Fields

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

Pages

Line-line Line-arc Arc-arc Data

X, Y, Z

Calculated coordinates.

Z1, Z2, Z, dZ

Z1 takes height from the first calculation object and Z2 from the second calculation object. Third option uses average of heights. Field dZ shows the height difference between elements.

Point 1, Point 2

Result point selection.

Line, Rotation, Offset

Rotation and offset parameters for line. Rotation is always applied before side offset.

Arc, Radius

Arc pointing method is selected from the list. Radius field displays arc radius.

Copy XY

Copies coordinates to the clipboard as a comma separated text. By default copies only X and Y. With the Shift-key the Z is also copied.

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 including the line number. New points are then added to that line.

Line, Arc
