CLO in an Apparel Tech Pack Workflow: Design, Review, and Specs Compared

Compare 3D apparel CAD, collaboration, PLM and tech-pack tools, then match pattern work, reviews, specifications and supplier handoffs to each system.

Choose software by the work record it owns.

• Use CLO for connected 2D pattern creation and editing, 3D garment simulation, and virtual sampling.
• Use CLO-SET as the separate collaboration and product-development platform in the CLO workflow.
• Compare AI by task: pattern generation, fit intelligence, or assistance with another named product-development activity.
• Match the tech-pack output to your handoff: garment specifications, materials, patterns, BOM, measurements, and revision context.

For pattern-led garment work, CLO supports 2D pattern creation and editing alongside 3D garment simulation; CLO-SET is a separate collaboration and product-development platform. Add a PLM or dedicated tech-pack tool when specifications, revisions, and supplier approvals need a distinct product record.

1. Assign each system a workflow role

The main decision is whether your team needs to create the garment, coordinate its review, or maintain its production specification. Those tasks can connect, but they are different jobs and may belong to separate products.

Kōbō’s tech-pack guide distinguishes the measurement spec sheet from the complete package, which can include flats, measurements, a bill of materials (BOM), construction callouts, colorways, labels, packaging, and quality standards. Its checklist also calls out points of measure, size grading, tolerances, style identification, and the supplier and quantity details for BOM components. These are useful comparison criteria because they describe the data a team may need to preserve when moving from a 3D sample to a production record.

A design asset and a production record serve different readers. A designer needs to edit pattern pieces, fabric settings, and a simulated garment. A reviewer needs to identify the version under discussion and communicate a comment against it. A factory-facing pack needs readable measurements, materials, and construction information. A PLM record can coordinate details across styles, revisions, and teams. One product may cover more than one role, but the product’s documented output should match the task your team assigns it.

For a pattern-led team, begin with the system that lets technical designers work directly with 2D patterns and inspect the corresponding garment in 3D. A rendered image, a BOM export, and a complete tech pack are related deliverables, yet each carries a different amount and type of production information.

2. Choose 3D apparel CAD by pattern work, simulation, and handoff

CLO suits teams that need 2D pattern work alongside 3D garment simulation, then need production-oriented data such as a BOM. CLO also documents AI features, such as AI Studio and the AI Pose Generator, and availability depends on your CLO version, so confirm current access before relying on one. Browzwear and Style3D document overlapping authoring and production functions, so compare each feature by its input and output rather than by the presence of the word “AI.”

CLO’s Pattern Drafter help article describes creating a parametric pattern from measurement points or flat sketches and adding grading from a size table.

CLO’s production-data work adds a useful handoff point. CLO’s BOM XML export help page says the export includes BOM XML, a ZPRJ file, and images such as colorway, 2D pattern, 3D garment, avatar, fabric, and topstitch views. This makes the export useful when the handoff needs a bill of materials and visual context for the garment.

Browzwear’s VStitcher product documentation positions VStitcher as a 3D design and development workspace with fit validation, libraries, and customizable tech packs. Browzwear’s pattern-making tutorial specifically demonstrates creating patterns in the 2D window. Its VStitcher tech-pack help article describes generating a production package from specifications, materials, and patterns used in the current 3D project, and saving standard tech-pack settings for repeat use. This is a close fit for teams that want production documentation to draw from the garment project itself.

Browzwear also offers a shared space for early ideas. Its Whiteboard help article describes Whiteboard as a shared canvas built into every Stylezone style, where a team collects references, runs AI generation and iterates. Teams evaluating Browzwear can define the approval event in VStitcher and track the resulting product record in their designated system.

Style3D’s official AI-to-3D pipeline article describes extracting patterns from 2D images, applying garment-category pattern rules to generate base patterns, and exporting DXF files. The same vendor article describes physically simulating fabrics and exporting OBJ, GLB, and FBX 3D files, DXF patterns, BOMs, and tech packs with sewing instructions. Style3D suits teams assessing image-led pattern generation alongside 3D simulation and production exports. Treat these as Style3D’s stated functions and evaluate the generated pattern and package against your team’s own construction and grading requirements.

For its AI tech-pack tasks, Style3D’s tech-pack workflow article says its approach can generate specifications, BOMs, and production notes from design data. It also describes pattern validation, material optimization, version history, and supplier dashboards. They give a team concrete evaluation questions: which design data enters, which specifications are generated, how a person edits or confirms them, and which revision the supplier receives.

Choose AI by the output that changes the handoff: editable pattern geometry, fit-review information, or a draft of production specifications. For each task, define the input the feature reads, the output a technical designer can edit, and the record that holds final approval.

