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

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 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 floor blocks together and adjust for permutations (0.5 Hour)
Refine differences between floors, atrium and public spaces (1.5 Hour)
- Create the cut outline of the void space
- (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

Limitations & Disclaimer

The time estimates represented in this workflow is estimated based on a specific model / input. Actual time required may vary depending on specific use scenarios.

Here the building is housing with 22 floors or about 560 beds with 60% of one bedroom, 20% of 2 bedrooms, 20% of 3-4 bedrooms.
