# Draft Studio

> Turn 2D jewelry designs into manufacturing-ready 3D CAD models — textured meshes with dimensions and weight estimates, exported in GLB, FBX, OBJ, and USDZ.

Turn 2D jewelry designs into manufacturing-ready 3D CAD models. Draft Studio converts images into detailed, textured meshes with CAD dimensions and weight estimates, in standard export formats.

## Overview

* Image-to-3D conversion using multiple AI providers
* Quality tiers for previews through production
* CAD dimensions and metal weight estimates
* Stoneless mode for metal-only models
* Exports in GLB, FBX, OBJ, and USDZ

## Accessing Draft Studio

Open **Draft Studio** from the dashboard sidebar, or from the Gallery select a design and click **Generate 3D Model**.

## How it works

### 1. Upload your design

Use AI-generated designs, photos of existing pieces, or rendered concepts. Clear, well-lit images with clean backgrounds at high resolution (1024px+) work best. Multiple angles help.

### 2. AI analysis

AI analyzes your design with Qwen 2.5 VL 72B to identify the jewelry type, gemstones, settings, and metal components, then plans the 3D reconstruction.

### 3. Choose a generation mode

* **Full Design** — complete model with all gemstones and settings. Best for visualization and prototyping.
* **Stoneless / Mounting** — metal structure only, with gemstones removed. Ideal for CAD manufacturing, so jewelers can set stones manually.

### 4. Select a quality tier

* **Standard** — 100,000 polygons, 4K textures. Fast; good for previews and concepts.
* **High** — 150,000 polygons with mesh refinement. Suitable for most manufacturing.
* **Production** — 200,000 polygons, maximum detail. Best for final production files.

### 5. Generate and download

Get your 3D model with export options, computed dimensions, and weight estimates, ready for jewelers.

## Generation providers

* **Trellis (Fast)** — fastest generation and lowest credit cost. Best for quick previews.
* **Meshy v6 (Recommended)** — best quality/speed balance with accurate textures.
* **Meshy v5 Multi-View** — uses Zero123++ for multi-view synthesis. Highest accuracy for complex, intricate pieces.

## CAD dimensions and weight

Draft Studio computes:

* **Bounding box:** width, height, and depth, in millimeters.
* **Volume and surface area:** used for material calculations.
* **Metal weight estimates** by alloy, using typical casting density:
  * 14K and 18K gold (yellow, white, or rose)
  * 22K gold (traditional yellow)
  * Platinum 950
  * Sterling silver 925

## Your measurements

Provide real specifications for accurate scaling:

* **Ring:** size (US, UK, or EU) and band width (mm)
* **Chain / necklace:** length (inches or cm) and width (mm)
* **Center stone:** carat weight

## Export formats

* **GLB (recommended)** — binary glTF with embedded textures. Compact, widely compatible, best for sharing and web viewing.
* **FBX** — Autodesk interchange format. Strong CAD support, animation-ready.
* **OBJ** — universal format with separate texture files (MTL). Widest legacy compatibility.
* **USDZ** — Apple's AR format. View in AR on iOS; great for client presentations.

## Credit usage

Costs vary by quality tier and provider:

| Quality Tier   | Polygons | Approx. Credits | Best For               |
| -------------- | -------- | --------------- | ---------------------- |
| **Standard**   | 100K     | 15-25 credits   | Previews, concepts     |
| **High**       | 150K     | 30-50 credits   | Most manufacturing     |
| **Production** | 200K     | 50-80 credits   | Final production files |

Trellis costs the least, Meshy v5 Multi-View the most. Credit costs are shown before generation.

## Tips for best results

* **Image quality:** high resolution (2048px+), sharp, well lit, no blur or noise.
* **Multiple angles:** front, side, top, and angled views improve accuracy.
* **Clean backgrounds:** white or neutral, isolated piece, consistent lighting.
* **Accurate measurements:** provide real ring sizes, stone carats, band widths, and chain lengths.

## Troubleshooting

* **Model doesn't match design:** use higher-quality source images, a higher tier, or a different provider, and ensure a clean background.
* **Details missing:** increase to the Production tier, try Meshy v5 Multi-View, or upload higher-resolution images and multiple angles.
* **Weight looks off:** verify dimensions and metal type; estimates are approximate and assume typical construction.
* **Export won't open:** try another format (GLB has the widest support) or update your 3D software.
