Andrew,
Good idea - Thanks
I made the jump from 11.5.1 to 2013. I have been idle with mechanical design layout for several years. So some of this could be my learning curve. I really like this product. Have used several other packages and wish I knew more.
Bolts are found in Tool Sets: Detailing, Fasteners, Bolts - Nuts - Washers...
I have tried but could have missed the place where thread length is controlled. I have gone over the items available at least twice. To the best of my knowledge this was not available even in 11.5.1
