Define corridor slope patterns for cut and fill conditions in Civil 3D

When adding corridor slope patterns to a road corridor, you may notice that the slope patterns cross the channels running alongside the road in cut conditions:

To resolve this issue, ensure you use the correct point codes for daylight points in both cut and fill conditions. If you are working with the iDAS Civil 3D template, the appropriate point codes are already included in the Corridor Code Set Style:

• Cut condition Daylight,Daylight_Cut
  

• Fill condition Daylight,Daylight_Fill

For the corridor slope pattern definition, ensure that the correct point codes are assigned for both cut and fill conditions. In the image below, SBP refers to the Shoulder Break Point, and P2 represents the channel flow line:

The result with the correct slope patterns in cut condition:

If you use separate slope patterns for cut and fill conditions, you may consider assigning different colours to each to improve visual distinction. You can do this by duplicating the existing style and adjusting the component colour in the copy:

Assign the new style to the slope pattern definition for fill condition:

The result, which shows a different slope pattern colour in cut and fill conditions:
