I wondered if adding extend statements in-line with data would offer a solution, or at least some insight.
If so I have not found it yet. Interested to see if anyone else can: 1. Make the loop generate anticlockwise and produce a gap at station 2, with the second instance of 2 on the right of the first instance. 2. Produce a gap at station 7. Here is my first attempt. extend start extend right 1 2 1 0 -10 2 3 1 0 -10 3 4 1 45 -10 4 5 1 45 -10 5 6 1 45 -10 6 7 1 90 -10 extend left 7 8 1.71 225 60 8 9 1 225 10 9 10 1 225 10 # extend ignore 10 2 1.8 225 -32.2 extend right 7 11 1 90 -10 ie this traverses 1 2 10 9 8 7 then backwards through 6 5 4 3 2, then 7 to 11 Not at all the sequence the data is presented in the data table above The ignore statement before leg 2 10 is ‘ignored’ if it is uncommented. START 1@extendedloop RIGHT 2@extendedloop RIGHT 10@extendedloop RIGHT 9@extendedloop RIGHT 8@extendedloop RIGHT 7@extendedloop LEFT 6@extendedloop LEFT 5@extendedloop LEFT 4@extendedloop LEFT 3@extendedloop LEFT 2@extendedloop #now back to 7 BACK 4@extendedloop BACK 5@extendedloop BACK 6@extendedloop BACK 7@extendedloop RIGHT 11@extendedloop # and 7 to 11 Done Bruce
