symmetry_feature

yes, I'd like that option as well. A curve can be without breadth in the mathematical sense, but a vector object can be produced as a physical object and the dimensions of that thing do matter for what I'm using said vectors for. Since that creeps into feature request, should I take that there?

The way that alters the curves isn't really an option for me. There is no full-size measurement option?

Here's a series of examples for various options (random character chosen, this is a font A, not someone's specific logo): In other words, a setting that measures the dimensions of the entire shape, stroke included, is what I am looking for. The width of both object, stroke (separately, for production reasons), and overall object (again, for production reasons), are important. (I'm only really including the third option as a permutation of the settings; it's come in handy for original art but I'm not suggesting it's a fix). In the instance of actually getting someone's vectors, this is extra important-- the pre-existing form of the logo will probably have aligned-to-center stroke lines and that won't be something that you can just decide not to follow. Caveat about the enamel pin example: of course those cutouts are a bit ridiculous, but since I wanted an example addressing how outlines are achieved, I'm not bothering with that, it's just not relevant.

Searched through the forums, found someone else's single workaround but no reference to such a setting, read through Settings and document setup. I thought it would be a setting for Transform but that doesn't seem to be the case. I'm working on an enamel pin design and it's difficult to get the full dimensions of a pin (or make them fit a dimension) when I have to either constantly commit the outer stroke to vectors or some other workaround. Difficult to keep nondestructive and it can be a lot of extra unnecessary work.

I also would appreciate this. Inkscape has a mirroring tool that allows you to define an axis of symmetry for a given curve, which you can then configure/edit. It's one of the things I do there and then bring into Affinity later so that I can make things work. I appreciate that some users work around it with symbols so that they can stay in Affinity, but the workaround isn't really a solution.
