Hope this will be helpful to you...

I think you misunderstand the problem.
For instance, I can draw a parallelogram freehand, but then cannot get a parallelogram shape to exactly match it because of the problem I describe.
When I "elongate" UP a parallelogram shape (made with an OG parallelogram shape) that has exactly horizontal top and bottom lines, I need the two diagonal lines, on left and right, to
lengthen; and I need the WIDE angles (on the inside of the shape) at the inside top left and inside bottom right
to remain the same angle of degree.
It doesn't matter to me if the top line moves to the left or right. I don't care. Right now the program ensures that the line you're dragging
doesn't drift laterally, at the expense of changing the degree of its vertices. I need the opposite: the angles to stay the same, and I don't care if the line drifts left or right.
I need ALL the angles on the inside of the parallelogram shape to remain at exactly the same degree as I either widen the shape or change its height. I don't care about lateral drift of the top or bottom lines (the nondiagonal sides of the shape).
Does anyone understand this? Please, I have already spent 34 hours trying to figure it out. If the program won't do it, fine; just someone please tell me that. But I know that often in OG holding down some combination of the Shift, Control, Alt, and Command keys before clicking the mouse (or trackpad) and then dragging an object's handle will change the behavior of the program.
If I'm not making sense, I will post screenshots with arrows and labels indicating everything.
