Looks like you have double standards. Model with continuity - not good, but to have wry cylinder - it is good. Model for molding is pedant - but have artifacts is normal. You do not know what this detail will be and how it fits etc... But you are absolutley know what is good and what is wrong. You are experts in this area and I want to belive you... But some times it looks like you try to protect this model by any means. Anyway I have no all objective information about this subject and do not want to read tea leaves. So I stop discussing. Peace
