Object (solid) direction

Hi people,

How can I set the x,y direction of a solid in Rhino?

Ive imported some step files. I want to nest them in Grasshopper with Opennest. I dont want the objects to rotate in the nesting, so ive set rotations to 1. But the solids already have a direction. The step files were created in Spaceclaim and thats where they proberly got the x,y direction.