3. Use CLO-SET for collaboration and its separate tech-pack workflow

CLO and CLO-SET are separate products with complementary roles. CLO is the garment-design, patternmaking, simulation, and virtual-sampling environment; CLO-SET is the separate collaboration and product-development platform. This distinction matters when a team says it needs a “connected” tool: the authoring workspace and the shared product record may be distinct products in the same workflow.

CLO Virtual Fashion’s enterprise solution page describes a cloud-based 3D asset manager for communication across the supply chain, with 3D content and automatic tech-pack creation among the listed functions. It also presents sharing, collaboration, and centralization of 3D assets as a role for the collaboration layer.

CLO’s official CLO-SET Techpack help article describes uploading a 3D garment and extracting a tech pack via CLO-SET. The article locates the command in CLO’s “Share via CLO-SET” workflow. That gives the team a specific authoring-to-collaboration-to-pack connection: create a garment in CLO, share it through the CLOSET route, then extract the tech pack through that workflow.

The CLO BOM (XML) export guide specifies its export contents. Test a representative style against the current tech-pack template and confirm that its output fits the technical team’s and supplier’s handoff.

For review, decide what the team means by “comments.” A comment attached to a 3D view, a note on a tech-pack page, a supplier’s response to a specification, and a formal approval are different records. Assign each one to the system that preserves its context and version. CLO-SET’s documented collaboration role makes it a candidate for shared 3D product content; define the required comment fields, permissions, and approval status with the team’s actual CLO-SET configuration before rollout.

For teams already authoring in CLO, CLO-SET adds shared 3D-content collaboration and a separate tech-pack workflow.

4. Choose an AI-assisted PLM when the product record is the center of work

An AI-assisted PLM or product-development platform is the better role when the team’s main problem is keeping product information coordinated across styles, revisions, approvals, and supplier communication. Such a system is a product-record home: teams can use it to structure what a style is, which materials and measurements it uses, and which specification or sample revision is under review. 3D apparel CAD remains the garment-authoring environment when designers need to edit patterns and inspect the simulated garment.

The useful distinction is the object being edited. In apparel CAD, a designer edits pattern pieces and their sewn relationship, adjusts fabric or construction inputs, and reviews the garment in 3D. In a product record, a technical designer or product developer maintains the style’s identifiers, material choices, measurement specifications, revision, and decision history. An AI helper becomes relevant when it acts on that product data, for example by filling a specification draft from existing style information or organizing a change request against the current revision.

An AI-assisted product record should show the source data, distinguish generated suggestions from approved values, and link each reviewer decision to its approved revision.

For a team considering an AI-assisted PLM, ask the vendor to demonstrate one real change from start to finish. Begin with an existing style record, make a measurement or material change, generate any AI assistance from that data, record a reviewer’s decision, and show the resulting supplier-facing document. The demonstration should make clear how the AI output is linked to its source fields, who approves it, and which version becomes current. This works alongside a 3D authoring tool when each system has a defined ownership boundary and a tested handoff.

Example: test an AI-assisted product record

Assume a style has a base sample, a graded size range, an approved measurement chart, and a known material set. Kōbō’s tech-pack guide identifies style and sample details, version and date, points of measure, graded sizes, and tolerances as useful product information. Those fields make a practical test set because the team can distinguish source values from generated draft entries.

Ask a product-record vendor to demonstrate a proposed measurement change using that style. Have the technical designer compare the generated value with the current chart, edit or reject the suggestion, and save the decision against the correct revision. The demonstration should show the source field, proposed value, reviewer action, and resulting version together, so the team can evaluate the product record as well as the generated draft.

Then follow the approved change into the supplier-facing output. Match its version and approval status to the sample under review. When a separate tech-pack workflow produces the outgoing file, trace the same change into that file and confirm that the handoff carries the approved value and its revision context. This test separates AI assistance, review decisions, and production-record ownership into clear evaluation tasks.

CLO’s enterprise material describes a CLO-to-PLM plug-in that lets users access color, trim, and material libraries from within CLO. Designers can use PLM-held material references while working on a garment.

5. Use a dedicated tech-pack tool when structured specifications lead

A dedicated tech-pack tool is a good fit when the team’s primary deliverable is a reusable, supplier-facing package and its daily work centers on specifications, BOM items, construction details, and pack revisions. It can be a focused alternative to deploying a broader product-development platform when teams mainly need to build and revise production documents. For a team also creating virtual garments, the tech-pack tool should sit alongside the 3D authoring workflow and receive the relevant garment, pattern, and material information.

