I'm completly new to OpenTunnel Designer. I use Leapfrog to model the ground and import it to OTD as IFC. The very first step is to import an alignment. I have the Tunnelalignment as an Excelsheet with X/Y/Z for each station.
As I found out the alignment can only imported as LandXML or manually. I also have the Alignment as JSON and tried to convert it to XML but once I import the XML nothing happens. Not even a Error or sth.
I lack the Information to create the Alignment manuelly since the Tool wants some angles for the direction of the alignment which I dont have. Only X/Y/Z Coordinates or the JSON.
My question is: How do you guys deal if u dont get an alignment from OpenRoads or other programms? What options do I have in my case?
I would recommend you define the alignment using tangents and curves, not as a series of points from the XYZ data. Here is a link to the OpenRoads wiki page complete with a Learning path for ORD Geometry, along with links to many videos detailing how to create alignments. OpenRoads Geometry
Thanks for the help, I'm still testing the OTD. So creating a fictitious alignment manually with tangents and curves helped to continue the progress. But on the long run I need to find a other solution since I'm getting the alignment from our surveyers in digital format as I described above. It needs some testings - will come back if I got more information
