A practical starting point for patternmaker-led sample review
- Use CLO to create and edit 2D patterns, review the garment in 3D, and prepare a still image, multiple turntable views, or a rotating video.
- Keep the approved visual connected to the style, size, pattern revision, material inputs, and handoff file used for review.
- Confirm that the pattern file imports as expected in the receiving system before sign-off.
When a sample review begins with changes to 2D pattern pieces, CLO brings the pattern work and 3D garment view into one workflow. Its documented V-Ray render options also let teams choose a still, a set of turntable images, or a turntable video. Together, these capabilities make CLO a natural place to build an approval packet around both the garment’s appearance and the pattern behind it.
A render helps reviewers assess silhouette, color, print placement, and presentation. It is not a substitute for the technical record. Keep the pattern revision, size and grading information, material assumptions, and handoff test with the visual so feedback stays tied to the version the team actually reviewed.
Build the review around both the visual and the pattern record
A useful sample-review packet answers two questions: what does the proposed garment look like, and which technical pattern produced that view? A clear image makes it easier to discuss silhouette, details, and overall appearance. A traceable pattern record helps the patternmaker and receiving team identify the pieces, size, revision, construction marks, grading, and material assumptions behind the image.

| Review item | What to send or record | Why it helps the decision |
|---|---|---|
| Approval visual | One still, several defined angles, or a rotating view | Gives reviewers a clear format for commenting on silhouette, details, and appearance |
| Pattern identity | Style name, base size, revision, date, and linked native project or agreed exchange file | Ties feedback to the exact pattern version under review |
| Pattern geometry and construction | Pattern pieces, seams, grainlines, notches, drill points, and internal lines | Makes the construction cues behind the 3D image available for technical review |
| Size and measurement record | Size shown, points of measure (POMs), grade rules, and graded sizes included | Clarifies which size the image represents and how it relates to the base pattern |
| Material and simulation inputs | Fabric identity and the physical or visual material settings used for the review | Helps reviewers interpret drape, stretch, surface appearance, and fit indications |
| Handoff check | Target file format, layer mapping, and a test import in the receiving system | Confirms that marks and pattern data reach the next team in a usable form |
Use a consistent layer schema for CUT, SEW, GRAIN, NOTCH, DRILL, and ANNOTATION, along with clear file names for traceability. Use the receiving team’s requirements as the final check for a handoff.
Material information belongs in the packet because a 3D image reflects the inputs used to create it. Record the chosen fabric asset and material settings alongside the pattern revision. That makes it easier to tell whether a change in appearance came from a pattern update, a different fabric input, or a change in the presentation setup.
CLO: match the render to the review format
CLO is well suited to a patternmaker-led review because its documented workflow pairs 2D pattern creation and editing with 3D garment simulation. CLO’s Creator’s Field Guide describes the 2D Pattern Window as the workspace for creating and editing patterns and sewing, and the 3D Garment Window as the workspace for arranging, draping, and visualizing the garment. This connection lets the team assess a pattern adjustment in the context of the simulated garment.
CLO’s V-Ray Render Image/Video Properties guide lists three final render media: Image, Turntable Images, and Turntable Video. Image output can use the current view or a custom view. Turntable Images creates multiple views around the garment, while Turntable Video creates a rotating 360-degree video; the guide notes that the video’s frame-count setting affects the smoothness of rotation.
That flexibility is useful when the review format is agreed in advance. Send a still for a decision centered on a key view, a set of angles when reviewers need to inspect the garment from several sides, or a rotation video to communicate its overall shape. The guide also describes image and video presets or custom dimensions, a transparent-background option, and a render-all-colorways setting. Check the available options in the workflow being used.
These settings shape how reviewers see the garment; the technical pattern record remains essential for checking pattern accuracy. Name the render with the same style, size, and revision identifiers as the pattern record, and preserve the material and view settings used for sign-off. That simple discipline makes it much easier to revisit a decision later.
Make the shortlist against the receiving workflow
For this patternmaker-led workflow, begin by testing CLO with a representative style and the visual format reviewers expect. The central question is whether the team can make its usual pattern edits, review the resulting 3D garment, and deliver the required image and pattern handoff with the right information attached.
Then run one representative style through a short acceptance test:
- Choose a style with pattern features your team often changes, such as a hem, seam, dart, or print placement.
- Set the base size, any graded sizes, POMs, fabric asset, and review avatar or fit model used by the team.
- Make a planned 2D revision and confirm that the 3D view updates as expected.
- Export the approval visual and the pattern file or agreed exchange package.
- Open the pattern output in the receiving system and check geometry, seams, grainlines, notches, grading, internal lines, and the agreed material record.
- Have the reviewer approve the visual and technical revision together, using the same style and revision identifiers in both records.
Choose the render format to suit the decision, not just the presentation. A still may be enough for a focused view; multiple angles or a rotation can help when reviewers need to assess the garment more broadly. In every case, keep the chosen image linked to the pattern and material inputs that produced it.
FAQ
Does a 3D render prove that the production pattern is accurate?
No. A render shows the garment’s simulated appearance for the chosen pattern, material, avatar, and settings. Check the pattern and its handoff separately before treating it as production-ready.
Should reviewers see more than the base size?
Yes, when the approval decision covers a size range. Identify the size or sizes represented in the render and include the associated graded pattern or POM record. This helps reviewers distinguish approval of a base-size sample from a review of the wider range.
What should the team put in a DXF handoff test?
Test a pattern that includes the details your factory needs, then check its piece geometry, grade information, notches, internal lines, and layer mapping in the receiving system. The receiving team’s import settings determine the final acceptance check.
