Is there an easy way to place my imported fbx file on the original origin that i have created in sketchup?

The imported 3D model is placed to a position that is defined in the fbx file. The easiest way to check the position is to put a breakpoint after the Model3D is read and check it's Bounds to get a bounding box.

If this is different from what you have defined in SketchUp, then check if there is any special export setting for this.
