I have created an rfe - no. 1343044 - and attached a drawing to the rfe illustrating this feature. Emil, please review the rfe to confirm this is what is wanted: http://sourceforge.net/tracker/?func=add&group_id=93438&atid=604309
Hello,
Great you made the RFE Adam! It looks right to me. But in your example image the repaint starts in one node point and ends in another node point, and it should not work like that but as you say in the text; start and end can be at any point of the line. But maybe that is clear without changing the example image?
I don't know if we need to clearify how the pencil should behave when the start point is on the line but the end point ain't. In illustrator all parts of the line after the start point is removed and replaced by the new line you just drew. Do you follow what I mean?
Regards Emil
