Modify VBA code

1. Create unique .dxf files for left, right and middle faces. Only if "Show?" checkbox is ticked. So if all checkboxes are ticked then Left will have own .dxf, right own .dxf and middle own .dxf 2. Coordinates for Left side should be mirrored on X-axis on output. e.g. if widht = 550 and coordinate for first hole is x=50 then output should be x = 550-50 = 500. Do not mirror Y coordinate. 3. See inside macro for FileSaveNames - I have created variables for this that you can use for naming different .dxf 4. Top and bottom shall have same .dxf together. 5. Make a checkbox "open dxf". If ticked it should launch each dxf when created.
