In the first screenshot shows the result while I am holding the window of the original view (the blue line). The original Perspectiveview, that has been resized twice, trough the sample workflow showed in the second screenshot. The first result is good. The second give the awkard result to change the target of the view in the opposite direction. Trying different times with different values that happens all the time, inserting the integers 2, 3 and so on will always invert the direction of the view… I thought I could apply something like this to all my 2000 views…still looking for!
