Perforated diagonal fold
A corner-to-corner fold with, on the main facet, a grid of round holes whose diameter shrinks along the diagonal. Perforated facets, pattern, pitch and gradient are adjustable.

Fabrication data
Perforated diagonal fold — at 600 × 400 mm in 4 mm ACM, this family unfolds into a 758 × 558.8 mm flat pattern with 9 folds, all grooved from the back: no pass on the coated face. A 1,500 × 3,200 mm sheet holds 8 of them, for 38.6 % waste.

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.
- Holes at the given pitch: the largest hole is reduced to keep at least the contour tool diameter of material between neighbours; every hole fits inside the facet minus the margin. Holes smaller than the contour tool are drilled (PERCAGE layer).
- The edge margin must cover half the bend deduction (the fold axis moves into the facet) plus half the widest groove, or a hole bites into the V-groove.
