Wahey! Hi, Ian. Long time no etc.
Yup, that's the best way I found when I was starting out, once you get the idea though, you'll be throwing objects around with ease in TG.
Also, if you always leave a heightfield shader set to the default position you'll be able to find your imported object really easily because objects import to x0 y0 z0, or, the bottom left of your heightfield.
If you wanted to make it appear right in front of you(if you're on the other side of the planet, far from point 0,0,0, or such) you can import it, then create a sphere in TG and copy the co-ords from that to your object's. Spheres always import right in front of your current camera. Just delete/disable/hide from render the sphere afterwards, it's only a marker.
