Dialog box Dihedral Angle Component
db_ath_bar_bt_planang_edit
Dialog box section Graphics
In the display field angles are displayed symbolically which facilitate a visual control of the defined dihedral angles. The active definition can be seen on the base point of the definition axis.
Dialog box section Display
You can change the preview display with the option buttons Complete, Cutting and Simple:
• Full: Complete depiction of the assembly
• Cutting: Shows the cutting outlines or outer outlines
• Simple: Shows the enclosing rectangles
Dialog box section Info
Via the dialog box section for dihedral angle there is an info section in which, if it has been issued, the name of the component with its item number and the material are displayed.
Dialog box section Dihedral angle
Here the display of the dihedral angle defined on the component is made.
The specification of the dihedral angle and of the variable range on the component is a mandatory requirement for the execution of the function.
Dialog box section Direction of rotation
Here, the direction of rotation of the dihedral angle to be defined can be specified. Also here, the change can be visually checked in the display.
The direction of rotation depends on the defined variable range. This means that:
For a component which in the initial state has a defined dihedral angle of 180° and a variable range from min. 90° to max. 180°, the specification of a negative value causes a rotation in the mathematically negative direction of rotation.
Dialog box section Definition axis
In this section you define the points for the ranges affected by the dihedral angle.
Dialog box section Center of rotation
Here, the center of rotation of the definition axis can be specified relatively or with polar values. The dimensions entered here describe the initial point of the definition axis relative to the base point of the component. This point must be selected such that it lies outside of the component outline and the perpendicular to the bending plane passes through the bending point.
Practicably, the required dimensions on the component should be accessed from the drawing prior to the definition.
Dialog box section Reference point
The reference point forms the bending axis starting from the point of rotation of the definition axis relative to the bending plane of the component. With many profile systems the bending plane lies at the level of the glass support without gasket. The base point of the assembly is determined anew from the reference point depending on the dihedral angle of the assembly, so that the assembly is correctly positioned. Here too the dimensions can be specified with relative or polar values. A symbolic angle is shown in the display for a visual check.
Dialog box section Reaction
Through the selection of the appropriate option button, you can determine the reaction of the function on the component.
Option Bend This option has the effect that the section of the component cut by the definition axis is bent depending on the dihedral angle.
Option Fold This option works similar to bending with the difference that it can only be used for ATHENA sheets. In addition, the central section of the sheet is stretched during folding in dependence of the dihedral angle.
Option Cut This option causes sections of the component which would be overlapped by changes to the dihedral angle to be cut at the definition axis, e.g. with insulation.
Tick box Bending axis perpendicular This tick box must be activated if the line between the center of rotation and the reference point does not cut the component outline, but rather the bending axis (the intersection line through the component outline) is located perpendicular to it. The bending axis is displayed as a symbol for a visual control.
The effect of the definition can be checked with the button Test.
You terminate the function with OK, all entries are discarded with Cancel and ? calls the online help.
