Measurement - Control Distance

The Control Distance tab displays distances that have been measured between two points.

Requirements: Either the start or the end point must be part of the current calculation project. One of the points must be either new planimetry points, or new moveable detail points, including GPS points. You cannot control points that are stored in other industry models.

To enter the measurements, do one of the following.

• Enter the values manually in the Measurement data grid. In AutoCAD Map 3D, you can select the points in the map. See also Processing Control Distance Measurements.
• Import control distance measurement files. See Importing Control Distance Files.

Control Distance tab	Description
Fault Section (FS) Threshold	Specifies the fault section FS that must not be exceeded. FS is the difference between the calculated distance, and the measured distance.
Operator	Selects the operator.
Detail Points area	To exclude or include detail points from the adjustment calculation. These commands can also be started for the whole calculation project. See also Detail Points Configuration
Activate All	Includes all detail points of the selected session by setting the Active attribute in the Measurement Data tab.
Deactivate All	Excludes all detail points of the selected session by clearing the Active attribute in the Measurement Data tab.
Add From Map	Adds the points from the map. Click the button, and select the points in the drawing.
Save	Saves the modifications.

The Add From Map command is not activated. To use this command, generate graphic. We recommend, that you use a display model that has a project filter (FID_PROJECT) to only display the points of the selected calculation project.

Tip:

Using Add From Map you can also select a line feature in the map. Then, the start point, or end point next to where you clicked, will be selected.

The measurement is displayed on two tabs, Measure Data tab, and Results tab.

Measure Data Tab

Measure Data tab	Description
From Ident.	Displays the identifier of the first point.
FC	Displays the field code.
To Ident.	Displays the identifier of the second point.
FC	Displays the field code.
Active	Specifies whether the measurement is used in the calculation. Clear this option to exclude the measurement.
Distance	Specifies the distance that has been measured.

Results Tab

The Results tab displays the residuals and indicators for each observation.

Results tab	Description
From Ident.	Displays the identifier of the start point.
FC	Displays the field code of the start point.
To Ident.	Displays the identifier of the end point.
FC	Displays the field code of the end point.
Fs	Displays the fault section FS.
Result	Displays an icon that indicates the result. Hover over the icon, and read the tooltip for more details. If one control distance controls two points, and if the result type is not the same, the worse result is shown. See also Control Distance Measurements.

A result is available for the start point, and for the endpoint. If the result type is not equal, the worse one is displayed in the UI.
