Reference Category (Reference)

The reference category includes the following properties:

• Alignment(RefAlign, ObjectId) - Device reference alignment name
  Usually it is the street axis, or the project axis. With this axis, the Stake and Offset will be calculated, which are in the category of Location
• Profile (RefGrade, ObjectId) - Name of the grade profile that is associated with the reference axis
  This information will tell you if the device is in cut or fill in relation to the design axis, as it compares the elevation of the insertion of the device in relation to the elevation in this Profile
• Ignore Adjustment (IgnoreSurfAdj) - Ignore elevation adjustment based on surface
  Note: Buried devices must ignore the adjustment
  This is a required property
• Surface (RefSurf, ObjectId) - Informs the name of the surface from which the program will extract the elevation of the insertion point of the device. If not provided, the elevation must be entered manually and in this case, the superelevation will not affect the device.
  Note: The reference surface need not necessarily be the same as the excavation surface. There are situations where the excavation of the trench for laying the pipes is carried out in the natural terrain, before the final earthworks are carried out. In these cases, it is considered that the part "above" the natural ground to be leveled is paid in the main leveling, after the pipes are laid.
• Point Devices
  • Superelevation (SurfAdj, Double) - Tells how much the device is above or below the reference surface elevation. PVs and storm drains are normally at surface level, so this value will be zero
• Linear Devices
  • Upstream (StartSurfAdj, Double) - Reports how much the StartPoint is above or below the reference surface dimension. For surface devices (trenches, gutters, stairs).
    DER-SP recommends that it be 10 cm lower (as seen in typical designs for these elements).
    Pipes are buried, in this case this property will not be available if you set Ignore Juste (IgnoreSurfAdj) to true
  • Downstream Superelevation (EndSurfAdj, Double) - Reports how much the EndPoint is above or below the reference surface dimension. For surface devices (trenches, gutters, stairs).
    DER-SP recommends that it be 10 cm lower (as seen in typical designs for these elements).
    Pipes are buried, in this case this property will not be available if you set Ignore Juste (IgnoreSurfAdj) to true
• Longitudinal Devices
  • Superelevation (SurfAdj, Double) - Tells you how much the device is above or below the reference surface elevation. When the device is associated with a alignment/profile or featureline, the calculated device elevations on the axis are added to this value
