Working With Data:

PSModel Data Files:

All PSModel data files end with the extension .psm_data.

2) Or, right click on the Graph Window, and click Save As on the popup menu.  Enter a file name in the Save As dialog box that opens.

Selecting Data Rows:

To select or highlight a single data row:

1) Left click on a data row.  This highlights the data row and graphs the propeller curves for the propeller geometry shown in that row.

To select or highlight multiple data rows:

2) Or, press the Ctrl key while left clicking the mouse on data rows.  This highlights both contiguous and non contiguous rows of data.

Selected or highlighted data rows can be copied to the clipboard for subsequent paste operations.  To copy a data row or rows, do one of the following:
