5.7a Changes

(Pro/DSS only) On the changes tab of the simulation control dialog the “Load Changes From…” button will allow multiple files to be selected. Same for data input and command output files.

If the time axis for graphs has been set it will not be reset by a new run unless that run starts before or ends after every currently loaded run.
When importing data from Excel files the name of the Tab rather than the name of the Excel file is used as the default dataset name.

PLE and Plus only. When using the Shadow Variable tool in a sketch by holding down he Shift key when clicking on a sketch location a defining variable and not a shadow variable will be added to the sketch. This makes it possible to write equations for FINAL TIME and TIME STEP.

Bug Fixes

In the equation editor the delimiter button [()] was not working on long equations.
Unchangeable constants were not coming up with the correct type selected in the equation editor.
Graphs comparing Constraints during reality check operations were incorrectly scaled and not readable.
Excel sheet names using international characters were not being recognized in the GET XLS calls.
DSS Only: Publishing models with the scramble option checked was not working properly.
DSS Only: Publishing Venapps would check the Other checkbox when the dialog first opened.
Limited time licenses installed on computers running non-English versions of Windows would sometimes fail to open.
When exporting a dataset the checkboxes to select time running down/across were linked to the checkboxes to put subscripts in a separate column.
Saving models with a password was not working.
Comments on Lookup variables would sometimes have extra \! delimiters added to them.
Subscript Element names requiring quotes were sometimes being incorrectly formatted when selecting variables for optimization and sensitivity testing.
When using the “Set” button on the Simulation Control Dialog the dataset names entered were not being recorded.
Reference mode data with reserved names (such as functions) would cause the data to fail to be loaded for display in graphs. Reference modes for subscripted variables were not being properly retained. Clean and reform could also cause reference modes to be lost.
In the Equation Editor subscript equivalences were not being entered and Time Bases not properly marked (Pro/DSS only) .
