The name of the function includes a special prefix 'c:', which causes AutoCAD to recognize the function as a regular command. The user, upon typing 'pointlabel' at the AutoCAD command line, would be prompted to pick a point, either by typing the X and Y coordinates, or clicking a location in the drawing.

Hi, If the coordinates of three points a , b , c are initially known, and if try to draw an imaginary line between points a and b , how can find out if point c lies on the line? Z-coordinate of all points will always be the equal. Go to Solution.
