Hi, first time using this forum so hopefully someone can help-

the problem im having is that when i mate two conical cylinders- i would expect the default mate to be concentric.

however SW 2014 is doing the coincident mate as default, and if coincident isnt possible (due to other mates preventing it) its then opting for a parallel mate.

The parts im mating ive been working on for a long time now (through SW 2011, 2012 and 2013) and never had this issue and these parts havent changed at all so its a new problem that has only arisen from the 2014 upgrade.

I missed the first two 2014 upgrades so went straight from 2013 to 2014 sp2.  Dont know why that would matter but it may help.

Its hardly the worst problem ever but given the assemblies im working on have a lot of concentric mates and its making the whole thing a lot slower.

Any help would be much appreciated- is this a issue or is it something i can alter in the options?

thanks in advance
