okay, so I will first try to enrich the doubleClicked with a pop up.

I found this example # obj.addProperty("App::PropertyLinkSub", "PartName", "Part", "Reference to name of part").PartName = (part, ['Name']) # obj.addProperty("App::PropertyLinkSub", "Volume", "Part", "Reference to volume of p...

Thank you werner, it works fine. My mistake: I added the __getstate__ only to the viewprovider. another question in this context: the ViewProvider has a method doubleClicked are there other calls possible too: mouseOver, ... and is it possible to bind an own contextmenu to a viewprovider object whic...

So the index of the Face/Edge/Vertex will not change once selected. My workaround actually is to make a copy of the selected subobject a...

Is it possible to have a toolbar or a menu entry for all workbenches?

toolbars are defined per workbench

@wmayer? Is it possible to extend the Drawing/App/FeatureProjection in a way that it creates a projection only of the selected face of a shape with direction perpendicular to the selected face to get the true size of that face on the drawing? this would simplify the process of getting an unfold of a...

here is the example of a 3 piston radial motor

there are still some problems with speed and renumbering the vertixes in the sketch.

Hallo Yorik, if you will integrate the macro of jonathan I have an other macro too https://github.com/microelly2/freeCAD_macro/blob/master/m09_camera_along_line.FCMacro It redirects the camera given two points or a line. Together with the drawing::project shape they can support unfolding an drawing ...
