How to export sheetmetal part geometry to laser cutter

How to export sheet metal cutting geometry (dxf) to laser and avoid cutting tool stopping on each line end?

Do as follows:

1. Make a flattened view from the sheet metal part (if there is nothing to unbend, make a top view projection)

2. File - Export - Save to another format - select "dxf" or dwg

3. Give file name

4. Select from Settings dialog "DXFtoCNC2". This converts individual lines and arcs to continuous polylines.
