I don't have as much of a problem with the way the part's X axis is pointing. It all depends on which axis you feel is important or not. In this case, someone decided that it's more important for the Z axis to point up than it is for the X axis to point right. Makes sense to some people, not to others. (It happens to bother me, but I realize that it's arbitrary so I can get over it, if I have to, I guess...)
I think the real problem is that we have two independent coordinate systems in a part--the PART coordinate system based on the origin features, and the SKETCH coordinate system based on ???
Why not just use the part coordinate system? No need to ADD confusion!
I'm not sure why I'm the only one who's furious that they're paying this much money to watch massive bugs like this go unfixed for ELEVEN YEARS, but I'm going to keep bumping this thread even if I'm the only one doing it.
Not sure what all of the fuss is about. The very first answer in this thread, way back in 2003, is correct; if you select the plane in the model history tree on the left, and right click on it, there is an option to "flip normal". This changes the default side of the plane that the sketch is on.
The fuss is about the origin planes (specifically the XZ plane), which cannot be flipped-- see the fourth post in the thread.
But I have never, in thirteen years of using Inventor, experienced this issue, so I'm also uncertain what conditions cause the problem. If I create a block starting from the XY plane, then start a new sketch on the XZ plane, it's on the +Y side. Look At the new sketch gives me a Top view, not a Bottom view (this is using default Inch template with up = Y-axis).
