Go to File > Export (or use the dedicated Data Exchange / Interoperability module depending on your Modaris version).

Converting is crucial for across platforms. If you design patterns in Lectra Modaris but your supplier uses Optitex, Gerber, or another system, they likely require a standard DXF file. The conversion ensures that your design data is communicated accurately, avoiding costly errors and production delays.

A "full" conversion is often difficult because DXF files can lose proprietary Lectra data. Watch out for these common issues: Layer Organization

Converting Lectra MDL files to DXF enables users to:

Websites like Convertio or CloudConvert sometimes support MDL.

Method 1: Using Native Lectra Modaris Interoperability (Recommended)

Launch your receiving software (e.g., Optitex).

Finding the right converter is critical. Here are the primary solutions available, ranked by their suitability and capability for achieving a "full" conversion.

To solve this, the apparel industry developed specialized extensions of the DXF format:

The most reliable way to convert MDL to DXF is directly through Lectra Modaris

If you do not have access to Lectra software, specialized third-party tools can handle batch conversions. reaConverter

By following these recommendations and understanding the challenges and solutions associated with converting Lectra MDL to DXF, textile and fashion companies can ensure seamless communication between different software systems and hardware devices, ultimately improving their design, production, and manufacturing processes.

Clean up the MDL file in Modaris first (remove unused points, construction lines, or ghost pieces). Verify the grading table is correct and attached.
