When you have created a new contour and specified the start point,
you can define the individual elements that the contour comprises.
The following contour elements are available for the definition of a
contour:

Straight vertical line

Straight horizontal line

Diagonal line

Circle / arc
For each contour element, you must parameterize a separate screen
form. Parameter entry is supported by various "help displays" that
explain the parameters.
If you leave certain fields blank, ShopTurn assumes that the values
are unknown and attempts to calculate them from other parameters.
Conflicts may result if you enter more parameters than are absolutely
necessary for a contour. In such a case, try entering less parameters
and allowing ShopTurn to calculate as many parameters as possible.
As the transition element between two contour elements, you can
select a radius or a chamfer or, in the case of linear contour elements,
an undercut. The transition is always appended to the end of a
contour element. The contour transition is selected in the
parameterization screen form of the contour element.
You can use a contour transition element whenever there is an
intersection between two successive elements which can be
calculated from input values. Otherwise you must use the
"Straight/Circle" contour elements.
The contour end is an exception. Although there is no interface to
another element, you can still define a radius or a chamfer as a
transition element to the blank.
