Key Takeaway
- CLO synchronizes 2D pattern edits with the 3D garment view, allowing you to simulate and review changes within the same workspace.
- CLO's Pattern Drafter supports points of measure and measurement-based grading, with editable results.
- Fit maps include a Strain Map view that uses fabric properties to set maximum wearable strain limits; simulated fit still depends on accurate fabric inputs and how the garment is tested.
Transitioning a seasonal sample collection from flat pattern blocks to a first 3D rollout often stalls when small adjustments require constant file re-imports or decoupled rendering steps. When a patternmaker shifts a jacket shoulder seam or tweaks a knit top neckline, waiting to see how that change alters the three-dimensional hang breaks the concentration needed for rapid fitting. In CLO, imported DXF patterns can be edited in 2D and reviewed through 3D simulation without repeatedly transferring files between applications. Alongside this 2D-to-3D update, CLO supports generating points of measure and applying grading from measurements, as well as simulating garment fit and drape using garments, avatars, patterns, and fabric properties. For downstream collaboration and review of 3D assets, CLO-SET is a separate workspace that complements CLO's garment-creation and simulation workflow.
Connected 2D Pattern Editing and 3D Simulation
Bringing legacy pattern libraries into a new 3D environment only works if the software reads existing production files cleanly and reacts immediately to alterations. CLO supports both 2D pattern creation and editing alongside 3D garment simulation, centering its workflow on real-time garment creation so you can visualize fabric, fit, and silhouette as you work. Edits to imported DXF patterns synchronize with the 3D view. Editing a 2D pattern stops an active simulation, so run simulation again to assess the updated fit and drape.
For teams moving patterns between existing 2D CAD seats and 3D review, file compatibility affects how much cleanup happens after import. CLO supports DXF import/export, AI/PDF import, and PDF export, helping connect its workflow with patternmaking tools such as Lectra, Gerber, and Optitex, as well as Illustrator.
Measurement-Based Drafting and Grading
Generating base blocks and size runs from spec sheets is useful when the resulting pattern pieces remain editable for style-specific shaping. CLO's Pattern Drafter can generate points of measure (POM) and apply grading from measurements, with editable results. Related tools include a POM Calculator and formula-based editing across multiple grading fields.
Pattern Drafter supports drafting from CLO avatar measurements and includes detail blocks such as pockets and hoods. AI Pattern Drafter (Beta) supports image and text inputs to generate starting patterns for further review and refinement. support.clo3d.com
Avatar Fit Maps and Simulation Limits
CLO simulates garment fit and drape using garments, avatars, patterns, and fabric properties. Its fit inspection tools include fit maps, with a Strain Map view that displays the garment's stretch ratio. In the fabric-based Strain Map view, the maximum wearable strain is determined and applied using the fabric's physical properties.
Digital verification has operational limits. CLO simulation, fit maps, pressure views, and material controls can support virtual garment review, but do not guarantee physical fit or comfort. Results depend on the accuracy of fabric input values and how the garment is tested.
3D Apparel CAD Feature Comparison
Teams planning a first 3D rollout may compare how CLO, Browzwear VStitcher, and Style3D Studio handle linked pattern edits, size grading, and avatar inspection.

FAQ
Can CLO import DXF notches onto pattern outlines and seam allowances?
Yes. CLO supports importing DXF notches onto the pattern outline, the seam allowance, or both.
Does CLO's Strain Map account for the specific stretch limits of activewear or stretch fabrics?
The fabric-based Strain Map view determines and applies the maximum wearable strain using the fabric's physical properties. The result is a simulation aid, not a guarantee of physical fit or comfort.
Do active university students qualify for a CLO individual subscription and student discount?
Active students enrolled at accredited universities qualify for a CLO individual subscription. They can receive a student discount after appropriate enrollment documentation is submitted to and verified by the CLO user support team.
What is the difference between CLO Academy and CLO Verified?
CLO Academy is 100% free for all individual subscribers, including active student subscribers. It provides learning access but does not currently offer quizzes or certificates of completion. CLO Verified is a separate, paid certification exam. Candidates who pass receive an official CLO certificate verifying proficiency in the software version tested.
How are CLO and Marvelous Designer related?
They are sibling products that share garment-simulation technology but serve different workflows. Marvelous Designer is primarily for animation and gaming, while CLO is optimized for fashion and apparel product development.
