threaded holes in a pipeline

[telemako71]

Good morning

if I subtract a threaded hole from a body that stands in the same part of the hole in the body will be a threaded hole....but if I subtract the same hole from a body that belongs to another part the hole will be a simple hole , I lose the threaded properties.... in practice every time in a paroduct insert a screw between two plates I have to apply the threaded feature hole of the plate also
Is this how it works or do I have to change some catechism?

check if the "technological results" are present, in case there were no fairies above the partbody to recreate them
