Side Rail Anti-sag

[julian]

Hi, I am trying to install side Rail Anti-sag onto my model which I have previously done hundreds of times before, however I have a section of my model that comes up with the following message " Beams have bad position" and won't install the Anti-sag. Never had it before and I can't find anything else wrong in the model. Any Ideas!!

Hi,

Set your Units to maximum precision (8DP) and then check the rails / purlins are coplanar and parallel. even a minute error will stop the joint working.

Hi Aleck,  thanks for that I discovered the columns were 100th/mm off plane not sure how but its now sorted.

Cheers