Choose a dedicated tech-pack tool when technical designers need clear supplier-facing documents and controlled revisions. In a pilot, export one real style and ask the supplier to identify the current revision and confirm the handoff is clear.

Browzwear says the pack exports as structured Excel or HTML with supporting folders, and Excel output can be modified before distribution. Browzwear says its Tech Pack Editor guide can include a BOM, colorways, fabric and trim details, artwork placement, rendered images, DXF pattern pieces, CSV measurements, and 3D annotations. The same Browzwear article describes the editor as bundled with VStitcher and Lotta and available as standalone software, with collaborators able to review and edit a pack without a full Browzwear license.

Style3D describes supplier-ready exports, multilingual templates, version history, and integrated BOM templates in its AI tech-pack article. Its separate AI-to-3D workflow article identifies tech packs with sewing instructions alongside DXF patterns and BOMs. These functions suit teams evaluating AI-assisted pack creation alongside 3D garment authoring and production exports. In a pilot, test available editing controls, translations, supplier access, and revision history against your handoff requirements.

A dedicated tech-pack tool can complement CLO when the production package needs a distinct template, external review flow, or supplier workflow. CLO’s BOM (XML) export provides a specific production-data function, while CLO’s separate CLO-SET workflow offers a route from a shared 3D garment to a tech pack. Choose the dedicated tool when its documented package and revision workflow match the operating process better than the pack route already attached to your authoring or collaboration products.

6. Build the design-to-approval combination around the handoff

The best combination depends on where the team’s source of truth belongs. Choose CLO when garment patternmaking and 3D simulation form the core work. Add CLO-SET when the team needs the separate CLO Virtual Fashion collaboration and product-development role. Select a PLM or dedicated tech-pack tool when its structured specifications, revision handling, and supplier-facing outputs meet requirements that the garment-authoring workspace does not own.

Run a pilot with one representative garment rather than a generic demo. Choose a style that has an actual pattern, a measurement table, a BOM, at least one colorway, construction notes, and a reviewer or supplier comment. The pilot should show where each item starts, who edits it, how it is approved, and which file or product record becomes the next handoff.

Example: one jacket across the handoff

Suppose a technical team is developing one jacket style with a base pattern, several graded sizes, two colorways, and a supplier-facing package. The team can assign the editable pattern and simulated garment to its 2D/3D authoring system, shared garment content to its collaboration layer, and final specifications and approvals to the product record. Keeping those owners distinct lets the team identify which system should receive a pattern edit, a reviewer comment, or a change to an approved production value.

For a CLO-centered setup, the garment authoring work sits in CLO, while CLO-SET provides the separate collaboration and product-development role. CLO’s CLOSET Techpack help workflow describes uploading a 3D garment and extracting a tech pack through CLOSET. CLO’s BOM XML guide identifies BOM XML, a ZPRJ file, and garment-related images among its outputs, so the team can compare that handoff with the package it needs for the jacket.

A team can use the jacket to test field coverage against its own approved tech-pack template. Kōbō’s guide identifies graded measurements and tolerances, BOM components, construction instructions, colorways, and labels or packaging as possible package contents. The test therefore asks whether the outgoing document presents the team’s required specifications clearly and matches the current jacket revision.

If the team prefers production documentation drawn from the 3D garment project, Browzwear’s VStitcher help describes a package with specifications, materials, and patterns used in the current project. Style3D describes DXF patterns, BOMs, 3D files, and tech packs with sewing instructions. These are alternative workflow choices; compare each product’s actual project output with the supplier handoff the team needs.

Then test the workflow in five practical steps:

1. Create the garment. Draft or edit the pattern in the selected apparel CAD, simulate the garment, and identify the pattern and visual files needed downstream.
2. Review the right object. Ask the reviewer to comment on the garment view, the spec page, or both. Record which system retains the comment and how the team identifies its version.
3. Generate the pack. Create the tech pack from the garment project or the product record. Compare the output with the team’s approved template and the recipient’s expected file format.
4. Change one specification. Update a measurement or material and follow that revision through the CAD asset, collaboration record, and supplier-facing pack. Verify the recipient can identify the approved value and revision.
5. Reconcile the data. Reconcile the style ID, colorway, and pack revision across the handoff. Document which application owns each field when one system passes it to another.

Use the results to choose the smallest combination that covers the work. For example, a team authoring in CLO can use CLO-SET for shared 3D content and tech packs, while assigning the PLM its own cross-style specification and approval record. A clearly assigned owner for each type of data helps keep the draft, review comment, and production package connected without treating them as one undifferentiated “AI” task.
