Recently FreeCAD 0.17 has became the new stable release.
Very near the latest pre-stable, FreeCAD switched also to OCC7.2
This new version of the mechanical kernel of FreeCAD is offering some improvements, but unfortunately introduced a bug in exporting STEP hierarchical models with FreeCAD that didn’t get caught before the stable get released.
With this update of KSU (kicad StepUp version 18.104.22.168) I’ve introduced some temporary fixes, to be able to export a simplified version of hierarchical STEP models.
NB this version is available only through the FC Tools Addon Installer Menu ATM.
From the KSU main toolbar:
there are two buttons that can already simplify the Hierarchy to a single object (union) or to a single group of objects (compound).
Those buttons can help in exporting the KSU imported board manually, using the standard FC menu.
Moreover I improved the option to export to STEP a hierarchy through the export button and the checkbox option, aligning the exporting behavior similar to the one available in FC 0.16.
A STEP model can then be loaded through the Import button
or through the standard Import or Open FC Menu.
If a single level hierarchy object is loaded in FC through the menu, it is useful that the simplified mode of loading is unchecked to load the model with its hierarchy and colors(it is available in FC STEP Import/Export preferences).
KSU has also added a new small Toolbar with some utilities … among those there is the option to toggle this property value.
Feel free to test it and give me feedback.
