Hi Dmitry,
We are finding some problems in 3D that we are trying to solve but in 2D it seems to work fine:

public void doMarks()

This problem is for 2d too.
What will i do with this code?

Hi Dmitry,
Here you have a simple example of how you could move the marks. As you'll see, when this application is started, some marks overlap the others but clicking the button we calculate new positions moving them more to the right-bottom until there is enough space to draw them:
