Key Features

Optitex provides a robust and integrated feature set covering the entire technical design and production chain. Each module is designed to deliver technical accuracy and professional-grade outputs.

2D Pattern Design

• Create, edit, grade, and prepare apparel patterns with advanced CAD tools built for technical pattern work.

• The Dynamic Measurement Chart supports direct import of Excel-based measurement data for automatic creation of pattern and PDS files, reducing manual input and minimizing inconsistencies.

• New safeguards, such as confirmation prompts when switching between sew and cut lines, protect pattern integrity by reducing unintended geometry changes.

3D Garment Simulation

• Visualize patterns on digital models to evaluate silhouette, fit, and construction before producing physical samples.

• Integrates photorealistic 3D rendering to assess fit, drape, and appearance, significantly reducing the need for physical sample iterations.

Marker and Production Workflows

• Prepare manufacturing-oriented outputs that support material planning, cutting, and production handoff.

• Nest ++ Pro has been updated with an enhanced nesting algorithm that increases processing speed while improving material efficiency.

• Automated vertical bump line batch commands and expanded group/shading batch commands in Marker strengthen consistency across repeated operations.

Connected Design Data

• Keep 2D patterns and 3D garments linked so changes flow through the development process more consistently.

• The Production Diagram tool has been refined to improve documentation control. When a graded PDS file is selected, only the base size is imported, calculating the marker board area to reduce unnecessary visual density.

• O/Cloud, the cloud-based companion, enables remote collaboration and integration with PLM and ERP systems.

Professional Tech Pack Export

• Tech Pack Essentials is now available to all users without additional purchase, expanding access to standardized production documentation tools.

• New batch commands within Print & Cut enable automated generation of PDF and DXF files, including control over page orientation and defined output paths.

How to Use Optitex O/26: A Step-by-Step Workflow

A typical workflow in Optitex follows a logical progression from pattern creation to production output.

1. Pattern Development (2D PDS)

• Import or Draft: Start by importing a block or creating a new pattern from scratch in the 2D Pattern Design Suite (PDS).

• Digitize: Using graded specifications, utilize the Dynamic Measurement Chart to import Excel data and automatically create PDS files.

• Edit: Use the comprehensive toolset to add darts, notches, and seam allowances. The O/26 update allows for L-notches to be exported as true L-shaped notches for downstream compatibility.

2. 3D Garment Simulation

• Avatar Selection: Select a 3D avatar that matches your target fit model.

• Simulate: Run the simulation to visualize how the pattern will look on a body. Optitex’s 3D engine assesses drape and fit, using defined fabric parameters.

• Material Application: Use the Material Converter to apply realistic textures and TIFF-based material maps to the digital garment.

3. Production & Marker Preparation

• Production Diagram: Once the design is approved, open the Production Diagram to prepare documentation. The tool now imports only the base size to ensure clarity for production teams.

• Nesting: Send patterns to the Marker module. Utilize Nest ++ Pro with its enhanced algorithm to maximize material yield and reduce waste.

• Batch Commands: Apply batch commands for vertical bump lines, grouping, and shading to standardize layout preparation.
