The Outline drawings are provided in two formats: .exe and .tif.
The .exe files are self-extracting zip files created from the .dxf files.
They are smaller than the .dxf files and the download time will be shorter.
The .tif files are for viewing and plotting only. They are not vector images
and the geometry can not be modified. To read the details on large drawings,
the .tif files will require the use of a third party viewer. For further
