Topic: I need a lisp to draw a line and break object it touch in one step

[meja]

I want to draw a line（or arc pline etc）and break any object it touch in one step。EVen I think use CAB's Breakall Function，But I fail。 So who can help me，give a code to do it！

You may have issues with the first option.
From memory, an arc can't enclose 360 deg in Autocad

I'm surprised Alan's code fails in any other situation.

you misunderstand me，CAB code is perfect，just I cant mod it for my use
ps CIRCLE can be break（360 degree） with line if use breakall lisp，but it error with arc

I've mod. CAB's Break Objects routine to suit my needs... Perhaps it'll work with your examples... Test it if you have a time...

You should use : (c:BreakAll-nogap)

many thanks
my idea is while I am drawing a line，it breaks any objects it crossed。Not to select line I have drawed and other objrcts。

While you draw, CAD is in dynamic mode and it can't predict where your command is going to end - cmdactive sysvar, therefore you can't break object in desired location; only when command is finished CAD knows position of entities and can do break if that's intention... But CAB did his routine to work with gaps, so you'll have to modify my version to be without gaps - pull info from (c:BreakAll-nogap) and add it to Break this with other object for single entity breaking... But for me this is what I was needing - BreakAll... If you need something more sophisticated you'll have to code for it and not wait on the plate for every single request...

ok, good to know.
