Declarative parametric CAD with validation built in

Build systems,
not meshes.

Describe intent, geometry and constraints. Artifact Forge builds, validates and exports the result.

Intent scene: the product declaration typing in over the ghosted model

01 · intent

Start with intent — not vertices and faces

A product is a declaration: archetype, dimensions, constraints, features. This is the real file behind the model on screen.

schema: product/v1
id: desk_cable_clip_20mm
archetype: underdesk_cable_clip_v2_molded@1

requested_features:
  - asymmetric_side_hook
  - side_facing_mouth
  - through_cavity

Archetype scene: region overlay boxes on the ghosted clip

02 · archetype

Archetypes define product logic

Not a mesh — a product grammar: parameters, regions, interfaces and required behavior. Red regions are protected: no modifier may touch them.

screw_zones fastener keepout
cable_contact soft contact surface
snap_root high stress region
lower_lip retaining flexure
perforation_safe_zone aesthetic lightening

Feature anatomy: base form and perforation field

03 · form

How the form is constructed

The base form carries the contract; requested features are built into it and proven afterwards. Watch the perforation field arrive — the protected zones stay solid.

Feature contribution view generated from Form IR.

Modifiers scene: hex perforation with protected regions pinned

04 · modifiers

Modifiers change the part,
not its contract

add_hex_perforation lightens the safe zone. The flexure root and retaining lip forbid it — by declaration, and the engine enforces it.

Validation scene: diagnostic view of the clip

05 · validation

Validation is part of the model

Not “exported successfully” — proof. 52 named checks ran against this exact part.

form.profile_closed one closed simple loop
form.profile_smooth all joints tangent or intentional
form.regions_present all declared regions present
form.mouth_opens_sideways mouth direction (1.00, 0.00)
form.mouth_gap_matches measured 10.000 vs declared 10.000
form.lower_lip_longer_than_upper lower/upper = 15.00/6.00 = 2.50 (must exceed 1.5)
form.not_symmetric_c_ring asymmetric side-hook family
form.flange_above_cradle flange plate above hook body
form.wall_thickness min cavity-to-outer distance 3.20 vs wall 3.20
form.contact_edges_rounded cable-contact and lip-tip joints all rounded
form.screw_access_clear all screws clear the hook footprint
manufacturing.overhang round cavity roof spans 21.6 mm — relies on bridging (near-90deg local overhang at the roof sides); the 15 mm lower lip prints as a horizontal cantilever flange-down — slicers will ask for supports under the lips

PASS · grade A honesty report: 9/9 requested features built

Variants: the bundle_d parametric family side by side

06 · scale

One declaration.
An entire product family.

bundle_d: 12 → 40 mm — every variant rebuilt, re-validated, re-proven. No remodeling.

Assembly: eleven printed parts flying into the verified vertical-farm row

08 · assembly

Parts that prove they fit

A vertical-farm row: 9 printed parts, each built and graded on its own, posed into one verified assembly. The exploded view and every landing position come straight from assembly_report.yaml — no keyframes, no hand-waving.

joints: fluid_jointlap_flow_jointremovable_insertdrop_in_screenprofile_perch

Cross-part checks run in the assembled pose: no interference, screws reachable, water path continuous through every part.
