Convert a Excel Block Model in Shapefile

[SamirMohallem]

Hello Comunity,

I'm using ArcGIS to convert and Share all my Mining Works... One of most important things in Mining sector are the Block Models. Simplifying,This model consist in a table with collums X,Y,Z (center of the block), block dimension (dimx, dimy, dimz) and other info, like chemical analysis.. Normally in a BLock model we have 12-30 columms and 100k to 2million lines. 

I've been trying to export a model to a shapefile file for a while, creating a block model like the one below (to be used in 3dviews). You can see final pits and other structures in dwg/shp...  

I'm including a Block Model example attached. If anyone can give a light...

Thanks
