunlight and point light source.

Apply lighting principles to a complex shape by projecting shadows onto the ground plane using a chosen direction and angle, and connect points to reveal the shadow.
