Key Takeaway
- In CLO, edits made in the 2D pattern window are automatically reflected in the 3D garment window.
- Measurement-led drafting in CLO can generate points of measure and apply grading, with editable pattern results.
- Fit Maps give designers visual tools for reviewing garment fit in simulation.
When a sample collection needs a sleeve-pitch or waistband-curve revision, CLO keeps the 2D pattern and 3D garment views connected: edits in the pattern window are reflected in the garment view for review. Apparel developers use CLO to create and edit 2D patterns and simulate garments on avatars using fabric properties. Before cutting physical yardage, teams can review pattern revisions, size grading, and fabric behavior on virtual samples.
5-Step 2D-to-3D Sample Review Routine in CLO
- Create patterns for a chosen pattern type from measurement points or flat sketches using CLO’s Pattern Drafter.
- Enter measurements during pattern drafting to generate points of measure (POMs) and apply grading; Pattern Drafter results can be edited.
- Modify 2D pattern lines as needed. Adjustments made in the 2D window automatically synchronize with the 3D window. Editing a 2D pattern during simulation ends that simulation, so simulate the updated garment to review the change.
- Simulate each graded size and compare garment and avatar views together in Grading Review. If pattern geometry changes after simulation, simulate the affected size again.
- Connect patternmaking to production data with Auto POM & Grading, nesting-based fabric consumption and costing estimates, BOM export, DXF, AI, and PDF import/export, plus Pattern Information with per-pattern revision history and 2D Grading Review across all grading sizes.
Syncing 2D Pattern Edits to 3D Simulation
When a pattern maker adjusts a dart or hemline during a fit session, CLO reflects the 2D edit in the 3D garment window for review. If the edit is made during simulation, the change synchronizes and the simulation ends; the garment can then be simulated again to inspect the revised silhouette.
Measurement-Based Grading and Size Review
A size run needs both a grading method and a way to review how the shapes look across sizes. CLO supports more than one approach:
- In Pattern Drafter, teams can enter full measurement values for each size or specify grading increments between sizes.
- CLO’s documented grading tools support distance, ratio-based, and multi-field adjustments.
- Pattern Drafter’s grading results can be edited.
Reviewing Fit with Fit Maps
A simulated garment gives teams a way to review overall proportions and inspect areas where a woven yoke may bind or an activewear panel may overstretch. CLO’s Fit Maps provide several views for that review. The Strain Map shows garment stretch as a percentage and, in Fabric Mode, uses a wearable stretch limit calculated from the fabric’s physical properties; users can adjust that limit manually.
Designers can choose from four garment fit maps: the Fit Map indicates garment tightness, including areas marked as tight or not wearable; the Strain Map shows garment stretch under external force as a percentage; the Stress Map displays stress on the garment, including force along the fabric grain per unit area; and the Pressure Map shows external pressure exerted by the garment on the avatar. Global Mode uses the same scale for every fabric, while Fabric Mode uses each fabric’s calculated wearable stretch limit.
CLO states that fabrics in its Library and fabrics created with the Fabric Kit have about 90% accuracy. The stated accuracy may differ when a fabric’s physical properties are modified.
How CLO Compares on Pattern Sync and Fit Review
CLO, Optitex, and VStitcher each combine 2D pattern work with 3D garment review, grading, and fit-related analysis.
| Software | 2D-to-3D Pattern Updates | Measurement & Size Grading | Fit Maps |
|---|---|---|---|
| CLO | Changes made in the 2D pattern window are automatically reflected in the 3D garment window; an edit during simulation synchronizes and ends the simulation. | Supports distance, ratio-based, and multi-field adjustments; Pattern Drafter accepts full measurements by size or increments, supports editable grading results, and can generate POMs during drafting. | Four maps (Fit, Strain, Stress, Pressure); the Strain Map offers Global and Fabric modes, with Fabric Mode using a wearable stretch limit based on fabric physical properties. |
| Optitex | Integrated 2D pattern design and 3D sample visualization; Optitex describes changes made to the 3D sample as directly affecting the 2D pattern. | Advanced grading tools grade patterns simultaneously and visualize draped results in 3D for virtual samples in various sizes. | Garment fit analysis is based on fabric properties; the virtual tension map displays values for tension, distance, and stretch between cloth and avatar. |
| VStitcher | Supports work in both 2D drafting and 3D draping environments, with garment visualization and refinement. | Supports fitting garments on customizable 3D avatars and grading across sizes. | Hovering over a garment in the tension map displays Max Stretch measurements in the length and width directions. |

FAQ
Does CLO offer onboarding and fabric digitalization support for enterprise teams starting 3D sample workflows?
Yes. CLO’s Enterprise plan includes live demos, a tailored implementation package, onboarding and customized training, a dedicated 3D specialist, corporate direct support, digital transformation consulting, fabric digitalization service availability, and access to exclusive events. Pricing is available by contacting CLO.
Do CLO Fit Maps guarantee how a physical garment will fit and feel?
Fit Maps help teams assess garment fit in simulation using fabric-property inputs. They’re design aids, not guarantees of physical fit or comfort, so teams should consider input accuracy and how the garment is tested when reviewing results.
