DXF is a standard file format of industrial CAD patterns and stores 2D pattern information. DXF is currently available in Yuka, Gerber, Lectra, StyleCAD, Optitex, PAD System, etc. 

DXF-AAMA, DXF-ASTM, Standard DXF files of AutoCAD and Adobe Illustrator files are compatible with most 2D CAD softwares. 

Import (Add)

1. Click the File ▶ Import / Import (Add) / Export ▶ DXF in the top menu. 
     
2. Select the DXF file and click Open.
      

3. Set the details and click OK.

   Option		Description
   Basic	File Format	Select the format of the DXF file being imported: Standard DXF / AAMA / ASTM. (Previously auto-detected by CLO)
   	Scale	Select the unit used in the pattern CAD.
   	Rotation	Rotate the entire pattern clockwise/counterclockwise.
   Option	Import Pattern Annotation	Import Pattern Annotation information together.
   	Auto-Trace as Internal Line	The entire baseline is traced as an Internal Line.
   	Swap Cutting Line and Sewing Line	Check this option when the pattern's Cutting lines and Sewing lines are changed.   * The Cutting line and Sewing line may change depending on the export option setting of the pattern CAD.
   		Include Notches	When changing the Sewing line and Cutting Line, the notch is moved together.
   	Import Notch to	Decide the imported notch placement on Seam Allowance, Pattern Outline, or Both.
   		Notch Position	Fixed notch at a specific position, or place a notch at a position by ratio.
   	Auto Distribute	Closely rearrange the patterns in the DXF file.
   	Optimize All Curve Points	Optimizes the number of curve points in the DXF file.
   	Convert to Seam Allowance	Import CAD seam allowance to CLO seam allowance. The default setting is applied to the type of start, end or edge seam allowance that is not supported by CLO.  This option has been removed from the menu starting from version 2026.1. DXF Seam Allowance is now automatically read and converted into Custom Seam Allowance (Locked status). Unlock it for further editing.
   	Remove Non-Grading Points	Optimize the number of points by deleting Straight/Curve Points that have no grading information. This option is only required for AAMA-format DXF files which is different from CLO's default curve points.

Export

1. Click the File ▶ Export ▶ DXF in the top menu. 
    
2. Set the file name, save the path, and click OK. 
    

3. Set the details and click OK. 

   Option		Description
   Basic	Select Pattern	Select the size group you want to export from among the grading size groups applied to the file. Only one Size Group can be selected and exported per file.
   	DXF Format	Set the export format: DXF-AAMA, DXF-ASTM, Standard DXF.  (If you previously used "Gerber (DXF-AAMA)", select DXF-AAMA — it produces the same output)
   	Size format	Export grading information included in the DXF file, or separately as a Rule File. (If you previously used "Rule File (Lectra)", select Rule File — it is the same option)
   	Scale	Set the unit of the pattern.
   	Rotation	Rotate the entire pattern clockwise/counterclockwise.
   Option	Export without Grading	Export the current size only, excluding grading information.
   	Export without Baselines	Export patterns except for baselines.
   	Duplicate Notch on Seam Allowance	Duplicate the notch on the outline of the pattern to the seam allowance.
   	Swap Cutting Line and Sewing Line	The type of sewing line and the cutting line defined in CLO and Pattern CAD may be different. In this case, when exporting to DXF, the cutting line and the sewing line are replaced and exported.
   	Convert Curve Point to Straight Point (AI Only)	When DXF is imported from AI (Adobe Illustrator), the curve information does not come in properly, which may distort part of the pattern. In this case, it can be solved by converting all the curved points of the pattern to straight points.
   	Optimize All Curve Points	Easily modify the curve by optimizing the number of curve points added on the line segment.
   	Export Pattern Bounding Box (Single Bounding Box/ Separate Pattern Bounding Box)	By exporting the pattern with the bounding box, conveniently edit the image when working in Photoshop, Illustrator, etc.
   	Export Selected Patterns	Only the selected pattern is exported not the entire pattern.
