Note that Poser does work to a different scale from most other 3D programs, so an object in a .3ds will look gigantic in comparison to the Poser figures. Where it's a model of a real object. of known dimensions, I import the .3ds and set the scale of the Poser object to 5%, which is a reasonable start. Then I scale a simple box, X Y and Z, to match the target size, and adjust the object scale so it just fits. Then the grouping tool, to make a copy of the object, and save that copy as a Poser prop. It's long-winded, and I know I've not explained this in detail. There's other ways to re-scale. But different versions of Power use slightly different scales, and you might prefer to use a different scale again. For a historical setting, most Poser characters are rather tall at the official scale. ("Scale" gets different meanings, but the important one here is the real-world distance represented by a value of 1 in the .obj file.)
