corian seams

I am fabricating my first Corian countertops. I have read the Corian fabrication manual. But it does not say if the seaming is done good side up or upside down. I am thinking it should be done good side up so you can be sure both pieces line up correctly. Does anyone know the proper way to do this? Thanks.

In the shop I do them upside down So I can epoxy the patch across the seam for strength before I turn it over.
On the jobsite it can only be done right side up.

Actually I do everything I can ,bottom side up before it is turned over. Edging, patches, buildup, and bowl.
Solid surface is heavy enough that I only want to handle as little as possible.
Hope this helps.

Thanks Tom, but how do you get the edge of the two pieces flush with each other when it is upside down?

I get every thing on tables or stands level as I can and spaced up off the table with 3/4 scrap so that the epoxy squeeze out does not touch table.
Dry fit the seam and shim wherever necessary.
