Hi

I am modelling toriconical bottom with large end 1900mm id and small end 0 with a drain nozzle of 50nb at the bottom.With this input ,half apex angle is calculated as 70 degrees and when i am attaching nozzle it is being shown as invalid cone geometry.Plese tell me whether ASME Sec VIII Div II allows to use a cone with half apex angle greater than 60 degrees and if it is not allowed, tell me how to model it.
