what exactly is the problem? Are you having troubles extracting coordinates from curves in Grasshopper? Are you having troubles passing those coordinates to an external application? Are you trying to write a file with FEA data?
Trying to pass it through to an external application. I figured out a quick hack. using the Format function and streaming data to an excel spreadsheet, but I'd like the system to be a bit more robust.
Well, what options do you have to communicate with this other app? Does it have an SDK that can be accessed from an external process? Does it support scripting? Does it have a file format that can be easily written by another app?
I was at SG last time. I would have come again this time but Bentley doesn't like people from other companies to attend.
