Recurring alex-3d-skills (alexchunlin) errors, by impact

  1. 15 of 11 purchased-part entries are "estimated" hand-typed envelopes; the issue checks a 16,847-part STEP catalog as a source of vendor geometry.MCAD · Agent failure · 1 report74
  2. 2An agent CAD skills repo built on build123d. In #29, `cad bom` keeps its own STOCK table with rows for M2, M2.5, M3 and M4 but none for M5. The comment says it is "the same table as cadcheck's fasteners.stock_lengths", which does have M5. The lookup returns None, so "cad bom never flags an M5 screw at a length nobody stocks." Proposed fix is to read the table from one place.MCAD · Agent failure · 1 report74
  3. 3Cross-checked hole and head sizes against bd_warehouse's ISO tables. Most rows match, a few are off by 0.18 to 0.4 mm, and bd_warehouse is wrong too (its iso7046 M4/M5 rows equal its iso2009 rows), so they settle each row against the standard or a test print.MCAD · Agent failure · 1 report74
