IFC Models - Move IFC in vertical space

Is there a way to move IFC models in the vertical direction? I imported some models, truck, excavator, tree, from Sketchup and I am able to move them in the x and y but not in the z axis.

here is a post from another (same ?)member that A.Sharp did a little video on.

You likely have to move the block because the Sketchup file is placed at the origin of the block that it replaces in the 3D view. I will check that in the morning for you.
