In the following a function is described, which makes this possible. Below the
2D-graphic you find a button 'Shift ZP'.
Click this button to open a new window.
With the Up/Down-buttons you can shift the airplane as a whole around its
zero-point with mouse clicks.
There is a pair of buttons for each axis (X,Y,Z).
A click on the right mouse button pops up a menu to set the increment between
0.001m and 1m.
The two following pictures illustrate this function.
In the first picture the position of the zero-point is located in front of the
leading edge of lower wing.
The second picture shows a zero-point which was shifted in the X- and Z-axis.
It now lies between both wings.
