Examples

Checked live, not staged.

Eight sample parts: one per manufacturing process, a multi-part assembly, and one housing checked against every process. Every finding comes from Buildable's own detectors, checked live through the per-process engines. No fabricated numbers, no invented customer story; this gallery will only grow with permission from real customers.

Interactive example Assembly interference

A 13-part compact linear actuator: housing, end plates, lead screw, motor mount, coupler, carriage, guide rails, fasteners. The motor coupler was drawn without accounting for how far the motor mount's registration boss reaches back.

Parts13 solids, split from one STEP compound

Interference found1 pair, 550.1 mm³ overlap

BasisTrue boolean intersection via the CAD kernel

ConfidenceMeasured directly

Why it matters: the motor mount and the coupler sleeve cannot both exist as designed. In a physical build, the coupler cannot seat where it is drawn.

Interactive example One part, five processes: the CH-90 controller housing

A controller housing for a small industrial actuator: an open box with a raised connector end, PCB standoffs, a card slot formed by two ribs, a cable-entry boss and a snap lip under the rim for a clip-on lid. Drawn as an engineered part first, then given six deliberate design errors, each mapped to one of the app's own checks. The same geometry is a different problem for every process, and the checks say which.

For printing (FDM, SLA)The standoff walls are bored too thin; the snap lip reads as an unsupported bridge and an overhang

For machining (CNC)A rib block with no radii, so every internal corner is one an end mill cannot cut; a slot too narrow for its depth

For moulding and castingNo draft on any wall; a solid boss that reads as a thick section; the lip is an undercut on the pull axis

The referenceThe same part drawn right: every check ran and found nothing to flag, so it reads Ready to review on every process in the comparison (FDM, SLA, injection moulding, casting, CNC)

Why it matters: the fixes the app can apply here were run for real and rechecked by the same detectors. Some findings improve, one fix changes the geometry without improving anything, one leaves the part exactly as drawn because no orientation the app scored was better, and none is resolved. The reference is the part drawn right, not what the fixes produce. The measured figures, per process and per fix, are on the homepage and the manufacturing page.

Interactive example FDM: a recheck, not a rubber stamp

A wall-mount sensor bracket: a cantilevered shelf overhangs the mounting plate, and a support rib was drawn too thin. Reorienting the part is the standard first move, and Buildable shows honestly how much it helps, not a rubber-stamped "fixed".

FindingsOverhang, thin wall (0.6mm), bridge (64.4mm span)

Overhang area at the default 45° threshold, before → after reorient1,360.2 mm² → 872.6 mm² (36% less)

What reorient did not fixThin wall unaffected; bridge span still 46.9mm

ConfidenceMeasured directly

Why it matters: auto-orient helps overhang, and Buildable says so honestly, without pretending it also solved the thin rib or the cantilever it did not touch.

Interactive example Injection moulding: the same shape, a different reality

A consumer-electronics-style housing shell, walls modelled with no draft at all: fine for a printer, a problem the moment the process changes to a mould that has to release the part.

Draft736 flagged triangles, 0° walls

Wall uniformity74 hits, worst reading 14.0mm vs a 2mm median

Undercuts1 feature, 8mm void height

BasisDraft: each facet's normal angle against the pull axis (rule-based, 1° threshold). Wall uniformity: ray-cast thickness sampling. Undercut: ray-grid surface crossings.

Why it matters: without draft, a mould cannot release the part without scraping or sticking. This is Buildable's process-aware intelligence, not a generic checklist.

Interactive example CNC: ten features flagged, none of them critical

A precision machined mounting plate with an unfilleted rectangular pocket: plenty of sharp internal corners no round end mill can reach, plus one pocket cut deeper than its width comfortably allows.

Checks applicable2 (tool access, deep pockets)

Tool access9 hits, unfilleted pocket corners

Deep pocket1 hit, 5.33:1 depth-to-width

StatusNeeds attention (0 critical)

Why it matters: a real end mill leaves its own radius behind at every internal corner. Ten features flagged, correctly none marked critical: a machinist would fillet them, not reject the part. Tool access has a real fillet fix on STEP models; deep pocket has no automatic fix today, so Buildable explains and recommends rather than pretending to resolve it.

Interactive example Casting: a mould that can't release its own core

A structural gearbox-style housing modelled with vertical walls and a fully enclosed cavity: no draft anywhere, and no core-print access for the sand or die to reach the inside.

Draft180 of 180 wall-candidate triangles at 0°

Wall uniformity6 hits, worst 24mm vs an 11.20mm cap

Undercuts1 feature: the whole cavity, sealed, no core access

Draft fixImproved, not resolved: 180 → 176 over two accepted operations; the third was refused

Why it matters: the draft fix ran twice and the kernel's third result came back an invalid solid, so Buildable discarded it rather than keep it. Two operations moved 180 flagged triangles to 176: real, and nowhere near a solved part. The cored cavity still needs a human's tapered-core redesign, and saying so is the point.

Interactive example SLA: trapped resin

A hollow electronics enclosure with a sealed interior cavity: uncured resin has nowhere to drain during printing, and a wide flat span bridges across the open bottom.

Trapped volume1 hit, fully sealed cavity

BridgingCritical, 63.5mm unsupported span

OverhangWarning, mostly an unavoidable flat base

Thin wall / stabilityClean

Why it matters: no automatic drain-hole fix exists yet, so Buildable explains the cavity it found and recommends adding a vent, rather than claiming to fix what it cannot.

Interactive example Sheet metal: a bend drawn without minimum radius

A folded bracket, two walls rising from adjacent edges of one base plate, the shared corner filleted at less than the material's own gauge and never relieved before the fold.

Bend radius1 hit, ~0.27mm inside radius on a 2mm gauge

Bend relief7 reads at the unrelieved corner and nearby edges

Flange length / holes near bendsEvaluated and clean: this bracket does present the open flat-pattern edge both checks measure against

StatusNeeds attention (0 critical)

Why it matters: a press brake needs a minimum bend radius and a relief cut where two folds meet, or the material cracks or tears as it forms. No automatic fix exists for this yet, so Buildable explains and recommends.
