Parametric garment engineering

From pattern files to living engineering models.

FTT does not replace pattern CAD. It captures patterns from existing tools, preserves their original structure and adds a new intelligence layer that connects geometry, measurements, grading rules and technical documentation.

  • Any CAD workflow
  • Original layers preserved
  • POM-driven geometry
  • Automatic grading propagation
  • AI assisted

Existing pattern geometry remains intact. FTT adds the engineering relationships.

Past → future

Stop updating documents. Start engineering products.

Today, a single garment change often has to be repeated across spreadsheets, pattern files, sketches and tech packs. Parametric engineering turns those separate documents into connected outputs of the same technical model.

Stop updating documents. Start engineering products.

The disconnected way

One change. Five manual updates.

  • Measurement table Value changed manually
  • Pattern file Geometry corrected separately
  • Grading sheet Rules copied across sizes
  • Sketch + tech pack Annotations and tables replaced

Duplicated data · disconnected versions · silent inconsistencies · knowledge held by individuals

The parametric way

One engineering change. Every connected output updates.

  • Canonical POM CHEST WIDTH
  • Base value 54.0 cm
  • Grading law +2.0 / size
  • Size break From XL

Pattern · grading · sketch dimensions · tech pack · model audit

The keystone

The pattern engine is the foundation of the parametric model.

Inspired by modern mechanical engineering systems, FTT treats each pattern as more than geometry. Measurements become controlled parameters, grading becomes a rule system and every dependent output can be regenerated from the same source.

  1. 1
    Capture, do not replace

    Import pattern files from existing CAD environments and preserve their native layers and geometry.

  2. 2
    Add an intelligence layer

    Anchor POMs, seams, constraints and technical relationships on a dedicated FTT layer.

  3. 3
    Drive geometry with data

    Change a measurement in the table and the connected pattern geometry updates accordingly.

  4. 4
    Regrade from verified laws

    Apply informed grading rules, including size-specific breaks, and regenerate the size range.

  5. 5
    Re-export into the existing workflow

    The technical team keeps using its established tools while FTT provides the engineering intelligence between them.

Review before apply

Controlled propagation

Every update follows engineering rules. The technician stays in control.

FTT does not automate blindly. Changes propagate only through defined relationships, grading laws and validated dependencies. AI can propose, detect and accelerate; technical approval remains human.

Why it matters

Less repetitive work

Technical teams stop rebuilding the same change in several disconnected files.

Fewer silent errors

Sketch, measurements, grading and pattern can be audited against the same engineering definition.

Higher product quality

Changes remain coherent across the full size range, including informed breaks and exceptions.

A new foundation

Not another pattern tool. The engineering layer between your technical systems.

Pattern CAD, spreadsheets, sketches and tech packs remain part of the workflow. FTT connects them around one parametric garment model so that every document is generated from controlled technical relationships instead of maintained as an isolated truth.

Complement existing CAD

Work with the pattern tools already used by technical teams and suppliers.

Preserve expertise

Convert individual technical knowledge into explicit, reusable engineering rules.

Scale with integrity

One technician or one thousand: every model follows the same controlled technical foundation.

Parametric textile engineering

The garment should behave like an engineering model, not a folder of documents.

FTT brings the parametric logic of modern engineering systems to textile product development—without forcing technical teams to abandon the tools they already know.
