There is no problem in drawing that type of break it just involves a custom lisp to break the lines and draw wiggly lines, the amount of wiggle may have a couple of FUZZY values or scale factors. even a block just scaled to fit. 

 

To write your own lisp and its a good task to start learning, Draw a line say 1 unit long vertically one end at 0,0, the turn off snap and draw a wiggly Pline. Use list select pline and copy out the co-ords, to notepad You have 1/2 your code now, just make the points, use a scale factor on the Y value to adjust the points for the 2-3/8 then can draw the pline at correct position.

 

Ok now the easy answer make a block and again draw a line, do the pline, erase the dummy line, save block. you can insert the block and scale it to suit the length required. insert block twice, after breaking line. I would turn second insert upside down so looks a bit more random. 

 

Ok I have avoided line work on any other angle than horizontal, on purpose, you can pick a point on 1st line break it, then perp to other line and auto break it also. This involves getting linework details like angle of lines. The actual pline could have randomness added to it so no 2 plines are quite the same by in example vertical, adjusting the x value within a range so 2 breaks don't touch. 

 

So have a go make a block and your homework is in lisp,

Getpoint pt1,

Polar for 2nd point, based on horizontal line,

then Break using 2 points,

getpoint again Pt2 using perp ,

break other side.

 

Simple block answer.
