Does it have to be a lisp routine?  Could it be done using a script?

What would be the source for the data to draw the polylines?  Would it be a .csv file?

Update what parameters?

Can you provide a sample drawing?

First of all, thanks very much.

1、the lisp source file and the odcl file are in the attachment.

2、I want the program can do this
     â‘  when i click the Draw button,  i can choose one point in the drawing area as the circle center and the text in the textbox as the radius, and the circle appears.
     â‘ˇwhen i drag the slidebar, the circle radius can be changed and it can be shown in the area at the same time.

Thank you very much.
