I need to 'break' multiple lines between 2 points, but retain the 'broken' part

[VisionSurvey]

Hi all,

 

Not sure this is the best time to post, with this attack going on, but I figured out that IE still lets me onto the forums and I don't want to give in to the attack. So here goes:

 

As part of my job I regularly need to remove a section of a line (very often multiple lines close together), but I need to retain the section I 'break'.

 

The break between 2 points tool deletes this area, I need to move it on to another drawing.

 

Currently I draw a box covering either end of the section(s) I want, single break on the intersection points (twice per line) and then move the section I want to retain out of the way - up 10,000, which I will later move to a new drawing and move back down 10,000.

 

I was hoping one of you more knowledgeable folk know of a better way of achieving this since it's arduous to say the least!

 

Also a bit more of a long shot: I need to do this tasks across 14 drawings - removing anything within the areas. I do this by drawing the areas I want removed on a drawing with all models bound, then paste these areas (square polylines) into each individual drawing and complete the above breaking.

I doubt there is an easier way to complete that, but I thought I may as well ask.

 

Please let me know if I've not explained well enough.

 

Thanks for any input.

Have you tried the break at point?

If I'm reading this right, you want to break a whole bunch of objects all at the same time, then be able to lift the area between the breaks out, right?

Wouldn't it be easier to copy the area of interest, trim the outer parts you don't want, then come back and trim the inner parts you don't want?

Come to think of it, I would probably make a copy of the drawing and trim inside the box in one copy and trim outside the box in the other. If it is something visual only, I would use wipeouts.

go over to theswamp.org, registration is required I believe, but then go to

http://www.theswamp.org/index.php?topic=10370.0

and download breakobjects21.lsp

 

It does lots of different types of breaks for you, creates a dcl file automatically. Make sure the folder you place it in is on the search path as the DCL file needs to be found when running the lisp file.

If the OP had answered "yes" to my question, that's exactly what I was going to suggest!

I think this was covered once before is it "extrim" ask for inside or outside trim of a polyline line etc its a Autocad command.

 

Like above do twice in & out

 

Check yeah its "extrim" does what you want copy the trim line to the clipboard so can use in two drawings

Thanks all, trimming inside & outside in different drawings would work, a pain with 14 separate drawings (i do this a few times a week) - but still faster than the 'break at point' method I'm using now.

I'll check out theswamp.org and see what that lisp routine does.

 

Edit: rkent - that lisp routine is excellent, thanks for the link.

And thanks to CAB for being so generous with his awesome routine.
