design communication
mixed media & rendering
drawing can be embellished with colour, tone & shadows to create depth, texture & show surface finishes
mixed media representation - can combine pen, pencils, spirit markers, chalk & water colour
increasingly CAD packages can achieve similar effects more rapidly in a more versatile format - making alterations & different colour schemes & finishes
-
texture rendering
-
-
typical textures include: wood grain ,cross-hatching & stippling
presentation drawings - often use these to bring ideas to life so clients get best idea of what it will look like
1 point perspective
sketch:
simplest style, that you may sketch in notebook, but use is limited
-
-
advantage - designs can be viewed from different angles, determined on whether the drawing is stated above or below the horizon line or to one side or the other of the vanishing point
-
2 point perspective
uses 2 vanishing points, so shapes that project towards them look smaller
-
-
-
-
-
Sectional drawings
these truncate an object at a given point to show internal features that are otherwise hidden from view
-
-
-
-
Data vs ideas
-
data
priorities include things like dimensions, specifics of fits and angles, etc
initial ideas
giving a sense of what the final product may look & feel like, vague starting point, not many specifics needed
-
3 point perspective
-
-
the nearer to the 3rd vanishing point to the centre of drawing the greater the distortion - can create extreme point of view, which can make for striking effect in architectural design
-
clear communication
generated by hand or using CAD software, various visual tools are used to simplify complex info
-
-
-
-
-
technical drawing
once ideas are finalised, dimensions & assembly details must be communicated to the manufacturer
-
orthographic projection, cross-sectional & exploded views are ideal for this stage of design development
dimensions & conventions
-
line styles & symbols are used for different features, e.g. hidden, solid or central features
-
built to scale
-
standard conventions are used in these drawings to show dimensions & structural details clearly with minimal text
by building to scale you can refer to measurements to during manufacture to ensure you're making accurately
-
make or break
in summary, technical drawings like these are vital to take a product from a concept to reality
they allow material quantities & costs to be calculated & demonstrate how a product & its components interact
they ensure equipment can be set up accurately & within tolerance to produce safe, high quality products that are fit for purpose
2D drawing
Sectional drawing
used to show internal, hidden details of a product
