What clients say:

The fact that XLRotor is imbedded in Microsoft Excel shortens the learning curve for new users and makes it easy to import and export data to other applications. The charting functions are very familiar and enhanced functionality can be obtained by using Visual Basic calls. The numerous example problems included with XLRotor can be used to kick start most modeling efforts.
