Toolbox gear problem

Hey there, im realy struggling with this problem.

I am using the gears from the toolbox to design a gear box. (many gears)

My problem is that the gears from the toolbox are shell features. For example, a section profile is taken through the gear, the gear appears to be hollow.

This is creating problems when i import a section view of my design into a drawing.

Any ideas of how to remedy this? Perhaps change a shell feature to a soild feature?

Any suggestions will be much appreciated,

Thanks

Wes
