Thanx again mateo... yes I do the same... but still original obj when imported into Poser. I think the problem is that I am exporting the obj from Carrara with local coordinates switched on. If I save with local coordinates switched off, it works fine, but then I have to go through all the hassle of rescaling and repositioning the object in Poser. I was hoping the obj would import into Poser in its duplicated state, then I would just have to make a single (move it left) adjustment. It would be so much easier if there was a mirror or flip action in Poser, but as far as I am aware there isn't one.
