Isometric Drawing, Still Image Representation

Objectives

• Show spatial depth, project movement in space.
• Show activity in the process of happening.
• Show shadows, how light goes through the building.
• Site relationship to the context, what is happening in the background, which other buildings are present, how it relates to the street.

Prerequisites

• Set up Rhino layers
  • • Set up ten different linework types

      • CUT -  Heaviest lines. refers to structure and main wall being cut at about 4ft from finished ground level

      • SPATIAL  - Medium lines. linework geometry beyond the cut plane reflecting a spatial edge

      • SURFACE  - Light lines. (optional) division between co-planar geometries - for example joints on floor finishes

      • GLAZING  - Medium lines. cut line corresponding to transparent glazing

      • FURNITURE - Light lines. projected geometries of furniture below cut plane

      • PEOPLE - Light lines. projected geometries of occupants below cut plane

      • VEGETATION - Light lines. flora below cut plane

      • BELOW - Lightest lines. very light lines reflecting background context geometries beyond cut plane.

      • ABOVE - Light, dashed lines. dashed lines corresponding to significant geometries above

      • HATCH - Variable lines depending on hatch type. layer to host hatch geometries

1. Prepare the linework (

0.5 Hour)

• Cut the plan where you will draw the section and rotate
• Add the cut line (longest line in diagram) then add the following lines
• 1m below the line for the second linewidth (spatial)
• 3m below that second line, add a third line for the third linewidth (surface), below that will be everything that remains in the lightest color, maybe furniture layer
• About 3m above the cut line add two lines which generate the height of each floor, from floor below to floor above

• Once these are added, start reporting all of the lines of the objects which intersect the cut plane line
• Produce one construction line from the deepest part of the plan and copy along the cut line axis to go faster
• Reproduce process for the different floors for which you have a plan
• Lock the layer of these construction lines

2. Drawing vertical lines (

0.5 Hour)

• Do all plans at once in this fashion
• Start drawing the lines from floor to ceiling (spatial layer)
• Add the cut lines
• Add the surface lines

3. Populating section (0.5 Hour)

• Create block for handrail unit
• Add handrail unit block to section
• Repeat above for doors / windows / furniture / other repeated architectural elements in section
• Add stairs
• Add hatches

4. Updating particular spaces (

2 Hour)

• Create block for individual floors
• Repeat block for each repetitive floor
• Assemble all individual sections together (30minfloor blocks together and adjust for permutations (0.5 Hour)
• Refine differences between floors, atrium and public spaces (70min1.5 Hour)
• Create the cut outline of the empty void space
• Put everything in it as light background
• Add a thin hatch to differentiate the zone from the others

Image Removed

• (optional) add light transparent hatch to differentiate continuous void spaces
• As the void spaces are not repeated per floor, this area requires the highest level of manual drawing and should be allocated the largest amount of time
