How to I rotate an object in the X plane (1 reply)

I have just started learning Inventor and I have run into a problem.

In inventor, and in Meshlab, the object is orientated with the top as I expect it.

When I add it to the platter in Slic3r the object is rotated, to the object is on it's side, and I cannot find a command to rotate it and have the bottom on the bottom, not on it's side. I can find a command to rotate it about a vertical axis, but not the horizontal one.

Any ideas?
