Hi Maxim, thanks so much!  I tried to write you back yesterday but had lost use of my mouse (just got it back).  I downloaded and opening the file that you flattened and it did seem to solve the problem of the axis being skewed.  is there anything I need to do to keep future elevations from needing to be "flattened"?  I have never had to flatten drawings repeatedly before and am wondering what is different about this one.  When you looked at the drawing from the front--it was obvious that some setting had been "off" in order for that to occur.  Is there anything I need to do to the file further to make sure it all remains flat?  Thanks again!
