Draw circle and numbering them clockwise/counterclockwise

[noadea]

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.

Let me know if you have problems

There are limitations for this routine make sure the U shaped lines are joined polylines.

Thanks for your code.
After I run your code, the result shows the circle at each end point of U shape (bubbleit[1].dwg).
Please refer to the attached file (circre1.doc), I want the circle be drawn at each tip of U shape (figure 5) by certain distance from end of tip (figure 3).

Just by tweeking that routine you can make it do what you want.

The process is identical, it is just a matter of changing the points using trig.

Why don't you play with it a little, and if you can't do it then let me know and I will change it.

Thank you fixo...
I just try your code to my other drawing but it can't work properly.
It only can work on the drawing that I've attached before.
How if my drawing is like this attached file below? (please refer to ex1.dwg)
Thanks for advance.

You may be able to use this routine.
Select the center, Select the the lines to have the bubbles added to.
Select the first end.
Then CW or CCW & the bubbles are added to the outside points & the lines trimmed.

You will need to adjust the text height & Bubble size.

CAB, I want it be like in the attached file below. The circle on each tip by any offset distance from end of tip.
