Understanding AI-generated assumptions

When a request leaves out a value the design needs, the assistant picks a sensible default and lists it under Assumed (check these). Nothing is assumed silently.

Common assumptions

Assumption	Why it matters	How to change it
Material and thickness	Joints, slots and the minimum detail size depend on it	Clear the selection; Material in the right panel
Overall size	Decides the price tier, sheet fit and text size	Select the object; Width / Height
Hole diameter and margin	Screws and cord must fit; holes too near the edge break	Select the hole pattern; Pattern settings
Text size	Small engraved text can become unreadable	Select the text; Cap height
Process	Decides layers, file formats and allowed materials	Fabrication → Process

Before you buy

Open Check & output. The engine's own assumptions — inside dimensions of a box, divider slot widths, the thickness used for joints — are listed under the price. These come from the geometry, not from the assistant, and are what the files are built from.
