The DXF file format is a universal format that can store both 2D drawings and 3D objects. This makes it suitable for transferring drawings and 3D models between different programs.

 

In our case, the CUTL service calculates the cutting cost of parts — meaning that any lines in the drawing are interpreted as cutting paths. Therefore, to obtain an accurate calculation result, you should not simply save your drawing as a DXF file “as is.” Instead, you need to remove all elements that are not part of the actual part, such as:

• Dimension lines

• Text labels, unless they are part of the design itself

• Construction or auxiliary lines

• If the drawing was generated as a view from a 3D model, it is recommended to break the link with the model and remove any service or reference elements.

 

Additionally, keep in mind that the DXF format has evolved over many years — new objects and features have been added. Therefore, if your software allows you to select a DXF version, it’s best to choose AutoCAD 2012 (DXF version 2010) or earlier. Newer versions can also be processed by our service, but complex multi-layer drawings may be read incorrectly.
