PCS 1.x can do smoothing....
oh.. and Blender is officially anti-supported by PCS because of the problems it causes (it exports bad geometry constantly)
No it doesn't. Not anymore. I've explained this to you before Kaz.

One of the early versions of Blender had a problem with the dxf export format. Back then that was all it could effectively export, and this caused a number of problems all over the place, not just with PCS. That issue has
long since been fixed, and besides which it can now effectively export many other formats.
Out of all the ships I've built over the years, I've only had PCS choke on a couple - and the problem was
always caused by TS. I can say with complete confidence that if you put a bit of effort in, PCS is perfectly happy with Blender exported models.
(Also, remember that it's now open source. What would you think of someone if they began ranting about how PCS 1.0 used to create some bad collision data? You'd tell them to use a newer one. Same deal here I should think.)
Nuke: See, that reason is fair enough - Blender's imports are not great, so it doesn't suit your needs. No reason at all to say it sucks.

All those format importers/exporters were written by various users over the years, and annoyingly enough, the cob import/export appears to be the least complete of all of them. That said, you will almost definitely lose heirarchy no matter what format you use.
