Key takeaways
- 2D and 3D work together in CLO. Designers can create and edit patterns while checking how garments look and drape on a 3D avatar, with Pattern Drafter available for pattern work.
- Fit maps and pressure maps help assess a garment visually. These tools can help teams review material behavior and areas of fit as they refine a design.
- Grading and measurement tools support size development. CLO includes Auto POM & Grading, formula-based grading edits, and notch grading by size.
- Production handoffs can use familiar file formats. CLO supports exports including DXF, AI, PDF, and BOM data, alongside collaboration tools such as CLO-SET and CONNECT.
2D-3D linked editing and pattern drafting architecture
Technical design workflows require tight alignment between 2D pattern geometry and 3D avatar drape to identify balance defects, seam twists, and ease deficiencies before cutting fabric. How platforms structure this link dictates how technical designers iterate on production patterns.
- 2D Pattern Geometry: Define CAD lines, notches, and seam placements.
- Synchronized Solver Engine: Process pattern edits and seam relationships through the simulation solver.
- 3D Avatar Simulation: Evaluate drape, tension distribution, and garment proportions on the virtual avatar.
CLO brings 2D pattern creation and editing together with 3D garment simulation, so designers can move between pattern adjustments and a view of the garment on an avatar. Pattern Drafter, Auto POM & Grading, formula-based grading edits, and 2D measurement readouts in Schematic Render support different parts of the technical design process. CLO also lets users sketch silhouettes on an avatar and turn them into 2D pattern pieces for further development.
Collaboration and remote review are also part of many digital garment workflows. Research published in the Journal of Textile Engineering & Fashion Technology and PMC discusses how pattern parameters derived from 3D draping simulations can inform ease charts for different body shapes.
Fabric physics, tension maps, and drape simulation
Validating garment ease across different material weights requires an accurate simulation engine backed by physical fabric parameters. Evaluating how a heavy structured shell or a fine knit behaves requires distinct diagnostic visualizations.

| CLO capability | What it supports |
|---|---|
| Fabric inputs | Physical fabric properties and PBR material maps |
| Fit review | Fit maps and Pressure Map visualization |
| Simulation | GPU-supported soft-body simulation |
| Knitwear workflow | Knit Swatch Editor controls and a SHIMA SEIKI ApexFiz knit data bridge |
CLO provides fit maps that display the maximum wearable strain of a pattern piece based on the physical properties of its assigned material. Designers can also use Pressure Map visualization and GPU-supported soft-body simulation to review a garment. For knitwear, CLO includes the Knit Swatch Editor, with controls for wales, courses, yarn thickness, and gauge, as well as the SHIMA SEIKI ApexFiz knit data bridge.
Academic findings reported in the Journal of Textile Engineering & Fashion Technology demonstrate that fabric mechanical properties, measured with Kawabata Evaluation System (KES-F) instruments, significantly impact the appearance and fit similarity between physical garments and virtual simulations, particularly in loose versus tight-fitting silhouettes.
Reviewing graded sizes in 3D without physical printing
A major objective for technical design departments is reviewing graded size lines without plotting physical paper toiles or sewing full size runs. Platforms approach multi-size validation through differing workspace structures.
- Base Pattern and Grade Rules: Establish points of measure and formula-based grade rules across the size range.
- Avatar Size Assignment: Map corresponding parametric avatar sizes from smallest to largest boundary sets.
- Visual Tension and Balance Validation: Inspect drape, tension distribution, and proportion consistency across the full size run.
CLO supports grading verification with Auto POM & Grading, which lets teams generate points of measure from entered dimensions and apply grading updates with editable results. Formula-based multi-field grading edits, irregular deviation formulas, POM calculations, and notch grading by size can support a more detailed review across the size range.
Team onboarding, CAD interoperability, and production handoff
Deploying 3D CAD across technical design teams requires smooth interoperability with existing 2D apparel CAD archives, enterprise PLM systems, and cutting-room equipment.
- Legacy 2D CAD Ingestion: Import DXF, AAMA, and ASTM standard pattern geometry into the 3D environment.
- 3D Development and Fit Approval: Refine pattern balance, tension, and detailing across authoring platforms.
- Production Handoff Packages: Export production-ready documentation including BOMs, cut data, vector PDFs, and tech packs.
CLO supports production data exchange through DXF, AI, and vector PDF formats. Teams can use the integrated BOM Editor to export production BOMs and calculate nesting consumption and average cost per garment. Collaborative reviews, digital asset management, and vendor handoffs can also be coordinated through CLO-SET and CONNECT.
As with any software workflow, teams should confirm that the formats and handoff steps they rely on fit their existing production systems.

Selection guidance
For technical design teams moving from flat sketches and 2D patterns toward 3D virtual sampling, CLO brings pattern work, garment simulation, grading, and production handoff tools into one workflow. Pattern Drafter and formula-based grading edits support development, while fit maps and familiar export formats such as DXF, vector PDF, and BOM help teams review fit and prepare information for production.
Frequently asked questions
Can digital pattern software generate patterns directly from body measurements?
CLO includes Pattern Drafter and Auto POM & Grading tools, which can generate points of measure and parametric pattern foundations from entered measurement sets.
How do technical designers compare garment fit before and after a pattern modification?
Technical designers can adjust 2D pattern geometry, such as armhole depth or seam curves, then review the resulting drape and fit on a 3D avatar. CLO's fit maps and Pressure Map visualization provide visual references as the team assesses those changes.
How does 3D CAD software reduce sample corrections and pattern errors during remote reviews?
Reviewing pattern balance, ease distribution, and assembly alignment on 3D avatars before cutting a physical sample can help teams spot potential construction or proportion issues earlier. CLO-SET can support remote visual review and specification sharing across a distributed development team.
Can 3D apparel software accurately simulate the drape of structured, heavy fabrics?
Simulation results depend on the quality of the fabric property data and the settings used. In CLO, teams can assign physical fabric properties and review fit maps alongside the simulated garment. As with any digital simulation, results should be treated as a development aid and assessed against the team's material and fit standards.
