Foundation Plan CADD [SPIG]

The Foundation Plan CADD workflow item generates a CAD plan drawing of the bridge foundation layout. The plan shows the footings, piles, abutments, columns, and end bents in plan view — along with support-line stations, footing elevations, and PGL labels — and can be exported to DGN/DWG. Visibility and annotation sizes are controlled by the parameters below.

General

Bridge: Pick the Bridge Alignment for which the foundation plan is generated. All support lines, abutments, columns, and foundations are read from this bridge.

Start/end PGL #ft from before/after bridge [Use Alignment Start and End Station]: Distance in front of the first support line and behind the last support line at which the plotted PGL (profile grade line) starts/ends. Leave the default of -1 to use the full alignment start and end stations.

Detailing

Dimension Line Font Size (Only .dgn): Text height used for dimension-line labels in the CAD output; only used when exporting to DGN.

Annotation Font Size: Text height used for all annotation text (non-dimension labels) in the CAD output.

Annotation Arrow Size: Arrow head size used on annotation leaders.

Number of Decimal Points: Number of decimals shown on numeric annotations such as stations and elevations (default 2).

Found. Elevation Box X Offset (CAD): X offset of the foundation-elevation annotation box from its anchor point in CAD units.

Found. Elevation Box Y Offset (CAD): Y offset of the foundation-elevation annotation box from its anchor point in CAD units.

Sup.Line Station Box X Offset (CAD): X offset of the support-line station annotation box from its anchor point in CAD units.

Sup.Line Station Box Y Offset (CAD): Y offset of the support-line station annotation box from its anchor point in CAD units.

Foundation Centerline - Dimension Line Offset: Perpendicular offset between the foundation centerline and its plotted dimension line.

PGL Name Box Station: Station along the PGL at which the alignment-name label box is placed. Defaults to an auto-computed station 240 ft ahead of the first support line.

PGL Name Box X Offset (CAD): X offset of the PGL-name box from the PGL Name Box Station in CAD units.

PGL Name Box Y Offset (CAD): Y offset of the PGL-name box from the PGL Name Box Station in CAD units.

Display Settings

Detailing

Display Station Markers [Yes/No]: When Yes (default), plots tick marks along the PGL at regular stations. When No, the remaining station-marker parameters below are hidden.

Station mark every #nth station: Spacing between successive big station marks along the PGL. Only enabled when Display Station Markers is Yes.

# of pieces btw. station marks: Number of equal segments between each pair of big station marks, producing smaller tick marks at the subdivisions. Only enabled when Display Station Markers is Yes.

Big mark length: Length of the big (primary) station tick marks. Only enabled when Display Station Markers is Yes.

Small mark length: Length of the small (subdivision) station tick marks. Only enabled when Display Station Markers is Yes.

Pile Reference Line Length: Length of the reference line drawn through each pile in plan. Only enabled when any of the pile display toggles (abutment footing, column footing, abutment, end bent) is Yes.

Pile Battered Angle Arrow Line Length: Length of the arrow line used to indicate the battered direction of a battered pile. Only enabled when any of the pile display toggles is Yes.

Abutment Display

Display Abutment Footing Pile [Yes/No]: When Yes (default), plots the piles of the abutment footing.

Display Abutment Pile [Yes/No]: When Yes (default), plots the piles directly under the abutment back/front walls.

Column Display

Display Columns [Yes/No]: When Yes (default), plots the column outlines in plan.

Display Column Footing Pile [Yes/No]: When Yes, plots the piles of the column footing. Default No.

End Bent Display

Display End Bent [Yes/No]: When Yes (default), plots the end bent outlines in plan.

Display End Bent Pile [Yes/No]: When Yes (default), plots the piles under the end bent.
