@letterror @timahrens @justvanrossum Yeah, that’s what I’m getting at, I think. Just’s animated visualisation really nicely shows how stretching a complex web of axes in one dimension alters the distances between intersections within that web. But that’s not what happens when one changes the unit scale of a variable font axis. The design space isn’t being stretched. You’re just changing the resolution of that axis. The design space is bounded by the glyphs not by the numeric length of the axes connecting them. You only change the shape of the design space if you change the glyphs or their relative locations (e.g. redefining an axies extreme or the relative location of an intersection, either in the masters source or via avar).
