BRCM Basic cutting plane

Hi All,

How do I create a basic cutting plane:

E.G. I have a building with cable trays inside, now I want to print the top view. In order to see the cable trays i need to cut below the roof.

Previously in the AutoCAD world, I went into the layout area,  created  a -VPORTS and then with 3dclip moved the clipping plane around,  what is the BRCM equivalent to this procedure?

Thanks in advance
