As you know the block determines what the hat can be. Any Engineer, Draftsman or Structural Detailer knows that if the angle is <90 degrees at the breakline then it will be off by several degrees of taper at the 6" crown height. If the angle is >90 degrees at the breakline it will be over by several degrees at crown height creating reverse taper. One shouldn't need a block number to determine if the crown will be straight or not.
Which is why I leave it to the Engineers, the Draftsmen, and Structural Detailers to figure out the math and science behind creating the blocks, and my job is figuring out which of those blocks works best for what I want to accomplish. For me, I've had good luck with the straight sided dome for the majority of my projects.As you know the block determines what the hat can be.
