What's actually happening is a part (a spacer) is being created on a pole. When I told the program to begin the sketch on one side of a washer, it went into the sketch mode. Now because the part being created is in a sub assembly that's in an even bigger assembly, it has to take into account all of the other planes from every single other sketch on every plane.
Often people tell me that Inventor is the greatest system, others say it's impossible to learn. It's just ironic that I got this (by chance, I didn't plan this), which to me represents insanity.
HAVE FUN WITH INVENTOR
