When I import a Poser file into Vue, it shows up very, very small. I can expand it by grabbing the edges of the "box" and stretching it, but this isn't very precise. Is there any way to specifically expand something by a given amount (say, for example, 205%) I'm not really familiar with Vue, so there has to be something I'm overlooking here.

Indeed, you are overlooking something. Of course there is a numerical input for most of the values. These are "under" the material preview you see to the top right. There is another tab there zo switch to the numerical inputs. Try it out.
