Facetra is an AI-powered jewellery design workflow platform for Indian ateliers. It converts hand sketches into photorealistic renders, multi-view technical sheets, live-gold-rate Bill of Materials, and downloadable 3D meshes (GLB/STL/OBJ/FBX). Built for Jadau, Polki, Kundan, Meenakari, Temple and Rajwadi styles.

Does Facetra replace CAD software like Rhino or MatrixGold?

No. Facetra is a workflow layer that produces the reference material (renders, multi-view sheets, BOM, 3D mesh) a CAD operator uses. Your CAD bench continues to use Rhino, MatrixGold or JewelCAD to retopologize the mesh into a cast-ready model.

What jewellery styles does Facetra support?

Traditional Indian styles: Jadau, Polki, Kundan, Meenakari, Temple, Rajwadi. Modern styles: solitaire, halo, cluster, tennis, cocktail. The rendering vocabulary understands craft terms like chaton, bezel, prong, jaali, nakashi and meena work.

What 3D formats does Facetra export?

GLB (default), STL, OBJ, FBX, USDZ, GLTF and 3MF. Two quality tiers: Standard (25 credits, 4K PBR) and HD (35 credits, native 8K PBR).

How much does Facetra cost?

Credit-based pricing. Studio render 1 credit, multi-view sheet 4 credits, CAD-ready 1 credit, 3D mesh 25-35 credits. Credit packs: Starter ₹1,500 for 100 credits (₹15/credit), Studio ₹7,000 for 500 credits (₹14/credit), Atelier ₹15,600 for 1,300 credits (₹12/credit). New signups get 10 free credits.

Is my design confidential on Facetra?

Yes. Every design lives in a private per-user storage bucket. Nothing is public, nothing is shared with other users, nothing is used to train shared AI models.

Workflow Pillar

Jewellery Sketch to CAD — AI-Powered, Same Day

Paper sketch, tablet doodle, iPad reference — one image in, a full CAD kit out. Photoreal render, silhouette-locked multi-view, bare-metal CAD-ready view and a 3D mesh your CAD bench can retopologise for casting.

Start rendering — 10 free credits How it works

Every jewellery studio's biggest bottleneck sits between the sketch and the CAD file. A designer draws a piece in five minutes; a CAD operator then spends 6-14 hours in Rhino, MatrixGold or JewelCAD converting that sketch into a manufacturable file. Every client revision restarts the clock at ₹5,000-15,000 per CAD outsource.

Facetra collapses sketch-to-CAD to one afternoon. Upload the sketch — hand-drawn on paper, sketched on an iPad, or even a competitor render used as inspiration — and Facetra produces a photoreal client-ready render (40 seconds), a silhouette-locked multi-view sheet for the CAD bench (4 credits), a bare-metal CAD-ready reference (1 credit) and a production-ready 3D mesh in STL / GLB / OBJ / FBX / USDZ / 3MF (15-25 credits). Total: ~22 credits Standard ≈ ₹264 (or ~32 credits HD ≈ ₹384). Traditional route: ₹5,000-15,000 and 4-7 days.

What is AI sketch-to-CAD for jewellery?

AI sketch-to-CAD for jewellery is a multi-stage pipeline that (1) reads a 2D sketch or reference image, (2) generates a photoreal render with correct material and stone treatment, (3) generates silhouette-locked multi-view sheets that a CAD operator can model against without drift, (4) generates a bare-metal casting reference stripped of stones and enamel, and (5) generates a production-ready 3D mesh with correct wall thickness for lost-wax casting or DMLS 3D printing. Facetra is the only such tool with jewellery-native vocabulary (Kundan / Jadau / Polki / Diamond / Temple / Meenakari).

