Key Takeaway
- CLO pairs 2D pattern drafting and editing directly with 3D garment simulation so pattern updates automatically sync across both windows.
- Four diagnostic fit views and an accurate fabric simulation mode help teams inspect garment tension, pressure, and stretch before cutting physical samples.
- Support for rendering, USD pipelines, rigging optimization, and standard 3D exchange formats connects apparel review to external 3D scenes.
CLO brings 2D pattern work and 3D garment simulation together, so a flat sketch or an early 2D block can move into a pre-sample review in one place. Fit Maps, pressure views, and material controls let teams review a garment as the design develops.
Automatic 2D-to-3D Pattern Sync and Sketch Inputs
CLO synchronizes edits made in the 2D pattern window with the 3D window. If you make an edit while simulation is running, simulation stops; run it again to recalculate the drape and inspect the change.
For teams starting from early concepts rather than existing CAD blocks, two features generate initial pattern pieces:
- Sketch on Avatar lets designers draw garment lines directly on a 3D avatar and convert those lines into 2D patterns.
- AI Pattern Drafter can draft a pattern from a sketch or a garment or pattern image. Its text prompts generate an image within the tool before pattern drafting, so designers should review the resulting pattern and simulate it as part of their workflow.
Four Diagnostic Maps and Fabric Simulation Modes
Once a garment is assembled in the 3D window, CLO’s four Fit Maps help teams inspect the simulated result: Strain Map shows stretch caused by external forces as a percentage; Stress Map shows force per unit area of the fabric; Fit Map highlights tightness, including areas marked as not wearable; and Pressure Map shows pressure exerted by the garment onto the avatar.
You can toggle the Strain Map between Global Mode, which applies an identical scale across all fabrics, and Fabric Mode, which applies wearable stretch limits calculated from the fabric's physical properties or adjusted manually.
CLO’s Fitting (Accurate Fabric) simulation mode produces a more defined garment simulation and represents fabric stretch more realistically. For teams adopting 3D sampling, these visual checks support design review but don’t guarantee physical fit or wearer comfort; results depend on the fabric inputs and how the garment is tested. CLO’s own checklist starts with applying the fabric you’ll use on the real garment and simulating again after each design or fabric change.
USD Pipelines, Rig Optimization, and 3D File Handoff
For rendering or handoff to downstream 3D pipelines, CLO supports visualization and interoperability workflows that include rendering, USD/Omniverse, VRM, and common 3D exchange formats:
- CLO’s FBX import brings in camera data, and CLO supports OBJ and glTF/GLB import and export, including geometry and material information.
- CLO has a USD Layer window and can exchange USD data through Omniverse Connect.
Check current format and plug-in support for your pipeline before setting up an export routine.
How CLO Compares on Pattern, Fit, and Export Workflows
CLO, Browzwear VStitcher, and Style3D Studio support distinct pattern-to-3D workflows, diagnostic fit views, and 3D export formats.
| Software | 2D Pattern & 3D Simulation Workflow | Simulated Fit & Diagnostic Views | Rendering & 3D Interoperability |
|---|---|---|---|
| CLO | 2D pattern creation and editing alongside 3D garment simulation; 2D edits auto-sync with the 3D window; Pattern Drafter and Sketch on Avatar for starting patterns; DXF-AAMA/ASTM import and export | 4 maps (Strain Map in Global or Fabric Mode, Stress Map, Fit Map, Pressure Map), pressure views, material controls, and the Fitting (Accurate Fabric) simulation mode | Rendering, VRM, EveryWear FBX rig workflows, a USD Layer window with USD data exchange through Omniverse Connect, FBX import with camera data, and OBJ and glTF/GLB import and export |
| Browzwear VStitcher | Imports DXF files and runs garment simulation | Tension map (color-coded by fabric physics) and Pressure map (indicating pressure around shoulders and bust) | Creates a render after simulation finishes; exports Autodesk FBX, Browzwear PBR FBX, and USD files (from Version 2024.2) |
| Style3D Studio | 2D window for pattern shape and sewing-line editing; 3D window for avatar simulation | Body pressure, garment stress, garment deformation, thermal insulation analysis, and clothing section during virtual fitting | 3D window rendering; lists OBJ, GLB, and FBX as export formats |
Teams can check strain limits in Fabric Mode, then save a garment as FBX through EveryWear or work with USD layers in CLO. EveryWear is aimed at taking garments into gaming, metaverse, and entertainment pipelines.
FAQ
Can 3D fashion software help reduce sample corrections from pattern errors?
CLO’s automatic synchronization lets designers update a 2D pattern and re-simulate the garment in the 3D window. Fit Maps, pressure views, and material controls give teams useful checks during iteration, helping them spot areas to revisit before cutting a physical sample.
Which CAD tool helps with accurate garment visualization before sampling?
CLO’s Fitting (Accurate Fabric) mode produces a more defined simulation and represents fabric stretch more realistically, giving teams another way to review shape and drape against their material settings.
What 3D export options are available for advanced users who need clean exports?
CLO supports OBJ import and export, camera exchange with FBX and glTF/GLB files, and USD/Omniverse workflows. Confirm the current options your pipeline needs, then use them to build a repeatable handoff process.
