Any time you see a member selection, you can either click the name or click on the "Select..." button to see the pop up member selector. The member selector will show a summary of critical checks for the given design so you can see at a glance what the most optimal section should be. The top filters allow you to filter down by category (eg. F17 timbers) as well as dimensions. RB1___ClearCalcs__1_.gif
