Fastener to feature diameter
Fastener to feature diameter
(OP)
Is there anyway to relate a fastener to the hole diameter in mechanica? I would like to link them so I can study the effects of changing the fastener diameter. I'm not seeing a straight forward way with the fastener dialog.

'neat fit', that is, the same diameter. To specify a fastener hole clearance or interference, you might specify that someplace else like the Load window/interface.

Turns out there's some kind of bug that stops optimization studies in their tracks when doing this. If you use fastener shear stress as a limit it causes a problem. The measure on the fastener shear stress disappears between steps and then the study fails with an internal engine error. If you bring the definition up the limits on fastener shear stress are missing.
Global studies work fine.
Short version: You can't optimize based on fastener shear stress.
