Actually I need help with creating a LISP where can get the point to draw the circle on each tip by offset tip line by certain distance. Please kindly refer to the attached file. As u can see in the first picture, all the lines are in the same layer. But what I want are all lines which highlighted in blue because I want to draw circle on each tip and numbering them clockwise or counterclockwise (as u can see in the picture). Do you have any idea to automate draw the circle on each tip clockwise or counterclockwise by prompt the user to enter the offset distance and circle diameter? The attachment file is just a description to my need, it's not a real drawing. The main propose is the last picture. Any help or other idea would be appreciated. Thank you.
