pub const OPENROCKET_DEFAULT_RADIUS_M: f64 = 0.025;Expand description
The radius OpenRocket gives an automatic body radius that has no fixed radius anywhere along its chain to take, in meters: its default radius, 25 mm.
OpenRocket’s maintainers write that such a radius is “the default radius”
(openrocket#1988)
and that a tube left with nothing to take “reverts to default diameter”
(#1992); a user guesses that default at
“1.969 in” of diameter (#871), which is
50.0 mm. No document states the number, so it was measured: OpenRocket 24.12, run on fifteen
small designs by validation/oracles/openrocket/automatic_radius.py, settles every such tube,
lone nose cone and lone transition at 0.025 m and ignores any number cached after auto
(validation/fixtures/ork/openrocket-automatic-radius.json, ADR-054).
hpr departs from OpenRocket in one place, on purpose: where a nose cone’s base or a transition’s end looks at another automatic radius, OpenRocket 24.12 settles on −1 m, which no geometry can take. hpr gives it this default too, so the chain is one radius end to end.
