Thanks for tha advice guys.

DustRider: I have found that manually inputting a value on import makes the object large in the assemble room but it is still remains really tiny in the model room (no matter what value I input).

trav: If I scale the model up in the model room it also scales up in the assemble room. So I end up with a massive model in the assemble room (which is not practical)

The problem is the disparity in size between the assemble room & the model room. In the aseemble room it can be really quite large but still miniscule in the model room.

I have found that I get more practical results using the transposer plugin, so I will have to use that for now. However, it would be nice if I could work this problem out because a simple .obj import is sometimes preferable to me than a Transposer one. This way I can change some of the vertex import parameters depending on the type of work I am doing (allowing me to select polymesh parts by name etc.).

Anytime I see something screech across a room and latch onto someone's neck, and the guy screams and tries to get it off, I have to laugh, because what is that thing?
