Thumbnail sketch: Six basic types of solar shading

Shading devices shield windows and other glazed areas from direct sunlight in order to reduce glare and excess solar heat gain in warm weather. Their effectiveness depends on their form and orientation relative to solar...

From doodling to noodling, or how to take a line on a walk

Most of us doodle. We move our pencil or pen spontaneously and we do not worry much about the outcome. This loose attitude towards drawing — spontaneous, relaxing, and non-judgemental — is the ground...

Linear Perspective: the pictorial effect

You can manipulate a perspective drawing by changing certain variables, such as: moving the picture plane changing the orientation changing the station point location with respect to the object moving the horizon line up...

Passive solar design: five quick thumbnail diagrams

Passive solar heating refers to using solar energy to heat the interior space of a building without relying on mechanical devices that additional energy. Passive solar systems rely instead on the natural heat transfer processes of the...

Drafting the Mondrian’s Cube

EXERCISE #100 | The Mondrian's Cube The intent of this exercise is to develop your ability to visualise and communicate form and space by relating two-dimensional orthographic drawings to three-dimensional paraline drawings such as axonometrics and obliques. 1 ASSEMBLAGE...

How to construct a paraline circle at 45°

In paraline drawings, all circles appear as ellipses except true circles — those that appear in planes parallel to the picture plane. Follow the four-step instruction to constructing a paraline circle at 45° that recedes to the right. theoria:

Peekaboo: Plan Oblique showing Cutaway

Plan oblique at 45°-45° axes angles and cutaway I traced this plan oblique with a cutaway because it is the perfect paraline drawing when you need to show facade roof and interior details. Since the plan...

The arrow as an active linear symbol

As an abstract graphic language, arrows have great meaning in conceptual diagramming since they largely express movement and the idea of corridors. The most common active linear subjects when diagramming are automobile circulation, pedestrian circulation,...

Drawing vegetation: Hand-drawn texture trees in plan

Drawing textured trees is more realistic than simple circle shapes. Like branch drawn trees, the graphic expression of texture trees allows the viewer to see through the canopy. However, including the objects underneath the canopy...

Drawing vegetation: Hand-drawn outline trees in plan

Drawing the outline of trees is aimed at a more symbolic representation than a realistic. An outline tree has a solid, opaque appearance. Plant materials and other design elements are usually not shown underneath this...

Drawing vegetation: Hand-drawn branch trees in plan

Drawing branched trees is more realistic than simple circle shapes. The silhouette effect of these styles allows the viewer to see through the canopy. However, including the objects underneath the canopy can undermine the simplicity...

Multi-oblique combination

Multi-oblique drawings offer a world of combinatorial views. I traced a simplified version of Jaeger Beach House by Rob Wellington Qhingley as a great example of how to combine different oblique views. These sort of paraline drawings...

Arrows, bubbles, and hatches: The language of conceptual diagrams

Conceptual diagrams are derived directly from bubble diagrams. They are highly abstract and symbolic. Concept diagrams can be done with any free flowing media, such as pencil, marker, felt pen, or coloured pencils.There are no conventional symbols...

Cube judgement system and how to quickly draw in three-point perspective

Three-point perspective regards linear perspective in which parallel lines along the width of an object meet at two separate points on the horizon and vertical lines on the object meet at a point on the...
