What you're learning in this topic
Learning intention WALT
We are learning about sketching & illustration, specifically to:
understand
- illustration techniques: light, shade, shadow, reflection, tone and texture
be able to
- sketch in proportion with good line quality, using crating
- sketch pictorial and orthographic views from given drawings, with hidden detail
Success criteria WILF
- I can sketch in proportion with good line quality, using crating
- I can sketch pictorial and orthographic views from given drawings, with hidden detail
- I can describe illustration techniques: light, shade, shadow, reflection, tone and texture
Sketching skills
- Proportion: sizes look right relative to each other. Compare widths and heights before you start.
- Line quality: light construction lines first, then firmer, darker outlines. Construction lines must look different from outlines.
- Crating: sketch a box the overall size, then cut away or add to it.
- Vanishing points: for perspective, keep depth lines heading to the VPs.
- From orthographic views: be able to sketch a pictorial from given elevations and plans, and orthographic views from a pictorial, in third angle with hidden detail.
Assignment sketching rules
- No drawing boards, set squares or drawing equipment: using them gives 0 marks for the whole sketching task. A straight edge is allowed.
- Digital sketching: straight edge tool only. No shape or circle tools, and no software that turns a 3D model into a 2D sketch.
- Don't model the object in CAD and copy it: the task assesses your ability to interpret the object.
- Show the elevation in the direction the data sheet indicates.
Illustration techniques
- Light source: decide where the light comes from; faces towards it are lightest.
- Tone: graded light to dark shading that shows form.
- Shade and shadow: the dark side of the object, and the shadow it casts on the ground.
- Reflection: streaks and highlights on shiny surfaces such as glass, metal and gloss plastic.
- Texture and material: wood grain, brushed metal, fabric.
- Gradient: a smooth change of colour or tone.
