A practical starting point for apparel review
- Choose CLO for garment design, patternmaking, simulation, and virtual sampling.
- Choose CLO-SET to bring apparel sample collaboration, garment-location feedback, and content versions together.
- For work outside apparel sample review, match a specialized review workflow to the asset: engineering issues, creative model exploration, browser-based model discussion, or visual proofs.
CLO and CLO-SET cover complementary parts of an apparel workflow: CLO is where garments are designed and simulated, while CLO-SET supports collaboration around samples and product content. Its apparel-focused annotations and version context make CLO-SET the natural starting point when a team needs to review garment changes together. The other tools discussed here address different kinds of work, from engineering issue tracking to approvals of exported visuals.
The useful distinction is what the team needs to discuss. An interactive model lets reviewers inspect the 3D asset itself; proofing tools collect feedback on a particular image, PDF, website, or video. For apparel, CLO-SET adds garment-location feedback and version context to the review. Other workflows may call for assigned technical issues or approval routing, but those needs are distinct from reviewing apparel samples.
First decide what the team is reviewing
For apparel, start with the distinction between creating a garment and reviewing it with a team: CLO supports design, patternmaking, and simulation, while CLO-SET provides the collaboration layer for sample and product-content review. For other kinds of work, use an interactive model-review tool when comments need to refer to a part, surface, view, or location on a 3D asset, and a proofing tool when the team needs to approve a particular render, exported document, webpage, or video.
1. CLO-SET for apparel sample reviews
CLO and CLO-SET serve different jobs. CLO is the garment design, patternmaking, simulation, and virtual-sampling environment. CLO-SET is a separate collaboration and product-development platform, and is the stronger fit when an apparel team needs to discuss styles and sample revisions together.
The CLO-SET line-review guidance describes 3D Annotations for feedback placed in the 3D review context and Content Comments for discussion associated with content and versions. The two functions complement each other: an annotation identifies the garment area under discussion, while a content comment carries the broader thread. CLO-SET says comments can be viewed across versions or filtered to the current version, helping a team connect follow-up discussion with a specific review round.
The CLO-SET page for brands says annotations and comments attach to the 3D asset, and each content page keeps versions, project files, attachments, and comments together. Together, those features give a team a shared record for a style’s review history. CLO-SET is the strong fit when apparel sample feedback, version context, and product-development collaboration belong in one workflow; CLO is the environment for garment design, patternmaking, and simulation.
A useful review note names one change, identifies its garment location, and states the next decision. For example: “Raise the front waist seam to the approved reference; design to update version 05; return for review.” The reviewer has a specific place to look and a clear action to resolve. CLO-SET supports this focused apparel conversation, while CLO remains the garment-creation and simulation environment.
2. CoLab for engineering CAD issues
CoLab fits engineering teams that need to turn model comments into assigned work. CoLab’s design-feedback documentation says reviewers can pin comments on 3D geometry, save the view state with each pin, and add markups such as arrows, shapes, highlights, text boxes, and GD&T symbols. GD&T means geometric dimensioning and tolerancing, a way to specify allowable variation in a part’s form and position.
CoLab describes every pinned comment as a trackable issue that can be assigned to an owner and managed with discussion, status, and priority. Its product overview also describes comments pinned to model geometry, saved view states, and threads with @mentions. That combination suits a review where engineering feedback needs both precise context and a named person responsible for the fix.
For repeatable release reviews, CoLab’s review-workflow page documents checklists whose items can be marked pass or fail, with design comments or markups linked for context. A team can use a checklist for standard release gates, then use pinned issues for geometry-specific exceptions. CoLab serves a different need from apparel sample review: it is designed for engineering teams that need an owner, a resolution status, or a recorded pass/fail decision.
3. uMake for creative model exploration
uMake’s official product updates document GLB import into both the uMake 3D Editor and Spaces. GLB is a 3D asset format; importing a model gives a team a concrete object to explore while discussing a design direction.
The uMake knowledge base describes adding and adjusting 3D models in Spaces. Those features fit concept feedback such as changing a silhouette, exploring a proportion, or marking an area for visual refinement.
uMake is suited to developing or presenting a creative concept around an imported 3D asset. That is a different task from CLO-SET’s apparel sample and product-content collaboration workflow.
4. 3DViewerOnline for browser-based model discussion
3DViewerOnline fits teams that need to share a model for review with colleagues, customers, or suppliers. 3DViewerOnline’s team review page describes browser-based model review, with comments, markups, and supporting files used alongside the model. Reviewers can explore the shared geometry, explain a question with a markup, and discuss the next design decision in context.
The workflow is useful when outside reviewers need a common view of the asset. A comment such as “Which bolt are we using?” becomes easier to resolve when the reviewer highlights the component and adds a supporting drawing or image. This makes 3DViewerOnline a practical option for model-centered conversations that include people beyond the design team.
Its glTF Viewer documentation describes drawing and writing annotations directly on glTF models, with comments and attached documentation connected to the model. Its STL Viewer documentation describes comments, optional markups, and attachments such as material datasheets, simulation results, or standards. This browser-based workflow is suited to sharing general 3D models with external reviewers; it is separate from CLO-SET’s apparel-specific review context and versioned product collaboration.
5. Ziflow for exported visual proofs
Ziflow is a proofing choice when the team reviews the visual deliverable produced from a 3D process. Ziflow’s online proofing FAQ lists image files such as PNG, JPG, and PSD; documents such as PDF and DOCX; MP4 and MOV video; audio; HTML5 banners; and live webpages. It describes a shared workflow to upload, comment, compare versions, and route assets for review.
That workflow suits approval of a garment render, a campaign asset, a product video, or a webpage containing a design presentation. For a live webpage proof, Ziflow says reviewers can comment on page areas, check links, and capture full-page screenshots; staged reviews can route the page to stakeholders before publishing. For MP4 or MOV, the FAQ describes timecode-based comments and frame-precise change requests, tying feedback to a moment in the video.
Ziflow’s features page describes campaign-level review of images, documents, videos, audio files, and websites within one workflow. Ziflow is for approvals of those proof assets and cross-format feedback routing. It addresses a different review object from CLO-SET, whose focus is apparel samples and product content.
