Les coudes que tu essaies de placer on l’air d’être trop grand entre 2 des chemins de câbles ce qui fait que 2 coudes viennent se toucher. The elbows you are trying to place seem to be too big between 2 of the cable trays which makes 2 elbows touch each other ---

Thanks for your reply 😃 The problem is about margins on node elbow fitting if i change the margins it will pass but if i choose a complicated trajectory it doesnt works … ![margins](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/1/4/14bedbde98b1d6034c5437a23ef22391dd833c80.png) ---
