ISO 15065:2005 countersink outer diameter (Dc) not auto-populated for ISO hole standard
Problem: When creating a countersink hole using the ISO standard (e.g. M2x0.4, Clearance, Close Fit), the outer diameter field is left blank (Ø 0.00) and requires manual entry.
Impact: Every time a countersink hole is created with the ISO standard, the user is forced to stop, look up the correct value in ISO 15065:2005 Table 1, and manually enter it. This breaks the workflow and introduces a risk of human error — especially since all other parameters are already handled automatically by Creo.
ISO Requirements: The outer diameter field is not a design choice — it is calculated directly from the pilot diameter and the 90° angle that ISO already defines. Creo has all the information needed to fill this field automatically.
Optional Expected behavior: The outer diameter should be auto-populated from ISO 15065:2005 Table 1, which fully specifies this value (Dc = 4.4–4.5 mm for M2). All other fields — pilot hole diameter, angle, and depth — are correctly auto-filled from the same standard.
Proof of inconsistency: When using the UNF standard, all fields including the outer diameter are populated automatically. This confirms the issue is specific to the ISO implementation, not a deliberate design decision.
