Linework Station & Offsets
To define parameters for staking offset locations. The Station / Real-Time / Skew Station button allows you to toggle between staking known and unknown staking locations:
- For Station:
- Select Station (3D Station if the Start 3D mode is chosen for the stakeout) to set the current or start station. The two arrow buttons allow you to decrease or increase the station by the interval specified in the station Interval shown.
- Set the station Interval.
- The Num Segments field shows the number of segments of the line determined with the given station Interval. Entering the number of segments recalculates the station Interval to match this number.
- Enter the Right Offset or Left Offset of the computed point with respect to the line at the stations.
- Enter the Up Offset or Down Offset height offset, or the vertical Grade Offset (in percentage) with respect to the height of the line at the station. If the grade is falling, the value should be negative.
- In Angle Pts, select how the angle points will be computed at segment intersections:
- Offset Bk: The offset point at the intersection will be computed from the end point of the first segment.
- Offset Ahd: The offset point at the intersection will be computed from the start point of the second segment.
- Bisector: The offset point at the intersection will be computed from the intersection of the offset of the first and second segment.
- In Curve Pts, select how points on curve segments will be selected:
- StationOnly: The offset points on curve segments will be computed at intervals along the curve.
- RP: Only the curve radius point will be computed.
- PI: Only the curve point of intersection of tangents will be computed.
- MOC: Only the point in the middle of the curve will be computed.
- Click Stake to start the stakeout process for the designated offset locations. More...
- For Real Time:
- Enter the Right Offset or Left Offset of the computed point with respect to the line at the stations.
- Enter the Up Offset or Down Offset height offset, or the vertical Grade Offset (in percentage) with respect to the height of the line at the station. If the grade is falling, the value should be negative.
- Click Stake to start the stakeout process for the designated offset locations. More...
- For Skew Station:
- Select Skew Station to set the current station as start station of the new line. Enter the corresponding station.
- Enter the Left Skew or Right Skew value as the start angle in the horizontal plane (relative to the existing line) of the new line.
- Enter the Skew Offset to set a point on the new line.
- Enter the Up Offset or Down Offset height offset, or the vertical Grade Offset (in percentage) with respect to the height of the skew station. If the grade is falling, the value should be negative.
- Click Stake to start the stakeout process for the designated offset locations. More...
