Issue with mixed metric nominal diameter matching values

[jdflipside]

Hello all,

I'm having some issues connecting an 8" imperial flange to a 225mm metric flange using a mixed metric simple joint with the matching values specified (8, 225 nominal diameter). The error message doesn't seem to be a connection error, rather just appears with "Cannot find a part of required size in the spec", almost like it's not even checking the matching values.

Oddly enough, when we turn off mixed metric and attempt the same connection in metric (200, 225 nominal diameter) to the same flange it will connect.

Is there anything obvious that we're doing wrong here? Is it a software limitation? Do we somehow need to specify the units?

I've been through this forum post:
