Writing a brief for editable 3D design

Describe a model through objects, dimensions and relationships so that the result can be inspected and revised.

Name the result and its scale

Begin with the object or place you want to design and the scale at which it needs to work. A chair, a restaurant and a station need different levels of detail. Say which dimensions are known and which can be explored.

For example: describe a restaurant interior, identify a measured room width, name the existing booths and say that their positions must remain fixed. This gives a clearer starting point than asking for a beautiful restaurant without any constraints.

Separate fixed requirements from choices

List what must remain, what can move, and what needs clarification. Use measurable relationships where possible: an opening centred on a wall, a component aligned with another, or a clear space between objects.

If you supply references, explain the role of each one. A photograph might communicate appearance, a plan might establish arrangement, and a measured drawing might supply dimensions. Avoid silently treating all references as equally precise.

Review before the next edit

Use a perspective for the overall composition, then check plans, sections, dimensions and object types for the decisions that matter. Ask for one coherent change and restate the constraints that still apply.

Cartesian's public examples let you inspect sample files while preview access is being opened through the waitlist. Start with a bounded study, record the observations that matter, and use them to write the next brief.
