Thank you for responding to my post.
  My apologies for the confusion.
  I understand about the pair of Cartesian coordinates indicating the cursor's position from the absolute and movable reference points.
  I am trying to resolve that when I move the cursor vertically on the drawing page the Y value as read in the relative (movable) zero part of the lower portion of the screen does not track with the scaled value that the drawing represents.  However, the drawing's real world values do track correctly when revealed with the Dimension Lines tool.  Specifically, when the cursor moves 160' which is but 6" on the drawing the movable relative Y value reads 568 units.  For all the available adjustments I've tried, that 568 number does not change.
  And, would you tell me what are those units?  In LibreDraw and Gimp, there are a set of edge rulers indicating the page size that is being drawn/imaged onto.  In Gimp, the program defaults to pixels but can be adjusted to metric, British and other measurement systems.  I have looked into the LCAD documentation but have not found or might have scanned past that detail.
  I've done some more research through the forum using  "X-Y coordinate" as a visual search tag and eventually found a semi-related post that suggests drawing in full scale and then using the print scale function in the print preview window to bring the drawing to the intended paper size.  Because of my Gimp and LDraw bias, I had not considered this approach.  It seems to add perspective on the topic and also to the potential flaw of trying to draw within the finished paper size.  
  Does this explain the issue in a better way?
  So, have I failed to properly adjust a setting or is LibreCAD not designed to work the way I am trying to use it?
  Please advise.
