Hi Dimitar, I added a Fill mode: Frame:
So far it is a customizable “Wireframe Modifier”. It apply the component with an uniform thickness along the edges (variable with shapekeys). For the faces it basically perform an inset face, while for the boundaries it was a bit more complicated.
So far I haven’t done anything for the inner part, but, if the component is not close, you can try to use Cap Holes… Not really flexible, but better than nothing
