# Convert 3D strings to side slopes

For LandXML string roads, the outermost strings to the left and right of the centerline define a side slope. To use them as side slope strings in Trimble Access Roads you must convert the 3D strings to side slope strings.

1. In the map, tap the LandXML string road to select it and then tap Edit.

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.
