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?
For more Details: left is the sample file from Bentley and right is my XML file with every alignment station point in X/Y/Z when I'm importing it. nothing happens.
Thanks Steve Willoughby for the Info. I know LandXML but it depends on the textformat inside the XML. I got a cgPoint-XML which can be imported by OTD but only as points so "Add Tunnel Corridor" would not select the points since its not a alignment. So my aim was to get a LandXML with my points as a Alignment-LandXML.
So what I did: I imported a X/Y/Z-Point-CSVfile into 3rd party software -> Made a 3D Polyline out of the points -> converted the 3D Polyline to a Alignment -> Exported it to LandXML in 3rd party software.
Everything fits now. Its a long workaround but the only way for me right now. The Alignement contains over 20.000 single points and is more than 10km long.
