A contour always has to be closed. If you do not wish to create all
contour elements from starting point to starting point, you can close
the contour from the current position to the starting point.
Press the "Close contour" softkey.
ShopTurn inserts a straight line between your current position and the
starting point.
When you have created all contour elements, you can still define a
transition element to the blank at the end of the contour before you
transfer the contour to the process plan.
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" softkey.
Place the cursor on the contour end
Press the "Cursor Right" key.
The associated input screen form opens.
Wählen Sie die gewünschte Lage des Übergangselementes an.
Press the "Accept" softkey.
A transition element to the blank is added at the end of the contour.
