Hi!

I would like to achieve a trim/extent feature like in many CAD-like
application can be found.

Here is a little screenshot what I trying to do:
http://khiraly.googlepages.com/trim_extend.png

Here are the steps what I did:
There are two lines and a circle, so
1. I converted the circle to path
2. I opened up the circle
3. I duplicated the line, and go to the Path->Cut Path menuitem
4. I repeated the above step to the other line

Sadly this precedure involves some imprecisement, I zoomed into, and
created this screenshot:

Can somebody propose a precodure where the result is mathematically
correct, and does not
have imprecisement?
Needless to say, that I cant union the three paths together...

Or should I wait until a trim/extend tool arrives? (I use rev 20844, from today)

Any ideas?

Best regards,
 Khiraly
