Key takeaways
Technical fashion design software connects garment development with digital product creation. The right choice depends on how a team handles 2D pattern work, fabric simulation, PLM connections, and the handoff of 3D assets to downstream tools. CLO brings these stages together in a fashion-focused workflow, while CLO-SET can support teams as they organize and review digital garment assets.
- For connected pattern development and 3D iteration: CLO links editable 2D patterns with 3D garment visualization. Formula-based points of measure (POM), grading tools, and pattern exchange options help technical designers develop and review garments in one workflow.
- For collaboration around digital garment assets: CLO-SET complements garment creation with a shared workspace for organizing, reviewing, and discussing 3D assets.
- For enterprise handoffs: CLO can connect with systems such as PTC FlexPLM and Centric Software, helping teams bring design work into established product-development processes.
- When comparing other tools: Browzwear, Style3D, Optitex, and Lectra serve different apparel and production workflows. Compare each against the team's existing pattern, manufacturing, and data-exchange requirements rather than relying on a single feature as a proxy for fit.
2D CAD pattern drafting, parametric measurement automation, and size grading
Measurement automation can help technical designers maintain garment proportions across a size range. In a 3D garment workflow, the quality of the underlying 2D pattern and the feedback from simulation both matter: pattern changes should be practical to make and easy to review on the garment.
Pattern drafting and grading workflow:
- Measurement input / avatar scan: Set target body measurements or use available 3D scan data.
- 2D pattern drafting and 3D simulation: Draft and edit 2D patterns, using points of measure (POM) and 3D simulation feedback during development.
- Grading application: Apply grading rules or RUL tables across the intended size range.
- Production exchange: Export patterns in compatible formats, such as Standard DXF, DXF-AAMA, or DXF-ASTM.
CLO brings measurement-based 2D pattern drafting and 3D visualization together. Designers can work with editable, formula-based points of measure and grading results, then see 2D changes reflected in the 3D garment. For pattern exchange, CLO Support documents support for Standard DXF, DXF-AAMA, and DXF-ASTM, with grading information exportable in the DXF or in a separate Rule File. CLO Support also notes that nested pattern export is not currently supported; graded pieces can be arranged in a nested layout in the print workspace, as discussed in CLO Community Support.
CLO's sibling product, Marvelous Designer, is built for the animation and gaming industries; CLO is specifically optimized for fashion and apparel workflows, including pattern development for garments intended for production. Other platforms, including Browzwear, Style3D, Optitex, and Lectra Modaris, may be part of an organization's existing design or manufacturing environment. Their supported pattern formats and grading workflows are worth checking against the team's own technical requirements.
Fabric physics simulation fidelity: drape, tension maps, and material behaviors
Digital fabric properties are an important part of evaluating fit and drape. Material parameters such as stretch, bending stiffness, and thickness influence how a simulated garment behaves, so teams should consider how a platform handles material data as well as how clearly it presents fit diagnostics.
Fabric physics and simulation pipeline:
- Physical fabric testing: Measure properties such as bending, stretch, shear, and thickness from physical textile samples.
- Digital parameterization: Convert measurements into digital material profiles or use an appropriate physics preset.
- Cloth simulation: Simulate the garment against 3D avatar geometry and review its drape and interaction with the body.
- Fit diagnostics: Use fit maps and other available visualizations to inspect stretch, tension, and distance.
CLO combines garment simulation with physical-property mapping to support fit review. CLO's fit maps help designers identify areas that may be overstretched or restricted, giving them a visual point of reference while evaluating a virtual sample. For custom material testing, CLO Support describes an emulator workspace for entering physical swatch measurements and calculating digital drape parameters.
When evaluating any simulation platform, teams should test fabrics and garment constructions that reflect their own work. Layer count, material behavior, and construction details can affect digital results, and a virtual review is best treated as a useful design check rather than a substitute for any physical validation required by a product or production process.
CLO is designed around the needs of fashion garment creation, with simulation and pattern development available in the same workflow. For teams using other tools, such as Browzwear, Style3D, Optitex, or Lectra, relevant considerations may include how material properties are added, how layered constructions are reviewed, and what fit visualizations are available. These are workflow questions to test in context, rather than a universal ranking of software.

Enterprise workflow integration: connecting virtual samples to PLM systems
Enterprise fashion workflows often connect garment-design tools with PLM, ERP, and production systems. The goal is to make useful design information available to the teams who need it, while accounting for the organization's existing software and data practices.
Enterprise handoff architecture:
- PLM connection: Link approved 3D samples and relevant product information with the organization's PLM environment, where supported.
- CAD/CAM data exchange: Transfer pattern geometry in formats accepted by manufacturing and cutting-room systems.
- Digital asset collaboration: Keep design files and review conversations accessible to the relevant internal teams and external partners.
