Hi all,
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
I have had better experience using tins in .xml format for large surfaces, give that a try
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.
cheers
Phil

Get the most out of gINT with Datgel Tools.
Thanks, so it seems like I would have to use a landxml compatible software or autodesk, geopak for this approach.
Or maybe use this Python strategy to convert an ESRI TIN to a landxml format. http://www.knickknackcivil.com/tin2landxml.html
Thank you, I will see if I can get DGD trial to work. I have never tested it out before.I have a call Monday morning with some colleagues to discuss possibly adopting gINT solutions for data reporting for our California groundwater management work, particularly for conceptual models and basin settings discussions of basins here.
Thanks everyone for the responses.
As a follow up, Kirk has been helping me with my GRID data import. What we determined is that gINT can't handle very large Grid sizes (ASCII GRID, TIN, or LandXML, even if you try to store as a .gsf. I have had trouble with sizes around 25 MB. I have seen others load sizes as large as 45 MB.
Our work-around is to extract surface data along my baselines in GIS and export to gINT as alignments. In some cases I have 6 to 7 datasets, so I have to create alignments in multiples of 3 datasets, alignments only store 3 z values at a time. We then export FENCES with each alignment and then copy and paste to buffer our alignments into one final FENCE.
It's not ideal but it does work.
