hi
i am looking for some large calculation stuff.
lisp To read area of selected polyline, triangles ,rectangle, circle and other shapes with details of calculation.
lisp will give Area of an entity with single command. which will give detailed table of calculation for all the selected shape , But how does it calculate the area e.g. (base and height of the triangle and using ½ * base * height formula.) lisp gives each shape a unique number by selecting order , then marks the length of each side of the triangle on the drawing with the area displayed at the centre of the shape Then it prompts the user to specify a location for placing the area of each shape.
something like below
any help thanks in advance
