Cross section: Construction line - modify

Parameters for construction lines can be modified. The definitions below are dependent on the type of constr. line. Not each described input is related to all types of construction lines.

Note: The cross section is recalculated if a parameter of a construction line is changed. The modification is accept only if the recalculation of thecross section was successful.
SettingDescription
Name

The name is given by the program automatically. It can not be changed.

Type

Each construction line has a certain type defined by its input. The type can not be modified.

Options "Extended to +/-infinity"

These options can also be found in the symbol column on the left side of the cross section window. The selected construction line can be extended to "+/- infinity". One of the options must be set, otherwise the construction line could not be selected. Exceptions: Lines defined by intersections and polygons.

edit box "Variable"

The distance or the angle defining the position of the line can be combined with a cross section variable. A variable makes a construction line able to be positioned.

Note: If "None" is selected, the edit box for the distance or angle is available for a input.A constant value is assigned to each variable. A table or formula may replace this assigned value later when defining the segment points.
edit box "Distance" / "Angle"

A constr. line is defined relative to another line either by an angle or a distance. This value is unit dependent.

Note: The value can only be changed, if no variable is selected in the variable edit box.
Option "right" / "left"

Each construction line defined by a parallel movement can by mirrored about its basic line.

Dependencies

Each construction line is dependent on other construction lines.

Note: The dependencies cannot be modified presently.
Predecessor/Successor

The definitions for polygons can be checked using these buttons. The current part of the polygon is marked by an arrow symbol in the graphic window.

edit box "Extended"

A further window appears offering the selection of pen and line types for the construction line.
