What is the best method for managing large grid surface datasets for use in gINT Fences?

Question

Hi all, 
 
 What is the best method for managing large grid surface datasets for use in gINT Fences? 
 Also, if I have elevation data in meters for a grid and want to display in feet in gINT, I wonder if there is a fairly easy method to do this? 
 
 We have a bunch of subsurface data that we'd like to plot on fences. We can convert in the form of GRIDS but it seems like my file sizes get really big for the GRIDs and gINT won't always import because they are big. 
 I was converting to a GRID ASCII in Surfer...it actually is called a Text GRID and it doubled the file size. 
 I haven't tried using GIS to convert to TIN. I wonder if this is any better for file size? 
 Thank you, Matt

Hi Matt 
 See https://communities.bentley.com/products/geotechnical1/w/wiki/4067/how-to-import-an-esri-tin-into-gint-via-xyz-grid-file 
 gINT can import a grid file up to maximum size of 180 MB?? (I am struggling to recall) So you could make a checkerboard of grid files from one bigger grid using the Datgel Grid File Pre-processing Tool , which is part of the DGD Tool. The fully functional trial works for 14 days.
