To display and edit parameters of the existing point or to add a new point.
The code string is a specifying parameter for a code that allows you to group points with one code into different lineworks or areas, depending on the used code type and the value of the code string. Usually, the code string value is a number of the object entered by the user. The code string separates one surveyed line / area from the next one. Start to measure first line and assign the code string "1" to stored points. When you want to measure another line, change the code string from "1" to "2" and continue storing points. These points will be considered in application as the second separated line and shown on the map accordingly. While surveying, you can extend previously measured linework / area by assigning the code and string of that linework / area to new stored points.
Also, the code string can be assigned manually to existing points with code of Line or Area type. When processing points, MAGNET Field will be able to create linework / area from points with a code that has one string, and not take into account points with the same code, but with a different string.
The control code is a special type of code that can be used together with the code of Line or Area type and the same code-string by MAGNET Field and other point-processing applications for the interpretation of the survey results. Up to two control codes can be specified for a point that will be used to form linework or area. Assign a code of the Line or Area type, add a code string to form a specific Linework or Area object, and use a control code to define the role of this point in this linework or area.
Control codes can be added to points with code of Line or Area type and code string right in survey. Also, a control code can be assigned manually to existing points with code of Line or Area type and code string. MAGNET Field will be able to create linework / area from these points based on the role defined in the control code.
The list of available control codes:
|
Line Point
Indicates the start of the line segment in the linework along the direction. This is the empty control code added by default to points with code of Line or Area type. |
|
Arc Start (AS) Indicates the start of an arc. Arc parameters are determined by the presence of additional points in the line. These points can create the line segment with the arc start point which will act as the tangent to the arc. |
|
Arc End (AE) Indicates the end of an arc. Arc parameters are determined by the presence of additional points in the line. These points can create the line segment with the arc end point which will act as the tangent to the arc. |
|
Circle Edge (CE) When this code is applied to the first point of a three-point linework, this point and next two points define the edge of the circle. |
|
Circle Radius (CR) When this code is applied to the first point of a two-point linework, it indicates the center of a circle. The second point will define the radius of the circle. |
|
Rectangle (R) When this control code is applied to the third point of a three-point linework, this results in the automatic creation of a fourth point of a parallelogram whose diagonal is specified by the first and the third point. |
|
Close (C) When this code is applied to a point, the linework is closed by the line segment connecting this point to the start point of the linework. |
|
Arc End & Start (AE,S) When this dual control code is applied to a point, it indicates the end of one arc and the start of another arc. |
|
Arc End & Close (AE,C) When this dual control code is applied to a point, it indicates the end of the arc and closes the linework by the line segment connecting this point to the start point of the linework. |
|
Arc End & Gap (AE,E) When this dual control code is applied to a point, it indicates the end of the arc and the start of the gap segment in the linework along the direction. |
|
Line Gap (E) Indicates the start of the gap segment in the linework along the direction. |
|
Custom selection
When the user entered a non-supported control code. This is possible if Allow Custom Control Codes check box is selected in the Settings tab of the Code Options dialog. In this case, MAGNET Field will not interpret this control code. |
Note: If only one point is between the arc start and end points, the arc is formed such that all the three points lie on the arc. If there are two, or more than two points, between the points with the AS and AE control codes, the points are all connected by straight line segments.
