Pier foundations possess one parameter considered for defining its top.
| Parameter Description | Content Parameter | Parametric Value | InfraWorks Set/Read | Inventor | Revit |
|---|---|---|---|---|---|
| Match by surface to pier | MatchBySurfaceToPier | Defines how the top of a foundation is determined. The bottom of the pier is vertically aligned with the top of foundation. Either True or False. | Yes/No | No | Yes |
Pier foundation origins are defined by lateral, longitudinal, and vertical dimensions.
Lateral and Longitudinal Dimensions. A pier foundation origin is placed directly under the origin of its pier.
Vertical Dimension. When MatchBySurfaceToPier is set to False, the origin must be at the top of the foundation.
When MatchBySurfaceToPier is set to True, the origin can be at any elevation. The top of the foundation is then considered to be the top of the bounding box of the foundation. This is the more accurate but slower option. A true match by surface, between foundation and pier, is not performed. The foundation and pier may not touch if the pier bottom or foundation top are not both horizontal. However, the BottomVerticalOffset parameter of the pier can adjust this.
