It would be great if you can pick a specific depth when using the auto size feature in the Floor Joists Module when using I-Joists.
Many times you can only use a specific depth and it doesn't matter what series of I-joists work.
This is a good idea I can see where you are coming from. Instead of having the grades of joists available you would have the size of the joists listed. Then Auto-Size would go through all the grades using only that specific size for each grade and return your results.
This is actually a pretty big request because it's a fundamental change in the way that the Auto-Size works. It is grade then size based. I have forwarded this on to engineering though to see what they think and we will see if we can get this in to StruCalc 10.0.
