LandXML cross section roads

To use a LandXML cross section road file in Origin Roads, you must select the LandXML cross section road file to use and then redefine it as an RXL road file.

Add the LandXML road from the menu

1. In Origin Roads, tap and select Define.

2. Tap LandXML road.
3. Select the LandXML file. The file must be in the Origin project folder on the controller.

4. Tap Next.

   The New road screen appears. To continue, see Redefine the road as an RXL road below.

Add the LandXML road from the map

1. In Origin Roads, tap in the Map toolbar to open the Layer manager and select the Map files tab.

2. Tap Add and then select the LandXML cross section road file from the Origin project folder on the controller, or from Trimble Connect if the project you are working in is a cloud project. Tap Accept.

   By default, the file you have linked to the job is visible in the map, indicated by the check mark next to the file name .

3. To make items in the file selectable, tap the file name in the Map files tab. A check mark inside a square indicates items in the file are selectable.

4. To close the Layer manager, tap Accept.

5. From the map, tap the alignment to select it and then tap Define to define a new LandXML road.

   The New road screen appears. To continue, see Redefine the road as an RXL road below.

1. Select the horizontal alignment, the profile alignment, and the surface that will define the road.
2. If the elevations defining the cross sections are:
   • absolute, select the Absolute design cross‑section elevations check box to ensure the templates are resolved correctly.
   • relative to the alignment, clear the Absolute design cross‑section elevations check box to ensure the templates are resolved correctly.

   For more information, see Cross section elevations.

3. The LandXML format does not support side slopes, but you can add these as follows:
   • If the last point in the cross section represents a side slope, select the Set last cross section point as side slope option to convert this point to a side slope. The slope value from the second last point to the last point is then used to define the side slope.
   • If the last point in each cross section represents a side slope hinge position, select the Add side slope to last point in cross section option and complete the fields to add cut and fill side slope values, including a cut ditch to this point. A side slope can be defined for both the left and right sides of the cross section.
4. Select the road cross section interpolation method. Select either:
   • Elevation
   • Cross slope

   For more information, see String interpolation.

   For Interpolation by elevation and Interpolation by cross slope examples, see Template positioning examples.

5. When selecting a LandXML file created from 12d Model where the transition type is cubic you will be prompted to select the applicable cubic type. This is because the cubic type is not identifiable in the file. Select either:
   • Cubic spiral
   • NSW cubic parabola

6. To save the edited road as an RXL road file, tap Store.

   The software returns to the map where the new road is selected, ready to review or stake.

Once the road has been converted to an RXL road, you can edit the road definition as you can for an RXL road. For example, you can add additional points or strings.

To edit the road definition, tap Define and select a component to edit. See Define an RXL road.

To review the road definition, tap Review. See Review the road design.

To stake out strings or stations that define the road, see Stake the road.
