Using the CAD viewer
To use the
CAD-Viewer
without touchscreen, you have
to use a mouse or touchpad. All operating modes and
functions as well as contours and machining positions
can only be selected with the mouse or touch pad.
The
CAD-Viewer
runs as a separate application on the third
desktop of the control. This enables you to use the screen
switchover key to switch between the machine operating modes,
the programming modes and the
CAD-Viewer
. This is particularly
useful if you want to add contours or machining positions to a
Klartext program by copy and paste using the clipboard.
If you are using a TNC 640 with touch control, you can
replace some keystrokes with hand-to-screen contact.
