My example is a time compressed scenario so yes, these are representing view selections from the menu options. Each letter would be a separate object. The sum of all of them being after some time of working with the document.
What I'm trying to convey is that in the first 6 view examples, what I see is correct, to be expected.
Where you say "after making the height changes" is the problem. I expect them to be all the same height when looking at any view where the Z axis is visible. As in the top and bottom views will appear "flat" but any side views will appear with the objects at random heights.
The X and Y positions are where I expect them, but the Z position varies for each one when you would expect that it shouldn't. As in, you had to make the height changes where as the opposite is my experience. I've got to move it all back to the same plane. As in put them all back with a Z value of 0.
How to say it.. Disregarding any orthographic views, concentrating on only the cardinal selections from the menu, where X and Y are visible and Z would only be visible in the two dimensional sense that if I had multiple objects at the same X,Y one of them would be above or below the other and that would be visible when the Z axis is visible, (any side view selected), otherwise one is obscured by the other when viewed from either the top or bottom.
In that scenario, you've been working on said drawing for "a while" and when you go to start working with it where you're going to start making solids, extruding faces on those 2D shapes and that first time you switch to any of the sideways views, you're expecting all of the objects on the same level and they are -NOT- .. How did they get "all over the place", when they shouldn't be?
