– Resolved a problem that could cause CADFEKO_BATCH to crash when called from the GUI.
– Resolved an issue that caused large spaces to be displayed in the output on the Executing runfeko dialog.
– Resolved an issue where CADFEKO wrongly passed process priority to RUNFEKO for sequential jobs.
– Made various corrections and improvements to the saving process, in particular, what files are saved when processes are still busy performing calculations.
– When opening .cfx files created in CADFEKO [LEGACY] or older versions of CADFEKO, the initial view will be zoomed to the extents of the model.

– Fixed a crash on Linux when zooming out in the cable harness schematic view.
– Resolved an issue where opening a model created in CADFEKO [LEGACY] or older versions of CADFEKO could open with a port having unconnected terminals in the schematic circuit.
– Resolved an issue where the dialog that indicates that the application is busy converting a legacy model was hidden behind the splash screen.
– Models with incorrect coaxial cable definitions or incorrect 3D anisotropic medium definitions may have resulted in an error while converting from a legacy model.
– Corrected a problem with number formatting where a decimal separator instead of a space was used as thousands separator.
– CAD fixing with the remove small feature tool, simplify part representation tool or the repair edge tool could have resulted in large faces being removed if the faces were inside solid regions and not touching any of the region boundaries.
– Resolved an assertion failing when removing rows from the Constrained Surface dialog.
– Fixed an assertion failure which occurred intermittently when opening the Create S-parameters dialog.
– Resolved an assertion failure when duplicating an S-parameter configuration that had no ports defined.
– Introduced more descriptive error messages when regions are unable to mesh.
– Resolved various problems creating FEM volume meshes with symmetry.

– Restored twenty three antennas to the component library that were previously only available in CADFEKO [LEGACY].
– Resolved an issue with the align tool being populated incorrectly when adding a component from the Component Library to an existing project.
– Creating a union of layered isotropic dielectric faces and anisotropic dielectric regions will no longer trigger an assert.
– Fixed a crash when saving a model with a suspect wire port.
– Resolved a crash when re-opening the project filter in the same session where settings were applied to the project filter while another model was open.
– Resolved an issue where an Unnamed error message dialog was shown instead of a pop-up error message when applying an invalid change on any dialog.
– Updated the geometry vertex rendering to only render the vertices and not extra vertices from tessellation.
– Fixed an assertion failure that was triggered when modifying multiple entities at the same time and a tri-state value was invalid or empty.
– Fixed a crash that occurred on Linux when modifying the properties on multiple faces
– Fixed a crash that occurred on Linux when modifying the numerical Green’s function (NGF) settings.
– Fixed a failure when loading models created in CADFEKO [LEGACY] or older versions of CADFEKO containing subtracted geometry parts.
– Fixed mesh refinement rules not being applied when it has a non-default workplane set.
– Mesh overlay display is disabled while tools, other than those where mesh settings can be modified or mesh information is displayed, are open.
– Resolved an issue with Connectivity not displaying in the 3D view immediately upon being enabled.
– Resolved an issue with snap points being rendered in the 3D view when no snap points were expected or used.
– Improved the accuracy of windscreen work surface snapping to allow using point entry to create surface lines.
– Resolved an assertion that failed upon geometry modification of a wire referenced by a wire port, where the modification results in the wire becoming an edge.
– Prevented certain actions on child geometry parts through the GUI and API, including converting to primitive, exploding, reversing of normals and unlinking the mesh.
– Added validation to prevent an assertion failing when attempting to path sweep geometry along a disjoint path.
– Added validation to prevent the deletion of a local mesh setting definition that is used in the local mesh settings of a part.
– Resolved an issue where a view with two start pages could have resulted if a model failed to load, with the view being split into two sections. The application had to be restarted to return the view to normal.
– Saving the model is no longer part of the protect and unprotect model feature.
– Protected model validation incorrectly used solution methods on parts that are not root-level parts and could have incorrectly stated that a model cannot be validated.
– Resolved an assertion that failed when meshing a protected model with a larger model unit than the model it was imported into.
– Relaxed optimisation constraint validation so that validation is only done on active constraints.
– Use alphabetical ordering for optimisation collections under the Construction tab in the model tree.
– Resolved an issue where the cut of the cutplane was not facing the user by default.
– Corrected the orientation of the Theta and Phi angles when using rotation to define a cutplane.
– Removed unused options from the Geometry Importer Tool. ODB++ format can be imported using the PCB Import Tool. Gerber format is not currently supported.
– Resolved an issue with incomplete version information being written out to .pre file.
– Resolved a hang when opening a model that was created and saved using a script.
– Resolved an issue with the script editor where the full filename did not get displayed for filenames containing multiple full stops.
– Resolved a crash that could be triggered by clicking on the Close button on the application macro dialog while the macro is running.
