ssget Again!. this time lines a bit more complicated ..maybe?

[scubastu]

This lisp takes each line and draws a new line calculating by bowditch (or compass rule) to make the end coordinate the same as the beginning. It finds any block at the end of the line and shifts it to its new corrected position. I've attached an dwg with an crude example of traverse. Obviously the traverse to be adjusted are the lines in the loop or circuit and you need to select these from start to finish in order.

Now the problem.. I want to shift any lines that radiate from pnt 2 and that are not in the adjusted circuit to the same new position. <-- ok done this but a little messy.

How can I assess anymore continuing lines and blocks starting from the ends of these radiations and shift them with the radiation? Possible?

maybe something like..if radiation exist get, assoc 11, and if block or radiation exist at endpoint include in radiation set loop until nothing then continue with rest of program.??!!
