can you split an assembly

Hi,

Attached is a word doc showing what I am trying to do.

I have a Plate Girder comprising of top & bottom Flanges, web plate and stiffeners / bearing pads.

Originally this girder was going to be delivered in one length.

Now however we want to split this girder into two half's and weld back together at site.

How can I split this assembly into the two half's, keeping the stiffener / bearing pads on the relevant half's.

The top bottom and web plates were originally in one length, however when i split the assembly these items will need new Item numbers as the split will not be central.

So items will be unique.

Is it possible to split this in two and re-name the relevant components.

Thanks
