To stake a curve created by three design points with offsets in the horizontal and vertical directions.
To stake points along the curve formed by design points.

- Define the curve by three points. Enter these point names manually, or select from the map
or from the list
of job points:- In Point of Curve, define the starting point of the curve.
- In Point of Tangent, define the ending point of the curve.
- Select either the Curve Pt or the Radius Point . The dialog changes its appearance depending upon the selection. In the second case the distance between Radius Point and Point of Curve should be equal to the distance between Radius Point and Point of Tangent. The Radius Point, the Point of Curve, and Point of Tangent define two curves - one with delta less than or equal to 180 degrees (Small curve) and the other with delta greater than or equal to 180 degrees (Large curve). Select either Small or Large from the Curve drop-down list to indicate which of these two curves should be used.
- You can perform the stakeout process in the horizontal plane. To do this, set Start 2D. To stakeout a curve in the horizontal and vertical planes, set Start 3D.
- In the field next to the Start 2D / Start 3D button, you can set stakeout start station from the start point along the curve in the horizontal plane or 3D. Also the curve length is displayed for the selected mode.
- Select the Include Transition Point check box to include start and end points if they do not fall on a designated station.
- The Stake Report field shows the name of the current stake report if it is set. Click
to open the Stake Reports List dialog to select the desired report or add a new one.
- Click Next to proceed in the Station & Offsets dialog.
