For an automatic primary design of the contours the following values are used:

▪Dimensions: dH, dS, d2, b1, b2

▪Radius of the circle segment R: 14% of dS

The manipulation of the contours can be achieved by shifting the positions of the points. As an alternative the position of points can be realized by input of numerical values.

By the context menu item "Straight line", the curve can be converted into a simple line.
