One aspect of the course is to teach us tips for Visual expression - and I started making some notes in this area as this is related to but unlike the sketchbookskool klasses (sic) I have been following.
The basics of sketching for impact
These include
- fill the frame (use the page, not a thumbnail)
- use dark lines (walk 10 paces away from your drawing)
- annotate (erase pencil marks in one direction only)
- scan to high quality (1-2k pixels on longest side, cropped, jpeg/png, and scanned in colour)
(So nothing like my notes on tracing paper in a A6 book)
Orthographic projections and Cross-sections
Orthographic Projections are 2d representations of views of the object. They are moved perpendicular facing you (side A, front, top, side B, bottom) - and give you a sense of dimensions and proportions. It is important to align the drawings so that you maintain scale and proportions.
X-sections give you a sense of the materials or set up inside your object/building - e.g. in a building, you can see where the stairs and internal doors are and in an object you can see that various materials are involved.
Two point perspectives
1 point perspective is the traditional vanishing point in the distance. This VP may be obvious or appear to be behind a wall.
2 point perspective is where you have an edge, corner and two sides which converge to two VPs on both sides on the horizon.
3 point perpective is where you look up or down a building and see the edges converge.
1. All vertical lines stay vertical
2. Circles are drawn as ellipses - use midpoints and diagonals to locate.
Drawing with emphasis , and Modelling tricks and techniques are to follow over subsequent classes.
