Initial Design Table Parameters

Hi,

This is hopefully going to be straight forward for someone to answer...

My need is as follows: (simplified)

1 Assembly containing 6 parts

Assembly is a cuboid made up of the six parts

I'd like to place variables/parameters into the Assembly Model Destign Table to control the following:

Width / Depth / Height and most importantly Thickness

Can someone please help? I can see it's very easy, but I'm failing somewhere...

Cheers,

M
