Traverse Curve
To calculate the parameters of a traverse curve when the traverse point and direction and the curve radius and length parameters are given:
Click to show / hide the illustration of curve parameters used in MAGNET Field
- In the Input tab, specify the traverse point and direction, curve radius and length parameters:
- In the Results tab, review the results of the calculation and click
to save the data to a *.txt file, if required:
- PT Point is the name of the calculated point of tangent, the end point of the curve. To add the calculated PT point to the job, ensure the check box near the calculated point is checked
, then click
.
- Coordinates of calculated PT point.
- PC Point is the name of the traverse point, the start point of the traverse curve.
- Radius of the curve.
- Length of the curve.
- Chord is the distance between the start and end points (tangent points) of the curve.
- Curve angle defines the angle in degrees which is used to compute the radius of curve with the length of 100 units.
- Chord angle defines the angle in degrees which is used to compute the radius of curve whose chord is 100 units long.
- Delta is the internal angle from center to tangent points.
- Tangent is the distance between the point of intersection of the tangents at the starting and ending points, and the ending point.
- External is the shortest distance between the point of intersection and the curve (along the line joining the point of intersection to the radius point).
- Mid Ord is the length of the line segment between the curve and the chord on the line joining the point of intersection to the radius point.
- Segment is the area of a circle bounded by a chord and the circular curve that it cuts off.
- Sector is the area of a circle bounded by two radii and the circular curve they determine.
- Fillet is the area between the circular curve and the two tangents at the start and end points of the curve.
- Start Azimuth (Start Bearing) is the direction of the tangent at the start point of the curve.
- The Map tab shows the job's objects with the illustration for the results and supports generation of a field report with the results of calculation (use the Create Field Report command from the context menu).
- The Drawing tab shows the illustration for the results and supports generation of a field report with the results of calculation (use the Create Field Report command from the context menu).
