Here, you determine the computation values which ATHENA uses for developments of sheet metal sections in the selected material.
The specified values are each subtracted from the outer edges of the sheet limb.
ath_mat_sys_bend
Dimensions for calculating bending allowances
With an obtuse angle the intersection point of the sheet outer edges is measured. With an acute angle the outer point is used for the measurement.
ath_mat_sys_bend1
Measurement points: left obtuse angle, right acute angle
Dialog box Bending allowances for sheet metal
db_ath_mat_sys_bend
The active material (e.g. Al - aluminum) is shown above the section Folding tables.
Dialog box section Folding tables
db_ath_mat_sys_bend_kantung
Here you manage the folding tables and their assignment to the current material.
Name The list contains the tables which are assigned to the current material. You can select an existing table to modify it. To create a new table, enter a new name. With a right click a context menu with further editing options appears.
Release table Removes the assignment to the current material.
Tables Contains all available tables. You can select a table. With a right click you obtain further editing options.
Assign table Assigns the marked table to the active material.
Delete table Deletes the marked table. Tables assigned to a material cannot be deleted.
Labeling Defines the table label in various languages. You can choose a language and enter the text in the input line.
[...] Opens the Dialog box Label, where you can conveniently edit the designations for various languages. You will find further information in the Chapter Label.
Inner bending radius Defines to which inner bending radius the allowances apply.
Distance of crimped edge Defines the default value for the distance of the crimped edge to the sheet.
Mode Changes the angle display in the values table. You can choose between display of the bending angle (angle increasing from left to right) and included angle (angle decreasing from left to right).
Unit Defines the unit in the bending table. The allowance values are converted when you change the unit.
Dialog box section Compensation values
db_ath_mat_sys_bend_zuschlaege
Here you define the deductions for the current fold table.
Mark the row you want to edit with the mouse. When you click a marked cell, it is released for editing. You can then change the allowance value directly in the cell. With a right click a context menu with further editing options appears.
Append row Creates a copy of the marked row above the marked row and releases the cell Thickness for editing.
Insert row Creates a copy of the marked row at the end of the list and releases the cell Thickness for editing.
Remove row Removes the marked row from the table.
Save settings Saves the changes to the bending tables. If you do not save the changes and quit the dialog box with OK, the changes only apply for the drawing session.
The changes are saved in the file cpl_mat.dex.
Click OK to close the dialog box and to save the changes. Click Cancel to discard the changes. In both cases ATHENA returns to the starting dialog box.
