Artur,
I changed the meshing to 1m element size and the type 3 error went away when I ran the model again. I had the bottom 3 levels working fine and then when I copied up the repetitive storeys it seems to have sent things worst as I have now got incoherent mesh error in the model which I have tired everything to sort out but cant seem too, slowly losing the will to live with Robot, LOL, I have a attached the model in the transfer link below, is there an easy way of getting this incoherent mesh warning sorted? I have looked through some of the previous posts on incoherent mesh and tried a few solutions but none have worked. could somebody help me please if possible. I would thought I have some inaccuracies in the model however I have tried aligning it as best I could.
Simon.
