Many of these spreadsheets are macro-enabled to provide advanced features, and won't run properly unless you click the "Enable Content" button that appears with the security warning upon opening the files. Microsoft always warns when macros are present in a workbook. The macros are used only to supplement the engineering calculations, dynamic sketches, and other advanced features. All spreadsheets are compatible with the desktop version of Microsoft Excel 2007 or later.
