It is the relative zero point. If you want to know how to use it try the following: Adjust your view so the absolute zero point (the large red cross) is in the middle of your screen. Scroll your mouse wheel until you can see at least 3 big squares of grid in every direction. Now move your mouse pointer to the Drawing Toolbar and select to draw a Line using 2 points. Turn on grid snapping (click on the snapping box with dots in it), it should now have a dark background. Your mouse pointer becomes a cross-hair, indicating you are in drawing mode. Click on the absolute zero large red cross and move your mouse a little but do not click again yet. You will notice as you move your mouse around that the small red cross in a circle (the relative zero) now is exactly at the true absolute zero, and the line you have begun to draw extends back to these two (coincident) zero points. Press the escape key to stop drawing and move your mouse away again without clicking. Now look in the bottom left hand corner of the screen and you see four pairs of numbers. Ignore the bottom two pairs and look at the top two as you move your mouse around without clicking. Hold your mouse still and observe that the two pairs of numbers are the same except that the right hand pair has an @ symbol before it. The numbers tell you where your mouse pointer is in relation to the zero points. The left pair is the position of the mouse pointer from the absolute zero and the right from the relative zero. Next select 2 point line drawing again and click on the absolute zero but don't move the mouse. The numbers show 0.00, 0.00 indicating the line you will draw starts at absolute zero. Now move the mouse vertically two large squares click on that point but again keep the mouse still after clicking. Now the numbers show 0, 200 (or some other multiple of 2 units), indicating you have moved only vertically, and the relative zero point has moved to the point you clicked.. Move your mouse pointer two large squares horizontally to the right then hold the mouse still and look again at the numbers. The left hand pair of numbers shows something like 200, 200 (or again a multiple of 2 units). This shows that you have gone the same distance away from the absolute zero point in both vertical and horizontal directions. The right pair of numbers shows 200,0 (or equivalent) showing you have moved that many units only in the horizontal direction from the relative (or if you prefer "temporary") zero point. Click again and hold the mouse steady, the relative zero jumps to where you clicked but the numbers don't change. Now begin to move the mouse down two large squares . Immediately the first number in the right hand pair becomes 0 while the second number shows a negative figure (say -200) because it not only shows moving vertically but indicates which direction. Hover the mouse over the point 2 large squares down and look again at the left hand pair of numbers it will show 200, 0 because that point is 2 large squares away from the absolute zero point horizontally but has returned to the horizontal axis and therefore the second number in that left hand pair is 0. Again click on that point so that the relative zero jumps to it. Move the mouse pointer to the absolute zero point but don't click. Now the left hand pair of numbers is 0,0 and the right hand pair is -200,0 showing that the mouse has moved in the horizontal but in a negative direction. Now click on that absolute zero point and move your mouse a little away and back again, both pairs of numbers will show 0,0. Finally move the mouse away a bit further and press the Escape key. Your mouse pointer becomes a normal arrow indicating you have left drawing mode and you have drawn a square. Now it is important to grasp that the co-ordinate system numbers (the pairs in the bottom left hand corner) show the POSITION OF THE MOUSE POINTER, and have nothing to do with the lines you may have drawn. Select two points line as your drawing tool with grid snap still turned on,, Without clicking, point to the corners of the square and observe the pairs of numbers. Now, starting at absolute zero draw a second square over the top of the first but pause before and after clicking in each corner to observe how the coordinate numbers change. Play around with this concept using straight lines at first to understand it. You will continue to understand it when you start drawing curves as well. If you find the relative zero a little off-putting just remember that if it seems to obscure the intersection of two lines then clicking on the relative zero is probably clicking on that intersection. Finally, if you need to draw without the relative zero following you around, move the relative zero point to the absolute zero as you did at the very beginning of this exercise then in the snaps toolbar click on the lock relative zero (like the grid snapping it will have a darker background when the lock is active). You will have to do this each time you open a drawing.

Well done. I have been using LibreCAD for several years and I learned a few new tricks from this video. Looking forward to the next. Thank you.
Thanks RonS.
These tutorials are a huge help for a beginner.
just done this first one it was such a great help, can't wait for more
thanks , enjoyed it and learn'd a lot thru this tutorial , look out to see more
Very useful video and your teaching is clear. Thank you.
Thanks Ronny.very nice work.
Подскажите как можно создать кривую линию из точек на заданном расстоянии между точками?
thanks you verry much
how do i create the grid status again? i am in US
Snap on grid left bottom

I dont recomend in manjaro it desapers off screen no error no nothin i use qcad it didnt crush and it seems a litle more intuitive.
