pub const SWEEP_DEFAULT_TOLERANCE: f64 = 1e-4;Expand description
The centre-track deviation a station sweep is refined to when its caller
names none: 1e-4 mm. Read off the tolerance ladder in the record: the
loosest value at which both closed rings the plan named sit under 1e-6
relative on their closed forms (the rounded rectangle 4.8e-4 → 1.9e-7 at
211 stations from 81, the filleted skew quad 8.3e-4 → 7.4e-8 at 248 from
92), while the R = 10 ring keeps its 64 stations and every single-curve
fixture the landed geometry pins (a quarter arc at 32 stations reads
1.4e-7, a 350° arc 3.9e-5) stays under it and so bit-identical. One
decade tighter costs half again as many stations for a residual already
under 1e-7.
