i solved it, for anyone interested you gotta subdivide it in areas, but each one's side, must have the same lenght than the adjacent area, since you have 4 lonely pillars there, you need 13 areas there
You mean you have to think about how to lay out your model!?!?!? The Horror!! SAP is pretty user friendly on how it allows sub-meshing, but you have to give it a fighting chance, it isn't a plug-n-play modelling software.
I am not sure your model will work real well. In the lower right picture you have a ton os joints barely offset. Those shells are not going to work very well that way.
