Bend programming

The parameters of one bend are divided over 2 screen pages.

3.b

The bend number, product number and drawing number are displayed in the top row on the
screen, the function of the "softkeys" in the bottom row.

Function keys:

prev. bend

select previous bend

next bend

select next bend

show
library

Open a window with an overview of the tool library.
From here, a tool can be selected. Only available if the
program cursor is positioned on a tool.
