blizzard- sorry I'm late chimming in on this and I hope the site will still forward this. There's another answer to your problem. example: you have primative one shaped and sized as you want. You have Primative 2 shaped and sized. Position p-2 where you want it in relation with p-1. Then export the project as an obj file- making sure in the drop down screen that both primatives are checked for exporting. Then when you import the obj file, both primatives will stay the way you shaped them and in the postion you placed them in. I've been in the process of building a train entirely in poser usine both Poser primatives and primative sets I've collected over the last few years and I've found that some primatives just don't like each other! This export-import idea seems to work everytime. Hoipe it helps.
