Slope-based Abutment Parameters

The Slope-based parameters are more intuitive than Offset-based parameters. They have angle dimensions to directly specify lateral slopes. When designing new parts for abutments it is recommended to use slope-based parameters.

For slope-based parameters, positive values specify a downward slope away from the alignment.

Parameter Description Content Parameter Parametric Value InfraWorks Set/Read Inventor Revit
Ballast wall left slope BallastWallLeftSlope The slope angle of the left side of the ballast wall. No/Yes No No
Ballast wall right slope BallastWallRightSlope The slope angle of the right side of the ballast wall. No/Yes No No
Seat left slope SeatLeftSlope The slope angle of the left side of the abutment seat. This slope is affected by the MatchSeatToBallastWallSlopes parameter. No/Yes No No
Seat right slope SeatRightSlope The slope angle of the left side of the abutment seat. This slope is affected by the MatchSeatToBallastWallSlopes parameter. No/Yes No No
Match seat to ballast wall slopes MatchSeatToBallastWallSlopes If True, the seat slopes will match the corresponding ballast wall slopes leaving the ballast wall height constant from the left to right side of the abutment. If false, the seat slopes are independently set to provide the best fit between the seat and the bearings, minimizing the required stretching of the bearings to fit them to the seat. Yes/No No Yes
