Isometric Drawing, Still Image Representation

Objectives

• Show 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

• Existing 3D model of building

• Make sure all surfaces are continuous and all pieces are aligned, this is done by making sure all curves are continuous before they become extruded
• Make sure you don’t have any open faces in the model, only solids
• Window planes should be individual elements between moleons, avoid continuous plans through other objects. Same for columns, have sets of columns for each floor, instead of continuous ones through the building
• Camera settings - 1-point perspective, 35-50mm

• Set up 3-4 new layers

• Cut
• Foreground
• Background
• Other (structure, particular objects of interests…)

Project sepcifities

• 22 floors
• 560 beds with 60% of one bedroom, 20% of 2 bedrooms, 20% of 3-4 bedrooms

Prepare the linework (25min)

• Cut the plan where you will draw the section and rotate
• Add the cut line 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
• Produce one 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 lines

Drawing vertical lines (15min)

• 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

Drawing horizontal lines (35min)

• Add horizontal lines of handrails (create a block first)
• Add doorways and windows (create a block first)
• Add block furniture
• Add stairs
• Add hatches

Updating particulare spaces (100min)

• Assemble all individual sections together (30omin)
• Refine differences between floors, atrium and public spaces (70min)
• Create the cut outline of the empty space
• Put everything in it as light background
• Add a thin hatch to differentiate the zone from the others
