If you want to change an existing dialog selection, you must select the
contour element in which the dialog was originally chosen. Both
alternatives are displayed again when you select softkey "Change
selection".
You can select another dialog.
If the selection has become unnecessary as a result of other input
values, you will no longer be requested to select a dialog!
A transition element can be used whenever there is a point of
intersection between two neighboring elements which can be
calculated from the input values.
You can choose among Radius R, a chamfer FS, and an undercut
(thread, thread DIN, Form E, or Form F) as a transition element
between any two contour elements. The transition is always
appended to the end of a contour element. You select transition
elements in the parameter input screen form for the relevant contour
element.
Place the cursor on the last contour element.
Press the "Cursor Right" key.
The associated input screen form opens.
Enter a transition element.
Press the "Accept element" softkey.
When you select "Abort", the contour element values are discarded
and you return to the basic display. The input focus switches back to
the contour chain.
The values of the parameter are deleted.
Select the contour.
Press the "Cursor Right" key.
The individual contour elements are listed.
Place the cursor on the contour element to be deleted.
OK
Press the "Delete element" softkey and confirm with "OK".
The contour element is deleted.
To save the contour, press the "Accept" softkey.
If you have entered the available data for a contour element or
selected the desired contour by means of softkey "Select dialog",
select softkey "Accept element" to store the contour element and
return to the basic display.
You can then program the next contour element.
