Assembly drven by design table

Looking for some help on how to set up this asseembly, somebackground info.

I have a box that is rectangular, it has open sides as standard,there are then a number of configurations where side plates areadded, end plates are added and side and end plates are added tomake corner sections.

These boxes are stacked together side by side and on top of eachother to form a larger cube, dimensioned X,Y and Z. These largercubes will always have side panels and end plates and corner unitsaourn the outside faces, and the centre of these larger cubes willbe filled in with the standard open sided cubes.

I have the assembly of the individual box made, and configurationsdriven by a design table for the side, end and corner pieces.

What I would like to do is have a new assembly with a layout sketchof X,Y,and Z dimensions, these would be the dimensions of thelarger cube made up of the smaller boxes, then have a design tabledrive the assembly with these dimensions and generate the largercube putting the correct boxes in the correct places.

Really looking for some info on where to start with this, so anyideas would be much appreciated. Here is hoping that M. G. Martinezmight have a little look at this as from reading his past posts hemay have some good ideas.

Thanks in advance.
