So i created two curves and i saw 'intersect' and snapped to it.
After that i saw an error message about 'to join, you must select two open endpoints' when i was trying to join the two lines using ctrl-shift-alt-j (IDK what this is but it's part of tutorial).
Upon closer inspection and zooming 6400% i noticed the two path ending anchors aren't connected and i can't drag them onto each other to connect.
Why did this happen and why won't my path ending anchor points connect..?
