3D-orthogonal calculation

Three dimensional AB-calculation. Select first two points (P1 and P2) for the reference line. Then you can either select other points and get the calculated values in dialog and result file, or type in values in the dialog and get new coordinates.

General principles how the calculations work are explained under Calculation functions.

Fields

Upper part fields display object type and three freely selectable attributes.

Pages

XYZ Data All

Values

List of all calculation parameters and their current values.

Sort

Restores original parameter order.

Up, Down

Moves parameter up or down in the list. Works also with arrow keys with the Alt-key.

Save

Saves the current point. With the Alt-key modifies active point instead of adding new point.

Locked

Locks code fields. Pointing points with mouse gets then only coordinates. Locked codes are saved at exit and restored when function is started.

Code

Activates the data copying from another object. The other object containing data is pointed by the mouse. By default only the object code is copied. With the Shift-key all attributes are copied. With the Ctrl-key only text is copied.

Control

Saves difference values as control attributes to original points. Control arrows are then drawn according the control measurement settings.

Attribute

When the checkbox is selected, calculation results are stored to both selected and created points as attributes. Calculation result attribute names can be found from the calculation parameter list.

From model

You’ll get the intersection point of the reference line and the model. Dialog values will be updated. In case of several intersection points, the one closest to point P1 is selected.

Point 1, Point 2

You can change the reference line by pressing the button Point 1 and then using mouse to select new start and end points. If you press the button Point 2, you can change only the end point.

Terrain model

Select the model to be used in calculation.

Mode, X

Displays current edit mode (move, rotate, add, etc.). The X button quits the mode and returns to the normal state.

CheckDuplicate special setting in Settings/Start Program defines whether active file is checked for duplicate points.

Special settings

There are some special settings related to this function.

EditFlag

Settings affecting edit and calculation function behavior.

TopDataList

Defines which attributes are displayed first in the list. By default T1,T2,T3,T4,T5.
