Headers in the modification sizing dialogue (tab results) for bevel gears was not shown correctly. This is now fixed.

SP2 Bending of the shaft and flank line modifications in the operating backlash calculation
Option 'Take into account the bending of the shaft and flank line corrections' was not considered correctly in the operating backlash calculation. This was limited to special cases, when load spectrum with more than 1 bin was defined, but 'Don't consider load spectrum' or 'Only take 1 bin into account' was selected in tab Rating. This is fixed now.

SP2 Grinding notch factor calculation for internal gears using form grinding
In special case, the grinding notch for the internal gear was not calculated correctly. This only appeared for the form grinded gear, using VDI 2737 for the form factors calculation. The issue is fixed now.

SP2 Set back possibility to create 3 or 4 gear chains with coaxial internal gear as last element
Due the exception handling, it was not possible to create 3 or 4 gear chains with coaxial internal gear as last element, this is now fixed.

SP2 The calculation sub modules
The calculation sub modules status was not saved in the file before, this is now fixed. It is also set on load.

SP2 When a shaft calculation is locked, a dot can be added at the end, but not inserted in the middle
When extending a locked shaft in the sketcher before, a dot would be created but not a cylinder behind, so no element could be added on the dot. Now the user can still extend the shaft at the end, but the dot is created directly on the next available grid point. And no dot can be inserted in the middle of a locked shaft.

SP2 When deleting a idler gear in the sketcher, the related gear calculations are also removed
When deleting a idler gear, its shaft or shaft calculation in the sketcher, the related gear calculations are now also removed. This is a special sketcher feature, when doing it in the tree, the transverse trees parents remain in the model.

SP2 WITHDRAWN - Improvement: Export a KISSdesign model to REXS

SP2 Symbols for axial support in shaft editor were too large

SP2 For larger groove width diameters, the notch factors for the shaft strength calculation are not considered correctly
In some models that had larger groove width diameters, parts of the surrounding shaft section were also considered as groove instead of just a smooth shaft section.

SP2 Prevent importing invalid input in the bevel gear position converter in the shaft editor
In the shaft editor, the bevel gear converter only produces reasonable

results if all values yk, hae and txo are defined. Thus it should not be

possible to run the calculation if they are not set properly. In

addition, the title should be changed to in order to indicated, that the

converter is for the positioning only.

SP2 Crash in element tree fixed
KISSsoft crashes when removing notch elements of a shaft and adding another cylinder afterwards via context menu. This is fixed.

SP2 Radial bearing stiffness was not properly calculated in some cases
The radial stiffness which is shown in the bearing report was not correct for some cases.

SP2 Texts with some %s can't be evaluated, are not translated.

SP1 Minor error in operating pressure angle calculation of shaft module
For gear elements with a helix angle and multiple meshes, the operation pressure angle of the individual meshes was not calculated properly leading to minor deviations from the corresponding value in the gear calculation.

SP1 Sizing without any elements caused a crash
When running the shaft sizing function without any contour elements present, KISSsoft crashed

SP1 Buckling of shafts with fixed intermediate supports
Buckling of shafts with fixed intermediate supports was crashing. This is now fixed. Further than that, the result of the buckling calculation using the new shaft solver does not give buckling safety, but rather the Euler's critical buckling load. The corresponding texts are also corrected.

SP1 Speed and load cycle number in the report was wrong for the calculation with one load bin
For calculation for one load bin was the speed and load cycle number wrong in the report, the influence of the speed factor wasn't in.

SP1 Inclusion of point mass properties in the dynamic calculation, even if the mass is zero.
In some cases it is necessary to add a moment of inertia property in a dynamic analysis of a shaft, without defining any mass (e.g. for torsional vibration studies). Up to now zero mass elements were ignored in the dynamic analysis. This is now corrected.

SP1 Fixed shaft order in the shaft calculation tree vs KISSsys tree
The order of the shafts in the shaft calculation was different than the one in KISSsys when renaming or opening a previously saved file with edited shaft names. This is now fixed, the shaft calculation tree should always have the same shaft order as the KISSsys tree (otherwise some results might differ).

SP1 Report generation for the Load Spectrum template fixed
Same as for the main strength calculation in KISSsys, the report generated by the Load spectrum template was not working. This is now fixed. As there are multiple reports generated by KISSsys, an additional docx file is created for each of them so that they can then be opened by a simple double click.
