Let me give two personal examples, and then I'll ask my question: 1) I was trying to correct the border of large park area but ran into a ton of problems because most of the points (nodes?) in that section were joined to that of a street, which was also joined together with the border of a jurisdiction. It wasn't possible to simply adjust the park boundary without incorrectly changing the street or the jurisdiction border too. I was able to accomplish my goal by using the scissors tool to unlink the items, which became very tricky to separate what I wanted but leave the other two joined. 2) I want to adjust the boundaries of an airport apron. Right now the apron encircles the entire airport terminal, which is kind of ridiculous since planes can't taxi through the gift shop. So I may opt to correct the shape to go loosely around the terminal, but another (more precise) method could be to retrace the entire airport terminal (building) border whereas I would join all those points (nodes?). That would be nice and precise but I really worry about the situation I described above, in that it would be a nightmare if for some reason anybody ever needed to separate the two. So my question is this: What is the recommended standard procedure for properly "drawing" two or more adjacent areas? Should they share the same points so they fit nice and snuggly, or should they remain independent (even if they are put one on top of another)? the nodes overlap)? Thanks.
