Preparations

• Style3D Studio installed (V8.0 or newer recommended)
• Account logged in; RAM ≥ 8GB (≥1GB free memory required for simulation)
• Prepare a DXF pattern file (generated from ET, Richpeace, Lectra, Gerber or other CAD software)

Interface Overview

• Left 2D Window — Displays pattern pieces for shape and sewing line editing
• Right 3D Window — Shows garments fitted on avatar for simulation and rendering
• Top Toolbar — File, Start (editing tools), Assets, etc.

Step 1: Create a New Project

1. Click top menu【File】▶【New】

2. Choose whether to save the existing project in the pop-up prompt

3. After creation, the avatar appears in the 3D window and the 2D window stays empty

Step 2: Import DXF Pattern Pieces

1. Top menu【File】▶【Import】▶【Import DXF File】(Or drag and drop DXF directly into the 2D window)
2. Confirm settings in import popup: Unit (mm/inch), import pattern seam allowance, reverse grainline, etc.
3. Click【OK】, pattern pieces will appear in the 2D window

• Distorted pattern outline → Check if spline curves are used in CAD; convert curves to polylines before export
• Extra seam allowance on patterns → Uncheck "Keep Seam Allowance" in import options or adjust manually in pattern properties
• Missing pattern segments → Some layers in DXF are unrecognized; check layer naming and closed patterns in CAD

Step 3: Sewing (Sew & Arrange)

3.1 Arrange Patterns onto Avatar

1. Enable【Show Arrangement Points】in the 3D window (blue dots appear around avatar)
2. Select pattern in 2D window → Click the corresponding arrangement point in 3D window
3. Front panel → Chest point; Back panel → Back point; Sleeve panel → Arm point
4. Repeat until all patterns are arranged

3.2 Create Sewing Lines

1. Click the start point then the end point of the first edge in the 2D window (watch arrow direction; it indicates sewing sequence)
2. Click the start and the end points of the second edge to be stitched (hold Shift to select multiple segments). The two edges will be linked as one sewing pair.
3. Repeat until all required edges are connected

Step 4: Simulation

1. Ensure all patterns are placed around avatar (no overlap or penetration)
2. Click【Simulate】button on top of 3D window (Hotkey: Spacebar)
3. Watch garment conform to avatar; click【Simulate】again to stop once stable

Simulation Tuning

• Set Particle Spacing to 15–20mm for first simulation to quickly preview overall shape
• Once the silhouette is acceptable, reduce to 5–10mm and enable【Precise Simulation】to generate realistic wrinkles
• For mesh penetration: pause simulation → drag penetrated pattern outward manually → restart simulation
• Prompt "Simulation terminated / illegal memory access" → Usually insufficient VRAM; close other applications and retry

Step 5: Save & Export

5.1 Save Project

1. 【File】▶【Save Project】(Ctrl/Cmd + S), file extension .sproj
2. A preview thumbnail is generated automatically on first save. The system captures the current 3D viewport image as preview and saves it together with the .sproj file. The thumbnail helps quickly identify projects in file browser or Resource Library.

5.2 Export 3D Model

• Select format based on downstream usage:
• OBJ — Universal 3D format for post-rendering in C4D / Blender / 3ds Max
• FBX — With skeleton and animation for game engines (Unity / Unreal Engine)
• GLB / GLTF — Preferred for web and mobile preview, small file size and fast loading
• U3D / PDF — For client review and design communication

5.3 Export 2D Technical Documentation

• 【File】▶【Export】▶【Export DXF】— Output revised paper patterns
• 【Tools】▶【2D Pattern Snapshot】▶【Export PDF/PSD/PNG, etc.】— 2D snapshot with dimension markings and sewing lines
