A good fit for graded virtual-sample review
- CLO brings 2D pattern creation and editing together with 3D garment simulation, with still-image and turntable output options for review.
- Keep each approved render tied to its pattern revision, size, material setup, and production handoff file.
CLO is well suited to teams that want to connect pattern development with a clear visual review. Its combination of 2D pattern tools and 3D garment simulation supports an iterative workflow, while its still and turntable render options make it easier to present the garment in a format reviewers can use.
For a reliable approval, review the render alongside the pattern geometry, grading record, and material setup used to simulate the garment. Keep the visual output, garment size and material assumptions, and production pattern files together as one versioned review packet.
What should a graded-sample review include?
A review packet should let a designer judge the garment visually and let a pattern or production specialist trace that view to its source pattern. Grade rules describe how a pattern grows or shrinks between sizes. For a multi-size approval, retain the base size, graded size set, and the rules or measurement data used to create them alongside the image being reviewed.
A handoff record should identify the pattern elements that affect cutting, sewing, and later revisions. Sialkot Sample Masters, describing its apparel production bundle, lists pattern points, grade rules, notches, internal lines, and seam allowances in AAMA/ASTM DXF. The supplier describes DXF as a vendor-neutral exchange format and pairs it with native formats for different CAD systems.

| Review item | What to retain with the approved visual |
|---|---|
| Identity | Style, size, pattern revision, review date, and approval status |
| Shape and construction | Pattern pieces, seams, grainlines, notches, internal lines, and seam allowances |
| Size range | Base size, graded sizes, points of measure, and applicable grade rules |
| Material setup | Fabric identity and the physical or digital material properties used for simulation |
| Visual proof | Agreed camera views, colorway, output dimensions, and whether the deliverable is a still, image sequence, or video |
| Handoff | Exchange format, native CAD format when requested, layer mapping, scale proof, and file name |
File organization makes the visual record easier to trace. Smart Patternmaking’s CAD compatibility guide recommends a consistent CUT, SEW, GRAIN, NOTCH, DRILL, and ANNOTATION layer schema, with layers mapped to factory expectations. The guide recommends filenames that identify the style, base size, revision, and date, making the approved file easier to locate.
Material assumptions belong in the same approval record because drape and fit depend on the cloth represented in the simulation. Fabric weight, surface texture, and lighting all influence how a material appears. The practical review question is whether the digital material selected for the render represents the fabric expected for the sample, and whether enough material information is saved to reproduce that setup.
When does CLO fit the review workflow?
CLO is a good fit for technical teams that want to create and edit 2D patterns alongside a 3D garment simulation, then share the kind of render their reviewers find useful. Its pattern editing, measurement and grading tools, and Fabric-Aware Strain Maps for fit checking bring key parts of that work into one application workflow. Designers can refine garment geometry and assess the simulated result without losing sight of the underlying pattern.
The render choices are a concrete strength when the approval process has a defined visual format. CLO’s V-Ray render settings offer a still image, multiple turntable images showing the garment in 360 degrees, or a turntable video. Review leads can set the turntable image count to control the number of viewpoints, or use the video frame count and duration to shape the rotation clip.
For example, a technical designer checking sleeve shape and seam placement may prefer a still at a consistent angle, while a reviewer checking a side seam or back construction can use a turntable set. A merchandising reviewer may find a rotating video easier to view in a presentation. CLO’s V-Ray settings offer preset or custom image and video dimensions, and include a transparent-background option. Those settings help match renders to the space available in a review deck or comment system.
CLO’s V-Ray workflow also supports rendering all colorways from Colorway Mode. This can help reviewers compare approved color options in a consistent view and at consistent dimensions. Label each exported view with its style, size, pattern revision, fabric setup, and colorway so the image remains tied to the sample configuration.
CLO’s Pattern Drafter | Auto POM & Grading can generate points of measure (POM) from entered measurements and apply grading, with editable results. Fabric-Aware Strain Maps use fabric physical properties to determine and apply maximum wearable strain for fit checking. These tools can help teams connect entered measurements with the graded patterns and fit views reviewed across a sample range.
How do render settings change the approval packet?
Use this table to match the CLO render format and packaging settings to the review channel. Use a single still for a fixed checkpoint, a turntable image set when reviewers need several distinct angles, and a rotating video when they need continuous 360-degree motion. CLO’s render-properties guide documents all three options and lets a team set image or video dimensions; the settings also include transparent backgrounds.

| Approval need | CLO output option | Useful review use |
|---|---|---|
| Fixed view of a sample | Image, using current or custom view | Compare the same front, side, or back angle across pattern revisions |
| Multiple stable angles | Turntable Images, with a selected image count | Inspect details from several views and attach individual images to comments |
| Continuous rotation | Turntable Video, with frame count and duration | Present silhouette and construction changes in a short visual review |
| Color comparison | Render all Colorways from Colorway Mode, in the documented version 4.1.0 workflow | Keep a consistent view while reviewers compare color options |
| Layout-specific delivery | Preset or custom width and height, portrait or landscape, transparent background | Fit the render into a standard approval card, deck, or image layout |
Treat each image as one record in a larger packet. A render makes the surface and silhouette easier to discuss, while a DXF or native CAD handoff carries pattern information into production systems. CLO’s documentation lists patternmaking data workflows such as DXF, AI, and PDF; confirm that the format and included details meet the receiving team’s requirements.
Shortlist and verify the handoff
Start with the approval cycle your team runs most often, then test CLO with a representative style across the sizes, fabrics, views, and receiving-system formats you actually use.
- Choose CLO when your workflow benefits from combining 2D pattern creation and editing with 3D garment simulation, and reviewers need a still image, a 360-degree image sequence, or a turntable video.
- For the pilot, approve one known sample in at least the base size and a graded size. Save the view, pattern revision, measurements, simulated material, and colorway used for each approval.
- At handoff, open the exported file in the receiving CAD system and confirm scale, size labels, grade data, notches, grainlines, internal lines, seam allowances, annotations, and layer mapping. Use a PDF proof to check plotted scale and line visibility.
A representative pilot makes the tradeoffs visible before a team standardizes its review packet. Run a hem or fit adjustment, regenerate the same view for the same size and material, and ask both the reviewer and factory-side pattern specialist to trace that output to the correct revision. The pilot passes when reviewers can reproduce the approved view and trace it to the same size, material, and pattern revision in the receiving system.
FAQ
Does a high-quality render prove that a graded pattern is accurate?
No. Judge the render as a view of the simulated garment, and judge pattern accuracy from the underlying pattern and grading records.
Which output works best for a sample-review meeting?
A still image works for a fixed checkpoint, turntable images give reviewers multiple stable views, and video presents a continuous rotation. CLO documents all three V-Ray output types; choose according to how reviewers annotate and share feedback.
What should the factory receive with an approved render?
The factory should receive the approved pattern files in its required exchange or native CAD format, with the grade and construction details needed for production. Keep a PDF proof, pattern revision, size and measurement data, and the image used for approval in the same style record.
Should reviewers approve every graded size in 3D?
Review the sizes that matter to the fit risk and approval scope, including a base or sample size and sizes at the range ends when those represent meaningfully different fit conditions. Keep each reviewed size tied to its pattern revision and grade information so the approval record tracks the range under review.
