Saucer layout

Drag parts inside the case (Top view only). Dashed border = fixed reference, can't move. Red border = collision or spilling past the rim. ≈ = estimate, correct once you have the part in hand.

Case internal diameter (mm)

Wall thickness (mm)

Export produces a real-scale SVG (viewBox in mm). Side and 3D read the same live arrangement as Top — same-layer parts share a depth band (max of their thicknesses), a docked part adds its thickness to its host's instead of occupying its own band. Parts with a bold tick on one edge have a connector cluster that must reach the case wall for a cutout — the tick is green when it does, red when it doesn't.
