Creating a break block

[Anonymous]

I am interested in trying to insert a block and have it trim itself. I was messing around with the wipeout commnd to do this. But I think I will end up fighting the display order to much. I want to use this for my plumbing sysmbols as far as pipe down, pipe up, and valves. Wondering if anyone could shed some light on how to do this. If I am doing this with a lisp routine how does autocad know where to trim the line and what line to trim just from a block? Thanks in advance.

Scott,

This is how I'll go about it:
1)Block to include 1 attribute with
block insert point at center point.

2)The atttribute will be the first
entity in the block and will contain
the break dimension. Tne block attribute
will be invisible and constant.

3)The lisp routine will insert the block
block, retrieves the break dimension,
determines the break points on the
line (based on block insert point and
break dimension) and then breaks the
line.

Hope this helps.

At www.afralisp.com there is a tutorial and lisp code for doing just this.

I think you should address your post to the
original poster who's asking for help.

If you're replying to my post, thanks anyway,
but currently have no urgent need for it.

Cheers.
