I opened a part today and noticed that it had collapsed into itself.
This should be a rectangle 85x15.75:
On closer inspection it appears that the vertical lines somehow became zero length lines. Why does this happen?
Edit: I should mention that I was able to repair the skecth by making the 85" dimension driven, then dragging the line over...
I was able to repair the sketch by deleting the Vertical constraint (and then putting it back in again).
Very interesting.
But this brings up a question - why are you not using centerpoint rectangles?
And for many years I have recommended against horizontal and vertical midpoint constraints to constrain rectangles.

I assume you mean "...why are you not using centerpoint rectangles?"
I originally drew this part before the feature was integrated into Inventor. If I was to draw it today, I would.

Is this why?

No, my reason was un-predictable results with sketch fillets or chamfers http://home.pct.edu/~jmather/AU2006/MA13-3%20Mather.pdf , but now you have given me an example of another reason.
Back then centerpoint rectangle tool didn't even exist.
