Appendix A: Using the SDG MTL File Tool
The MTL File Tool is designed to allow users to easily create .mtl files to upload into the SDG. If a gradation
report completed in accordance with ASTM D 422 is available, all of the information on that report can be
entered into the table on the Gradation file tool and a .mtl file will automatically be generated and saved to the
Desktop of your PC. This file can then be transferred to a USB flash drive and installed directly into the SDG
as explained on page 18.
