SUMMARY The 5.0 beta two point perspective assistant is already very impressive, however something seems to be missing and it is a ruler that is parallel to the horizon (line connecting the two vanishing points). It would be useful for drawing stuff in open spaces where some areas would necessarily show the horizon without stuff obscuring it and also for drawing utems that are in front of camera and parallel to it, rotated on different angle.
Not sure if agree; it's only useful for some cases and it would make using the vanishing point more difficult. Maybe if it was disabled by default, though...
