View ports??? We're not in AutoCAD anymore, come out and see the light.
Drawings go onto a layer. Are you sure that layer is turned on in your layout book?
It may also be shooting off the page? Check the anchor point of your drawings and try a center anchor point instead if using the views internal anchor.
If it's neither of those we'll keep looking.
And please don't double post your questions. There's not ~that~ many of us!
Cheers,
