To convert 3D strings to side slopes

For some LandXML cross section roads and LandXML string roads, the outermost strings to the left and right of the centerline define a side slope.

LandXML cross section roads

The LandXML cross section 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.

LandXML string roads

To convert 3D strings to side slope strings:

1. In the map, tap the LandXML string road to select it and then tap Edit. Alternatively, tap and select Define / LandXML road, select the road to edit and then tap Next.

   If the road you want to edit is not shown in the map, tap in the map toolbar to open the Layer manager and select the Map files tab. Select the file and then make the appropriate layer(s) visible and selectable. The file must be in the current project folder.

2. Tap Side slopes.

   The software lists any strings that are the outermost string at some point along the road.

   A string listed in red text indicates the string goes back on itself and it should not be used with the road. Use the Exclude option to exclude the string from the road.

3. Tap the strings to convert, or tap All. The selected side slope strings are colored blue in the map.
4. Tap Accept.

If required, you can convert the side slope strings back to 3D strings. To do this, repeat the steps above and tap the strings to convert, or tap None.
