A carved pediment and a monument: architectural decor for CNC

A carved door-surround pediment from a historic survey drawing and an entry monument with stone veneer. CNC-ready models, colour visuals with a human figure and mounting sheets in US units.

THE BRIEF

What had to be delivered

DWG-3131
BRIEF
Proofs · 2026

First piece: a door-surround pediment with a carved frieze, acanthus consoles and rosettes, from a historic photogrammetric drawing, with maximum detail for foam routing.

Second: an entry monument from a photo, with stone veneer, letters and a medallion. Three sheets for each: dimensions, a visual with a human figure, foundation or mounting.

ENGINEERING CONSTRAINT

What made it non-trivial

DWG-3132
CONSTRAINTS
4 ITEMS

Ornament once cut by hand had to become geometry a machine can route.

Carving as geometry. The scrolling frieze with a shell, acanthus consoles, rosettes, egg-and-dart and leaf mouldings on the raking cornice are separate meshes over an exact BRep architecture.

Dimensions from a photo. The monument is rebuilt from a photograph: scale comes from a perspective calibration on the logo ellipse, so the sheets say field verify.

406 stones. The monument veneer is made of individual stones in six colours, not a single texture.

Someone else's drawing standard. Sheets in inches, in production-proof format with colour swatches, French-cleat mounting and an ENGINEERING TBD box for the engineer's seal.

SOLUTION

How I solved it

DWG-3133
METHOD
5 STEPS

Architecture as exact BRep, carving as procedural meshes, sheets generated from the same geometry.

01

Pediment: eared architrave, frieze, consoles, entablature and a raking cornice at 22.5°

02

Carving: procedural frieze rinceau, acanthus consoles, rosettes, egg-and-dart and leaf-and-dart, trimmed at the ends

03

Full STEP: exact BRep plus carving as tessellated bodies, verified by import into Fusion

04

Monument 144 × 63.5 × 38″: base, piers, 66 × 37″ sign panel, 3/4″ and 1/2″ HDU letters, Ø10″ medallion

05

Sheets: exact scaled orthographic view, profile sections, CNC part breakdown, foundation and fixing

per piece

The pediment is routed from 2 lb/cf EPS, carved zones from 15 lb/cf HDU for sharper detail, polyurea hard coat, faux-wood finish. Wall mounting on French cleats, split into five parts P1…P5.

Monument: foam blocks with faux-stone veneer, HDU sign panel, metal letters, embedded posts in the foundation per sheet S-1.

RESULT
·

A historic ornament became a model the machine routes parts from, and the sheets show how to assemble and hang them.

Both pieces follow the fabricator's own standard, so the proofs can go to their client without rework.
