Kent,

Something in it where it initiates the command upon loading it. I would prefer it to not initiate until you type MBR.
....
That "something in it" that initiates it is the last line in the file:
(C:MBR)
That runs it when you load it. I don't ever do that in my own routines, but a lot of people do, I guess on the assumption that if you load it you want to run it, but obviously not thinking of putting it in the Startup Suite. I was modifying someone else's routine there, and that part remained, but if you remove that line, it won't run it every time you start AutoCAD.

I've used this routine for a while and works wonderfully, but for some reason I've started having issues with it failing and giving a Unknown Command "NON". Any help is appreciated!
Could you be using it with "T" intersections? Without trying it out, it looks like the routine needs the thing you're Breaking to extend to both sides of the thing you're breaking it around, by at least as much as the half-gap size. If it doesn't, one of those break points will return nil, and if it's the first one, that is, there is no point on the object to be Broken that's past the intersection by that much, I assume that will "break" the Break command, and the "non" controlling for the second break point will then come at the Command prompt as though a new command, rather than being inside the Break command it's expected to be a part of.

Hi @Anonymous, I did not write this routine but similar to what Kent said if half the break distance you enter is greater than the length of the line on either side of the break point you will get this error. I have added an error function to it to restore the osnap settings if it is canceled after reading comments about the osnap settings changing.

A few comments....
That lists a localized variable that doesn't exist in the routine [PT2], and sets a variable that is never used [pr], and lists an argument in the *error* handler that is never referred to [msg]. Also, it doesn't let you know if there was a "real" error [not just a User cancellation], and regardless of whatever the error might be [even a User cancellation with ESCape before OSMODE has been changed], it reports that it restored the OSMODE value. The attached enhancement fixes all those things.
Also, if it encounters one of those no-such-point-on-the-object errors because an end is inside the gap-Break range, it won't Break it at all, whereas I would want it to Break it appropriately on the one side where it can. The attached does that -- if a nominal Break point would be before the start of the object, it uses the start point instead, and if it would be past the end, it uses the end point.
And it has some other features, such as that it won't accept zero or a negative number for the gap size, and on first use, it won't accept Enter but will insist on being given a value.

@Kent1Cooper, As I said I didn't write this, it is something given to me. When I use it, it works. I can't comment on how the it is written. If it doesn't work as it does for me then nobody needs to use it. I am sure something better is available somewhere.

[Get your auto-correcting program to accept "lisp" instead of correcting it to "slip."]
Are you talking about breaking Lines based only on their length, and with no consideration of any relationship to any intersecting object(s)? That's a very different operation, but certainly can be done.
And would "lines with 70 mm length" be only those of exactly that length, or did you mean "70 mm or less"? If so, is there some length below which it should switch to two sections with a gap, and some other length below which it should not be broken at all?

In an easy explanation It's about making a continuous line to dashed line with 2 mm gap space.
But the important part is I can't and i shouldn't use line type or custom line type.
Just break a lot of number of lines to 2,3,4 or even more segment base on their length.
There is no intersection object or any relationship just making 2mm gap on simple multiple lines based on their length.
In the picture attached, there is a red line for example that i want that to be broke with 2mm gap. in a full DWG there is 500 or even more of this line. i want a way to select all red lines and make them broken with that gap.
For your next question:
70 mm length is just an example if i want to be more precise i want lines with 5 -50 mm length broke to 2 piece with 2mm gap
Lines with 50 -100 mm length broke to 3 segment with 2mm gap
Lines with 100-150 mm length broke to 4 segment (2mm gap)
Lines with 150-200 broke to 5 segment (2mm gap)
Lines with 200-300 broke to 7 segment (2mm gap)
Lines with 300-400 broke to 8 segment (2mm gap)
And more lengthen lines broke to 9,10,11segments
It's unfortunate that your breakdown of lengths vs. number of segments is not a regular progression. Some are 50mm ranges, some 100mm, there's no length range to divide into 6 segments, etc.
Would it be acceptable [it would certainly be far easier to encode] to have it break all selected Lines [and even other things like Circles/Arcs/Polylines/Ellipses/Splines, if you like] into however many segments it takes so that there are 2mm gaps between them and each segment is no longer than 50mm? I have code that would provide a starting point for such a routine, in the DIV+ command in DivideMeasurePlus.lsp, >here<. It will place Points or Blocks or marker Lines at whatever quantity is needed so that the spacing doesn't exceed a specified maximum distance. It should be relatively easy to modify that to Break instead of drawing something.
