Steps

1. Drafting:

   1. Draft Terrain Ramps in the Site Plan inside the plot.
   2. Draft Ramp Landings inside the Terrain Ramp at all locations where the terrain ramp provides access to the basements.
   3. Make sure that the centerline of the Terrain intersects the Ramp Landing at exactly two points.

2. Marking:

   1. Open Guided Marking and navigate to the Terrain Ramp node.
   2. For each Terrain Ramp, provide the following data:
      1. Ramp Structure Type (Select TERRAIN)
      2. Ramp Usage Type: (Select VEHICULAR)
      3. Ramp start elevation from ground level (Enter value in meters. Add "-" sign for values below ground level)
      4. Ramp end elevation from ground level (Enter value in meters. Add "-" sign for values below ground level)
   3. For each Ramp Landing, provide the value for "Ramp Landing Elevation From Ground Level" (Enter value in meters. Add "-" sign for values below ground level).

Checkpoints

1. The start elevation must be always more that the end elevation of the Terrain ramp. That is, a terrain ramp can slope only downwards from the start point to end point.
2. A Ramp Landing must be proposed at the location where the terrain ramp provides the entrance to the basement.
3. The elevation of the Ramp Landing from ground level must always fall between the start elevation and the end elevation of the terrain ramp.
4. The centerline of the Terrain Ramp must intersect the Ramp Landing at exactly two points.
5. Travelling downwards from the start point to end point on a terrain ramp, elevation from ground level of each ramp landing in order must decrease. No two ramp landings on a terrain ramp can have the same elevation.
6. The Terrain Ramp is considered to provide access only when the corresponding Ramp Landing coincides with a DriveWay or another Built Up Ramp within the Basement Floor Plan.
7. The minimum width of the Ramp Landing where it coincides with Driveway or another Ramp must be 3.6 m.
