# work with 2D bezier curves and add some extrusion (typically the width of your wood) while modeling your plates
# enable the Export Autocad DXF exporter Addon (File->User Preferences-> AddOn-> search DXF)
# before exporting: reduce the extrusion to 0, switch back your curves to 3D mode (Data panel-> shape-> 3D)
# Convert your bezier curves to Mesh (Alt-C)
# File -> Export -> Autocad (.dxf)
Somehow the DXF exported directly is not recognized by LaserWork, so you have to open it in Illustrator and save again as .dxf and make sure it's R13/LT95 format
