What to do after you create a 3D render

Why a 3D render is not enough for production

CLO3D and Style3D solve the hardest visual problem: showing exactly how a garment drapes, fits, and moves before cutting a single metre of fabric. But a render file contains simulation data, not factory data. A manufacturer needs a technical flat, labelled measurement points, fabric and trim callouts, stitch specifications, and a graded size chart — none of which export automatically from a 3D file.

Bridging that gap manually means re-drawing the flat in Illustrator, transcribing measurements from the simulation, and building a bill of materials from scratch. For most studios, that takes days per style. The 3D investment speeds up design approval but does nothing to compress the production bottleneck downstream.

Step 1: Export your approved render

Once the 3D garment is approved, export a clean front, back, and side render at high resolution. Avoid composited marketing shots — use the neutral-background, flat-lit technical render that shows construction clearly. A colourway render and a garment-on-avatar render are both useful; the technical one is what feeds into your spec.

In CLO3D, use the render mode with subdivision on and GPU rendering for clean edge detail. In Style3D, export from the Technical view for the flattest interpretation of the silhouette.

Step 2: Feed the render into SpecForm OS

Upload the render directly to SpecForm OS. The AI reads the garment silhouette, construction seams, and visible details to produce a structured tech pack draft: technical flats for front, back, and key details; AI-suggested points of measure; a bill of materials seeded from the visible materials; and construction callout annotations.

Because SpecForm OS was trained on production-grade specs, it interprets construction intent from the render — stitch lines, pocket placements, collar construction — and translates that into spec language a factory reads directly. The draft is editable at every point before export.

Step 3: Review and refine the measurement table

The AI-suggested measurements are a starting point, not a final spec. Cross-reference them against the CLO3D or Style3D simulation measurements, which are available in the garment properties panel of both tools. Where the render-derived annotations differ from your simulation data, override them in the SpecForm OS measurement table directly.

For graded sizes, SpecForm OS generates a size chart draft you extend across your size run. If your 3D software has grade rules applied, use those as your source of truth and populate the chart accordingly.

Step 4: Confirm the bill of materials

Your 3D simulation already defines fabric weights and finishes — that is how CLO3D and Style3D simulate drape. Map those simulation materials to real-world equivalents in the BOM: fabric type, weight in GSM, fiber content, supplier reference, and care instructions. Add trims, closures, labels, and packaging that the simulation doesn't track.

SpecForm OS auto-drafts the BOM from the render. Your job at this step is to confirm or correct each line with your actual sourcing data, so the factory is costing real materials, not AI guesses.

Step 5: Add construction details and export

Seam types, stitch specifications, hem allowances, and finishing details are the final layer. Many of these are visible in the render — SpecForm OS annotates what it can see — but construction intent that isn't surface-visible (interlining, fusing, understitching) must be added manually.

Once the spec is complete, export to PDF. The output is a factory-ready tech pack: technical flats, labelled measurement table, graded size chart, BOM, and construction callouts in a single document.

The complete 3D-to-production workflow

Across the two tools, the full pipeline looks like this:

• Design and simulate in CLO3D or Style3D until the garment is approved.
• Export a clean technical render (front, back, side) from the 3D software.
• Upload the render to SpecForm OS and review the auto-generated tech pack draft.
• Cross-reference measurements against the 3D simulation data and correct where needed.
• Confirm and complete the bill of materials with real sourcing data.
• Add any construction details not visible in the render.
• Export the finished tech pack to PDF and send to factory for costing and sampling.
