Importing a single model

I’m having trouble importing a model that I made and exported as a *.DAE. Whenever I import it into another *.blend file, it always seems to be “attached” to another piece in the scene (usually the ground plane). Has anyone else experienced something like this? Is there a way to import a file into another and have it be detached from the ground plane? I know I’ve been able to do it before, I’m just not sure if I accidentally changed a setting or something happened to cause this effect. Thanks.