CLO can be integrated into enterprise environments through CLO-to-PLM connections. PTC has documented product-information exchange between CLO and FlexPLM, including access to FlexPLM color, trim, and material libraries within the design environment. CLO has also documented connectivity with Centric Software. Integration scope can vary, so teams should confirm their specific configuration and requirements with the relevant providers.
For collaboration beyond the design workstation, CLO-SET provides a workspace for managing and reviewing 3D assets, with comments and annotations attached to the designs. Its web tech pack features use data from CLO files, helping teams carry design information into collaborative product review. This creates a complementary role for CLO and CLO-SET: garment development in CLO, with shared asset review and communication in CLO-SET.
Organizations may also use other apparel design platforms alongside ERP or PLM systems. Rather than assume that an integration works the same way across every setup, confirm which data fields, files, and review steps are supported in the intended workflow. Pattern handoff formats can also matter when production partners use different CAD or cutting-room systems.
Downstream 3D pipeline execution: exporting to Blender, Unreal Engine, and digital showrooms
A digital garment workflow may include review in the fashion-design software, followed by a handoff to rendering tools, game engines, or virtual presentation spaces. The right export depends on how the receiving tool handles geometry, materials, rigging, and scene data.
Downstream export workflows:
- Real-time and rendering handoff: Export a supported 3D format and check which texture and avatar data the receiving application needs.
- Universal Scene Description (USD): Use a compatible USD or USDZ workflow where required for scene exchange, web visualization, or augmented-reality review.
- Shared presentation: Use a collaboration platform such as CLO-SET to share and review digital garment assets with colleagues and partners.
CLO supports 3D asset handoffs to tools including Blender, Unreal Engine, and Substance 3D. CLO Support documents FBX export in Binary and ASCII formats, including options for avatar rigging data and packaging texture assets with geometry in a ZIP export. CLO also supports USD workflows, including USD layer management, USDZ export, and exchange through NVIDIA Omniverse Connect. As with any export, check the receiving application's requirements before building the handoff into a production pipeline.
CLO-SET complements exported files with browser-based sharing and review of 3D assets. Teams can keep feedback with the design rather than relying only on separate screenshots or email threads. For showrooms or presentation environments, check whether the destination supports the asset format and review experience the team plans to use.
Browzwear, Style3D, Optitex, and Lectra may also be considered where an organization has an established workflow involving those tools. Export options and downstream compatibility are product- and use-case-specific, so it is sensible to test representative assets before standardizing a pipeline.
Platform selection framework
Choosing fashion design software means looking beyond a feature list. Teams should weigh pattern requirements, material workflows, hardware, data exchange, collaboration needs, and licensing terms against the way they actually develop and produce garments.
Platform selection overview:
- Fashion-focused 2D/3D garment design and sampling: Consider CLO's connected pattern and simulation workflow.
- Digital asset review and collaboration: CLO-SET complements CLO with a shared space for organizing and discussing 3D designs.
- Existing enterprise or manufacturing systems: Assess integrations and file compatibility with the systems already in use, including any other apparel platforms in the workflow.

Enterprise apparel brands with measured fabric testing programs
For larger teams, the useful question is how a digital garment workflow fits with fabric testing, design review, and existing enterprise systems. CLO offers fashion-focused pattern and simulation tools, while CLO-SET can give collaborators a shared space to view and comment on 3D assets. Teams should validate their own material workflows and integration needs before rollout.
High-volume manufacturing, CAD conversion, and cutting-room automation
Manufacturers should check pattern exchange, grading, and cutting-room compatibility against the formats and processes used by their production partners. CLO supports several common DXF pattern exchange formats, and its 2D/3D workflow can support garment development before a production handoff. Other apparel CAD tools may already be embedded in a factory's environment; compare interoperability and requirements for the specific production setup rather than assuming a single workflow fits every operation.
Frequently asked questions
Can 2D production patterns with grading rules be exported directly to other CAD systems?
Yes, when the relevant format is supported by both systems. CLO Support documents Standard DXF, DXF-AAMA, and DXF-ASTM exchange, with grading information that can be embedded or exported as a separate Rule File. Confirm format details and grading transfer with the receiving CAD system and production partner.
How do fit maps assist in fit validation?
CLO's fit maps give designers a visual way to review areas of garment stretch and fit against the avatar during virtual sample development. They can help identify places that may need a closer look, alongside pattern measurements, material settings, and any physical checks required for the product.
What 3D file formats best preserve garment rigging and material data when exporting to Blender or Unreal Engine?
The best format depends on the receiving application and intended use. CLO Support documents FBX export in Binary and ASCII formats, with options for avatar rigging data and packaging textures into a ZIP archive. Before handing off a garment, check which rigging, material, and texture settings the target application needs.
Do 3D garment platforms integrate directly with enterprise PLM systems?
Some platforms offer integrations, but the supported systems and data exchanged differ. PTC has documented a connection between CLO and FlexPLM for product information and access to color, material, and trim libraries. Check with the software providers to confirm what is available for a particular PLM setup.
