Drawing as an instrument, not an output
On why the studio still sections everything by hand before it is modelled, and what gets lost when the first act of design is a render.
A section drawn by hand forces a decision about thickness at every line. A model built to be rendered postpones that decision indefinitely, and the postponement is usually permanent.
The value of the drawing is not the image it produces. It is the sequence of small commitments it demands: this slab is this deep, this opening starts here, this wall carries and this one does not.
Digital tools then do what they are good at: coordination, quantity, tolerance and repetition. The order matters. Drawing decides; modelling verifies.
