Fabrication data
Perforated diamond cassette — at 600 × 400 mm in 4 mm ACM, this family unfolds into a 714.1 × 519.6 mm flat pattern with 11 folds, all grooved from the back: no pass on the coated face. A 1,500 × 3,200 mm sheet holds 12 of them, for 22.3 % waste.

Computed by the engine at the default parameters, on 4 mm ACM and the reference router. Your own machine and material profiles change these values in the studio.

Manufacturing constraints
- The return must exceed the groove width plus half the bend deduction, or the groove eats into the return.
- Facet-to-facet folds are grooved with the smallest cutter of the profile, V left open: the angle is held by the geometry. The angle between two facets must not exceed that cutter’s apex angle.
- Vertical returns, all tabs flat in the −D plane (rail mounting). The facet-to-return fold is 90° ± slope: below 90°, the 90° cutter is left open and the return is held by the riveted tab; above 90° (facet descending towards the edge), a wider cutter (60° nominal = 120° apex) or the machine profile’s overfold tolerance is needed.
- Every raised vertex requires a V-slit to the edge (a flat sheet has 360°, the relief less). Near the vertex the slit is narrower than the contour tool: it is cut along its axis and the tool bites each facet by up to Ø/2.
- Tabs are shortened at every corner and every kink of the edge so they never collide behind the panel: by (return + 2 mm), and more on a sharp corner, where the bisector must be cleared (tab width ÷ tan(angle/2)). An edge too short gets no tab.
- Truss bars must exceed the contour tool diameter and the fold margin must cover the groove width: a hole smaller than the tool is reported, not machined.
