I've unfortunately gotten a major cold, so I have not made the videos yet. But I can try to explain better... in the path tool you select whatever path you want, on the bottom right you have path options, you hit select grid, not youre going to go to whatever object or path you want to connect this larger path too and hover over until you see a blue 3x3 grid, once you see that left click (now youre in grid mode) and you now select any square on the grid to build a piece and your path will expand. There's an option for square edges if you prefer that. If this still didn't help, try adding me KingMario5, I'll try and show or teach you, but I just can't make a video at the moment until I'm better.
