The question is probably due to my poor understanding of Inkscape and/or SVG. Is there a reason why standalone nodes do not exist? What I mean is an abstract non-renderable point which can still be worked with. Examples of use being for instance:
- Reproducing a bitmap diagram. You place the nodes at critical points and complete the drawing.
- Using such points to facilitate geometric constructions by having real objects representing mathematical points. That is you place certain points on the figure which can be moved but are not drawn. Then you create the figure based on those points.
I realise that there are plenty of workarounds such as using dots and hiding them, or using zero lenght paths etc... But they seem to me to be exactly that: workarounds.
Perhaps it is something non-existing in the SVG specification though I don't really understand why a node cannot exist without a path. Or perhaps it very well exists, though if that's the case, I cannot find it. I would appreciate any form of pointer, be it search terms, a webpage or a direct explanation.
PS: my main interest would be to vectorize an existing bitmap diagram without feeiling that I'm emploing hacks and workarounds.
