Small Python script witch can make 2d from selected 3D objects in Blender. Useful for furniture. For 2D I use qCad (free version).

bpy.ops.object.transform_apply(location=True, rotation=True, scale=True)
bpy.ops.object.origin_set(type='ORIGIN_CENTER_OF_VOLUME', center='MEDIAN')
# iterate through the selected objects
