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
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.
Hi,
Your xml file does not follow the rules that civil needs in order to correctly create the geometry.
Please have a look at this information
Import Geometry (bentley.com)
LandXML is a schema that is an industry standard that has been around for a little over 20 years now. Any civil engineering product should give you the ability to import and export this format. As Vlad points out, we can import LandXML, along with some ascii text file formats.
