Retain Wall Tie To Ditch

C3D RetainWallTieToDitch — shoulder + wall + barrier + walk/fill tie to a ditch alignment

At a glance

KindSubassembly (composed into an assembly)
DomainRoad
Civil 3D equivalentRetainWallTieToDitch
Geometry38 points, 39 links, 7 shapes
Conditional geometry12 of the points are created inside a branch — which ones appear depends on the parameters and the target surface
Targets2 (surface / offset / elevation targets this subassembly can be linked to)

Parameters

Defaults are the metric values the palette inserts. Every parameter can be driven by an expression or a target.

ParameterTypeDefaultMeaning
Side+1 right of the baseline, −1 leftRight (+1)+1 Right / -1 Left
ShoulderWidthnumber (metres unless the description says otherwise)1.33Paved shoulder width (m)
SlopeDirectionnumber (metres unless the description says otherwise)00 = away from crown, 1 = towards crown

Pave1Depthnumber (metres unless the description says otherwise)0.025Pave 1 depth (m)
Pave2Depthnumber (metres unless the description says otherwise)0.025Pave 2 depth (m)
BaseDepthnumber (metres unless the description says otherwise)0.1Base depth (m)

FootingCovernumber (metres unless the description says otherwise)0.5Cover over the footing (m)
Keynumber (metres unless the description says otherwise)11 = shear key under the footing
UseBarriernumber (metres unless the description says otherwise)11 = barrier on the wall crest
WalkWidthnumber (metres unless the description says otherwise)1Walk behind the wall (m)
WalkSlopecross slope as a ratio (−0.02 = 2 % fall)0.25Walk slope (magnitude)
FillSlopecross slope as a ratio (−0.02 = 2 % fall)0.5Fill slope to the ditch (magnitude)
ToeWidthnumber (metres unless the description says otherwise)0.5Toe width at the ditch (m)
WallHeightnumber (metres unless the description says otherwise)0Total wall height; 0 = auto (FootingCover + 1.2 m)

Points

Point codes are what feature lines, styles and quantity take-off match on — they are the contract this subassembly publishes.
