Open contour in DXF when exporting sheet metal

How can I create a sheet metal model that will produce an open cut contour when exported to DXF? This is essentially a laser beam incision that begins cutting the metal at one point and stops at another, leaving a strip with a width equal to the cut width, but in DXF, it simply appears as a segment.
Open geometry should be mapped to layer 0 in DXF, just like regular closed contours.
Making a thin cut and manually deleting segments until only a line remains is not suitable.
Drawing a sketch on the surface that will be mapped to another layer and then transferring it to layer 0 in DXF is not suitable.
Could someone share a working secret on how to create model geometry that will produce this result? Thank you.


:writing_hand: For example, shown here are metal strips with small crossbars that allow the entire stack of strips to be bent in one go after cutting, and then broken off individually during assembly. A single cut is faster and cheaper.
