What is Absolute coordinate?

Please see this website

Absolute coordinates refers to a Cartesian System that uses X, Y, and sometimes a Z-axis to establish a point some distance from a common origin. For example, the picture shows an origin point of '0,0' and the absolute coordinate from that point is '8,7' making it8 along the X-axis and7 along the Y-axis.

As an example, in a CAD program you could draw a line using absolute coordinates. To do this start by entering the X,Y value of your origin point. To start a line at one to the right, and four up, as shown in the picture, type1,4. The line could then be drawn four to the right by using the absolute coordinate of5,4.

Absolute Coordinates uses the Cartesian System to specify a position in the X, Y, and (if needed) Z axes to locate a point from the0-X,0-Y, and0-Z (0,0,0) point.

thanks.

in simple language absolute coordinates are the coordinates in which the whole dimension is calculated from the starting point.

A way of inputting points based on AutoCAD's origin.

Absolute coordinate refers to a Cartesian system that uses x,y,z axis to establish a point some distance from a common origin.

specify a point by entering its X and Y values in the format X,Y or  X,Y,Z for3d point) use absolute x,y coordinates when you know the precise X & Y  values of the location of the point
