name: Option<&str>,
) -> Result<BrepSolid, String>Expand description
Blend a chain of conjugated edges with one rolling-ball blend face (Golovanov §6.9.5: all conjugated edges processed together). A CLOSED chain (stadium rim, T-pipe saddle) welds into a periodic blend; an OPEN chain (line->arc->line capped by end faces) rolls a clamped blend that terminates in a transverse edge on each end face.
