I'm building a part from a block in an assembly sketch, and something I've done has caused the part to become misaligned with the block it's been projected from. Any clues on what caused this and how to fix it? I think that the trigger here was that I added a constraint that resulted in a conflict. Still, there should be a way to fix it, or else I'm going to break my assembly everytime I make a mistake. Which is pretty common.
