Import Alignment from a Land XML File
Before Importing a LandXML File
Since LandXML files may contain a geographic coordinate system (GCS) that defines the roadway alignment, it’s essential to take several steps before importing the LandXML file to ensure precise bridge generation. This is especially important if a federated model is being created.
...
Prior to importing a LandXML file, set the Geographic Coordinate System to the project
...
Once the steps above are completed, users can now import the LandXML file.

Please follow the instructions provided below to import an alignment in XML file format. |
1 | Example XML files to experience the steps from 1 to 17. | Example XML file :
| |||||||||||
2 | Click on the file at step 1 named ‘ExampleAlignment2.xml’. Then, click on the download icon located in the top-right side of the screen. |   | |||||||||||
3 | Click on the three dots located in the top left corner of the screen, just to the left of the project name, and then select 'Import'. |  | |||||||||||
4 | There is an alternate way to import an alignment: Click on 'DATA' located in the bottom-middle section of the screen. You will see that a spreadsheet opens.
|   | |||||||||||
5 | Click on 'Bridge Alignment' under 'Roadway Alignment' in the workflow. You can view all the alignments available in the project in the spreadsheet. |  | |||||||||||
6 | Click on the cell that displays 'ALIGMENT1'. When you click on the cell, you will see three dots appear to the right of the cell. Click on the three dots that appear on the right side of the cell. Then, click on the ‘Import LandXML’ |  | |||||||||||
7 | In the opened window, select the XML file you want to import. You can select only one XML file at a time. In Step 1, the 'ExampleAlignment2.xml' file has been attached for you to experience the import process. |  | |||||||||||
8 | After the import process, you will see a pop-up message on the project screen indicating the result of the import. Click on 'Close' to view the imported alignment. |  | |||||||||||
9 | As seen, the imported alignment was drawn in a different route. The current bridge has previously been set to 'ALIGNMENT 1'. |  | |||||||||||
10 | To set the current bridge to the newly imported 'ALIGNMENT 2', click on 'DATA' located in the bottom-middle section of the screen. You will see that a spreadsheet opens.
On the left side of the spreadsheet, you will also find the workflow. |   | |||||||||||
11 | You can view all the alignments present in the project by clicking on 'Bridge Alignment' under 'Bridge Geometry' in the workflow. |  | |||||||||||
12 | To change the alignment of the bridge, click on 'Bridge Alignment' under 'Bridge Geometry' in the workflow. As seen, 'Alignment 1' has been set for the 'BRG1' bridge. |  | |||||||||||
13 | Click on the cell that displays 'ALIGMENT1'. When you click on the cell, you will see three dots appear to the right of the cell. |  | |||||||||||
14 | Click on the three dots that appear on the right side of the cell. At the bottom of the opened panel, you will see options such as 'Set to None', 'Set to ALIGNMENT1', and 'Set to ALIGNMENT2'. Click on 'Set to ALIGNMENT2' to set it as the alignment. |
| |||||||||||
15 | As seen, the 'BRG1' bridge is now set to 'ALIGNMENT2'. |  | |||||||||||

After importing the LandXML file,
Users have two options:
Users can either use the alignment's Latitude and Longitude data as the Project Local Origin.
...
2.Alternatively, they can use the Project Origin's latitude and longitude data for the alignment's latitude and longitude.
...
The option of Set Project Local Origin to Alignment Latitude and Longitude is strongly recommended if the goal is to generate a federated model. This ensures that all related projects have the same local project origin, which is crucial for the model to be as precise as possible.
