# 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.
