Absolute coordinates (the origin lays on the coordinates 0,0) 2. In LibreCad Cartesian coordinates can be inserted considering two cases, that may give the same result: 1. The coordinates can also be defined as the positions of the perpendicular projections of the point onto the two axes, expressed as signed distances from the origin, the picture explains those concepts.
Each reference line is called a coordinate axis or just axis of the system, and the point where they meet is its origin, usually at ordered pair (0,0). A Cartesian coordinate system it is a system that specifies each point uniquely in a plane by a pair of numerical coordinates (1), which are the signed distances from the point to two fixed orthogonal directed lines, measured in the same unit of length. If you are already into others cad system probably this little chapter is not necessary to be read.

This bar is a bit more specific it allows to: This is another common bar that many other programs have, there is nothing specific considering the “cad side”, the icons' function are in order: (*) (Please notice that LibreCad operates with.
This bar is the basic bar that you may find in any other applications, is quite standard, looking at the picture under the title there are in order :
