Vertical softkeys
The following contour elements are available for programming contours:
Straight line in the vertical direction (X direction)
Straight line in the horizontal direction (Z direction).
Oblique line in the X/Z direction. Enter the end point of the line using coordinates or an
angle.
Arc with any direction of rotation.
The "More" softkey in the basic plane of the contour programming accesses the "Pole"
subscreen and the "Close contour" softkey.
The pole can only be entered in absolute Cartesian coordinates. The "Pole" softkey is also
present in the starting point screen. This enables the pole to be entered at the start of a
contour, so that the first contour element can be entered in polar coordinates.
The contour is closed by a straight line between the last entered contour point and the
starting point.
By selecting the "Abort" softkey you can return to the main screen, without transferring the
last edited values to the system.
When you click the "Accept" softkey, you close the contour input screen and return to the
ASCII editor.
Horizontal softkeys
You can zoom in or out of the graphic with the first four horizontal softkeys (e.g. "Zoom+").
An element was selected using the cursor keys.
"Follow element" ("Follow Element") increases the screen section to the selected element.
When you select this softkey, you can move the red cross-hair with the cursor keys and
choose a picture detail to display. When you deactivate this softkey, the input focus is
positioned in the contour chain again.
If you press this softkey, help graphics are displayed in addition to the relevant parameter
(see screenshot below). Press the softkey again to exit help mode.
