Geopak TIN files are Bentley Proprietary Format and they dont share that with us. The choices you have from Bentley Products are
- LandXML
- iMODEL v1 (Select Series 3 and Higher of Bentley Products but not OpenRoads Designer that is releasing iModel 2.0 version soon)
- DGN Files for CAD type Data
- DWG Files for CAD Type Data
- Cross Sections in the form of a .XSR file from InRoads (not sure if Geopak can output those also?)
If you get the TIN files you really have to open them with Bentley Product and Export them or ask the Engineer for one of the above file types unfortunately.
