Line crossings should be minimized in Simulink models (due to MAAB/MISRA recommendations). Unfortunately, sometimes this cannot be completely achieved.
This script updates regular line crossings with a "line step" and improves a readability of the Simulink model ("3D like effect").
It uses the fact that default Simulink grid is 5 pixels - the script appends line steps of 4 pixels height, which can be easily identified and removed (undo function).
For usage see examples and m-file code.
A Matlab shortcut can be created to ease the usage.
