 * ''Notes:
 * As long as the name of the created structure (and its parts) is unchanged, any workflow interactions will just update the structure. If you change any names, a new structure will be created each time.
 * It is not required to have KiCad running to update KiCad project files. Actually, KiCad does not even have to be installed on the PC.
 * The standard approach is to use the same sketch on both sides, KiCad and Freecad. Any changes will be synchronized to the other application. This is the most natural and clean way to work with KicadStepUp . However, this causes a problem if you want to use any of the following features in your sketch to define your PCB shape: dimensions, geometry constraints, construction geometry (blue lines), or external linked geometry. There is no clean way to do this, because KiCad does not know any of those features. That means that on the round trip between the applications, any of those features will be deleted. There is no real solution for that problem, just a selection of one of several workarounds. So if you want to use any of those features, that means you must define the PCB shape in FreeCAD only and sync in one direction toward KiCad. Any outline changes done in KiCad need to be added manually on the FreeCAD side. This might make sense, e.g. if future changes from the mechanical side are much more likely than from the electrical side. There several ways to do it:
 * Put the design sketch inside the KicadStepUp structure, and select "replace PCB and keep Sketch in curr. doc" every time you import back from Kicad.
 * Keep the design sketch outside the KicadStepUp structure. Ignore the sketch imported from KiCad.
 * The second choice has the advantage that changes in KiCad can be traced to the original sketch, and the FreeCAD sketch is protected against an accidentally wrong import choice. The described workflow uses this approach to make sure the issue is well understood. From there it's easy to switch to modifying the KicadStepUp supplied sketch with none of the more advanced FreeCAD features.
 * To use KicadStepUp with a FreeCAD assembly (> V0.19) you could add a new file for the PCB. After the workflow above has been run once add the 3D object for the PCB to your assembly like any other mechanical part. Make sure you save the file when it was updated by KicadStepUp (Important: KicadStepUp writes to FreeCAD memory, not to FreeCAD files).
