about

nx_step_parse.nx -- R1a STEP (ISO-10303-21) STRUCTURE parser LIB (no main; gated by nx_step_parse_gate). The explodeview-parity keystone: STEP is explodeview.com's ENTIRE input format and a named CAD gap since 07-01 (nx_step_import.nx never existed). SCOPE v0 = Part-21 lexing + entity table + the PRODUCT STRUCTURE spine: PRODUCT / PRODUCT_DEFINITION_FORMATION / PRODUCT_DEFINITION / NEXT_ASSEMBLY_USAGE_OCCURRENCE -> assembly tree + BOM. Geometry tessellation (analytic faces then NURBS) = R1b, its own rung. Lexer rules honored: quoted strings (double-quote-escape by doubling), /* */ comments, complex instances ( NAME(..)NAME(..) ), balanced-paren argument spans. The hash character (35) is matched NUMERICALLY -- never appears in an nx string literal (compiler gotcha). ctx st: *i64 slots: 0=buf 1=n 2=id[] 3=nameoff[] 4=namelen[] 5=argoff[] 6=arglen[] 7=count 8=cap. license_tier: ORIGINAL
