pub const VERTEX_MATCH_FLOOR: f64 = 5e-3;Expand description
Absolute floor (mm) of the edge-endpoint-vs-vertex identity band used by
BrepSolid::validate: below this a curve end and its topological vertex
ARE the same point (vendor export precision), above it the model is asked to
state the meeting exactly.
Single-sourced because the STEP importer must heal precisely the misses this
band refuses: healing less leaves an import that cannot validate, healing
more rewrites vendor geometry the kernel already accepts as-is (see
heal_imported_edge_endpoints).
