How is the origin in a 2d sketch determined?

[donovandigital]

It seems no matter how much I futz around with planes, axes, and work points, ssoner or later I will make a 2d drawing and find that the origin (which is what I am assuming the intersection of the gray lines are) is not where I need it to be. How does Inventor decide where to put it? Can I change it manually from within the sketch somehow? I realize I can move the UCS but of course that will affect everything else, right?

Many thanks in advance

It would help if Inventor did not change the axis between sketches within the same part.  I put down a circle and an intersecting rectangle.  When I change the size of the circle the rectangle rotated the axis.  Now I can't align the part to the view, its no longer in my XYZ frame of "mind".  Plus the additional sketches that I want to do are all rotated from the original.  What a pain.  In the you know what.  Also a big waste of my time.  I must be using the wrong tools.

Or I don't know what I've done wrong.

Hi! I think the behaviors have been captured in the discussion here. I don't need to reiterate. We are aware of the behavior and negative feedback. We are investigating how to improve it. In the meantime, you can right-click on the sketch -> Edit Sketch Coordinate and realign the X and Y direction.

Many thanks!
