Build 7.5.3
Modifications

  • Resolved an issue for the "Date-of-Failure" format of the Warranty Folio when calculating a forecast and the starting date for the forecast is beyond the end date of the model.
  • Resolved an issue for the "Usage" format of the Warranty Folio where updating the forecast calculations did not update the plot.
  • Resolved an issue for the "Date-of-Failure" format of the Warranty Folio when running under German settings.
  • Resolved an issue with an incorrect message being displayed for the Non-Parametric RDA Folio when the confidence level entered is equal to 0.5.
  • Resolved an issue when deleting multiple data sheets from the Data Folio.
  • Resolved an issue with the calculation in the QCP when used within the diagram and the associated Data Folios did not have any data.
  • Resolved an issue when plotting Free-Form data, where the points did not show up under certain circumstances.
  • Added a visual sign to the Plot Sheet to show whether the plot is in or out of sync with the calculation of the corresponding Data Folio.

Build 7.5.2
Modifications

  • Resolved an issue for the "Nevada" format of the Warranty folio when the "Suspend After" option was used.

  • Resolved an issue where the degradation folio was recalculated but the linked data folio's parameters were not.
  • Resolved an issue where after transferring data from a Degradation folio to a Standard folio, the Standard folio is hidden behind the Degradation folio.
  • Resolved an issue when using Non-Parametric RDA and calculating Mean Cumulative Function with confidence intervals included; application calculated all values correctly but the confidence bounds shown was always 95%.

  • Resolved an issue with the Gamma parameter estimation for the 3 Parameter Weibull distribution.

Build 7.1.3
Modifications

  • Resolved an issue with plots showing blank for customers having installed BlockSim or BlockSim FTI release 6.5.4. This was caused due to Weibull/BlockSim compatibility considerations.

  • Added scroll bar to the Warnings Window.

Build 7.1.1
Modifications

  • Added language support for Chinese, French, German, Portuguese and Spanish.
  • Resolved an issue when "Alter Parameters and Recalculate" menu became disabled after altering a parameter.

Modifications

  • Resolved an issue with lines being jagged when printing plots.
  • Added the ability to copy a general spreadsheet chart or image to the clipboard.

Build 7.0.4
Modifications

  • Resolved an issue with importing multiplots when opening Weibull++ 6 files.
  • Resolved an issue when PARAMNAME and PARAMETER functions in the spreadsheet did not return the value for Eta when Weibull 1-Parameter distribution was used.