What Facetra's sketch-to-CAD pipeline delivers

Any input — paper sketch, iPad/Procreate export, reference photo, competitor render, mood board collage
Photoreal render in 40 seconds — client-approval quality with correct material and stone behaviour
Silhouette-locked multi-view sheet — 0° / 45° / 90° / 180° views the CAD bench can model against
Bare-metal CAD-ready view — the casting geometry stripped of stones, foil and enamel
Production-ready 3D mesh — STL / GLB / OBJ / FBX / USDZ / 3MF, wall-thickness aware for casting
Auto-Split component detection — decompose the piece into individually addressable parts (chaton / prong / jaali / meena / drop / chain)
Style-fluent — Kundan / Jadau / Polki / Diamond / Temple / Meenakari across the whole pipeline

The Facetra workflow (six steps, one afternoon)

Take a photo of your paper sketch (any angle, any lighting) or export your tablet drawing as PNG.
Upload to Facetra Studio. Optional: tag style (Kundan / Diamond / …) and metal (22kt / 18kt / …).
Facetra renders a photoreal preview in 40 seconds — send to client for a first look.
On approval, generate multi-view sheet (4 credits) + CAD-ready bare-metal (1 credit) + BOM (1 credit).
Generate 3D mesh — Standard (15 credits) for review, HD (25 credits) for direct-to-printer.
Hand the CAD kit to your CAD operator for retopology in Rhino / MatrixGold, or send the mesh directly to a 3D-printed wax.

Sample prompts to copy

Paste any of these prompts into Facetra Studio to see the style in action. Adjust weights (heavy / light), stone colours and motifs freely.

Prompt 1Paper sketch of a Kundan aad, seven panels, uncut Polki chatons, jaali shoulders — render as photoreal 22kt gold with green meenakari reverse and generate full CAD kit

Prompt 2iPad sketch of a modern halo ring, oval centre, cathedral setting — render as 18kt white gold with 1.5ct oval diamond and generate CAD kit with 3D mesh

Prompt 3Rough reference collage of temple vanki — sculpt Lakshmi iconography with high-relief nakashi, granulation border, uncut ruby chatons; generate multi-view + 3D mesh per component

How much does it cost?

Credit-based pricing. Studio render 1 credit per variant, multi-view sheet 4 credits, CAD-ready view 1 credit, 3D mesh 15 credits (Standard) or 25 credits (HD). Credit packs start at ₹1,500 (Starter, 100 credits, ₹15/cr) and go down to ₹12/credit on the Atelier pack (1,300 credits at ₹15,600). New signups get 10 free credits.

Frequently asked questions

Does the sketch need to be a clean drawing or can I upload a rough thumbnail?

Rough thumbnails work — Facetra's silhouette detection is trained on studio sketches that range from finished renders to napkin doodles. The cleaner the sketch, the more silhouette-faithful the render, but even a rough thumbnail produces usable output. For total precision, upload a reference photo of a similar piece as a second image.

Is the 3D mesh production-ready or a design reference?

It's design-reference geometry — manifold, wall-thickness-aware, symmetric — that a CAD operator retopologises in Rhino / MatrixGold before casting. Wall thicknesses default to 0.6-0.8mm for lost-wax and 1-2mm for DMLS. Any professional atelier runs a retopology pass before commercial cast, but the mesh is directly usable for 3D-printed wax samples and client-approval prototypes.

How much does a full sketch-to-CAD kit cost?

~22 credits Standard ≈ ₹264 (or ~32 credits HD ≈ ₹384) on the Atelier pack (₹15,600 for 1,300 credits at ₹12/credit). Covers render + multi-view + CAD-ready + BOM + 3D mesh. Traditional outsourced CAD from sketch: ₹5,000-15,000 per piece, 4-7 days turnaround.

Can I chain this into my existing Rhino / MatrixGold pipeline?

Yes. Facetra outputs STL / GLB / OBJ / FBX — every retopology-ready format Rhino and MatrixGold accept. The mesh imports as reference geometry; your CAD operator retopologises against Facetra's silhouette (which is silhouette-faithful to the sketch) and produces the final casting file.

What if I want to iterate — client asks for a change after the first render?

Free lasso-refinement of specific regions (change a stone, deepen a meena, resize a centrepiece) costs just 1 credit per iteration and preserves the CAD kit downstream. You never restart the pipeline from scratch.

Does this work for heritage silhouettes like Aad, Vanki, Oddiyanam?

Yes — heritage silhouettes are a primary use case. The engine is trained on Indian bridal vocabulary and handles Aad panels, Vanki inverted-V armbands, Oddiyanam waist belts, Bajubandh armlets, Hathphool hand ornaments, Maang Tikka and Nath through the full sketch → render → CAD pipeline.
