To toggle the roadside grading method

Users can specify whether to use a Fixed Slope or Fixed Width grading method to determine how a road's roadside cross-slope is graded.

1. Select a design road to display its asset card.
2. On the asset card, change the edit mode to Roadside Grading.
   
3. Toggle Grading Method between Fixed Slope and Fixed Width. The model reflects your choice immediately.
   Note: With fixed-slope parametric grading, the cut slope and fill slope are fixed up to the grading limit you set on the asset card; slopes that don't reach extant ground are tied in with a near-vertical surface. With fixed width, the grading varies the slope over a fixed distance (based on the road style) with a smooth tie-in to extant ground.
