Hi Antonius, thank you for your time.
I don't understand how you got that "d7". In the file d7 is d1, which is correct.
I am still struggling but I did more tests :
- If I import the chain_01.asm in an other assembly without flexibility, it regenerates correctly
- If I add flexibility on chain_01.asm on the required parameters without changing values, it regenerates correctly
- If I modify any of the three values for the end links, regeneration fails for "link_start.prt" which keeps the original values ; link_end.prt regenerates correctly with the updated values.
It must be an obvious mistake but I still can't find it !
