Scalings glyphs as group with metrics?

[George_Thomas]

You can do that by scaling the UPM. This thread has information from Mekkablue about that:

Font UPM size like in FontLab?

Let’s say you are designing a font in 1000 UPM. Scale to UPM changes the resolution of units. If you scale it to 2000, the outline that was 1000 before scaling becomes 2000, and the visual size at given font size stays the same. If you scale UPM to whatever value in instance, it will look of the same size, only different in outline quality (try scaling to 50 to see what I mean). UnitPerEm does not change your outline or metrics. If you simply change UPM to 2000, that 1000 unit outline stays 10…
