Break a line at a point

[Masroor Javid]

How is it that when I click on the "Break at Point" icon, (in Dashboard) and then click on a line expecting to enter a particular point where the line will BREAK into two pieces thus creating two different lines having a common end-start point; the ACA then breaks the line and deletes one piece leaving only one line trimmed at the point given for "Break at Point" command?
Is this a wrong entry in the commands related to the specific icon or has this command changed and needs further input?

Hi Masroor Javiid,

I just checked "Break at Point" and it works for me. Make sure you are selecting "Break at Point" and not the "Break" command which will act in a fashion similar to what you are describing.

Hope this helps,

Here's a siple routine I wrote many moons ago called brat, a.k.a. BR@t.

This routine will break a line @ the intersection of another line by picking the line to break and the intersection to break it at.

This was a early predecessor to the break @ point command.

Maybe it'll help, maybe it won't..

(defun C:BRAT()
(setq user (getvar "OSMODE"))
(command "OSNAP" "int")
(command "BREAK" pause "F" pause "@")
(setvar "OSMODE" user)
)

Indeed when there are two intersecting lines, the “Break at Point” functions well. However if there is only one standing alone line and I try to break it at a point, one part of the line is deleted.
There are two questions:
1. Why the part is deleted?
2. Which part is deleted?
In any case thank you for your replies.

I have to agree with stelthorst on this. Make sure you are selecting the break at point command. It's the one that looks like a rectangle and on the top like, there's a small break on it. I just tried it on a line and it did exactly what it's supposed to do. I drew a line, clicked on break at point and selected the line, then I selected where I wanted the break to be. It looks like nothing happens but, when you click the line, you should see it as two separate lines.

Hope that helps.

Thank you for your reply.
Strangely enough I noticed that when I clear all Object Snap settings the Break at Point works correctly even on a stand-alone line (no intersections with other lines).
When I have Object Snaps set to “endpoint” then using the "Break at Point" will delete the segment of the line (stand alone line) from the nearest endpoint up to the selected for breaking point.
