Working with Lines &amp; Line Styles Properties: Lines  Edges and Endings   Type of Line and Line Width   Start Arrow &amp; End Arrow   Basepoint We've left this setting for last since it's a bit tricky. For any sort of line or figure, the initial settings in the X,Y,Z tab of Properties show the X-Pos and Y-Pos of the basepoint, which at first is the upper left corner of the frame or bounding box. In the case of a straight line, X-Pos and Y-Pos refer to the initial point from which the line was drawn. The other spinboxes in X,Y,Z show Width and Height of the bounding box - except for a straight line, which is defined by Width (i.e., length) only, plus the direction (Rotation) of the line, and its thickness. This condition is true for the Line tab Basepoint setting of Left Point. If you change the Basepoint to End Points, the X,Y,Z tab now shows spinboxes for X1, Y1, and X2, Y2. For a straight line, this means that X1 and Y1 refer to the starting point of the line, i.e., where the beginning of the line was when it was drawn. X2 and Y2 refer to the coordinates of the other end of the line. The example below is for a straight line - where you can see that X-Pos = X1, and Y-Pos = Y1. For anything more complex than a straight line, the values refer to the bounding box, in which case X1 and Y1 refer to the basepoint as set in the X,Y,Z tab, and the X2 and Y2 values refer to the width and height of the bounding box, and therefore will always be positive numbers.
