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.
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.
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.
