The spacer plates in the Splice Joint needs work. Right now there are no options other than whether you want one or not.
I would like to see the ability for it to round off to the nearest 1/16" or a setting set somewhere in the program similarly to the round off of stiffeners. Right now it will even use 256ths and no shop around here wants to see that. They want even 16ths. I have to erase the joint box and manually change the thickness to make this happen.
Also, it would be nice to be able to set an offset horizontally or specify the edge distance on the vertical sides. These plates should be symmetrical for ease of fabrication and especially installation and not stick out past the splice plate. If the edge distance of the splice plate and beam end are not the same this does not happen. Ex: 1 1/2" edge distance for the splice plate and 1 3/4" to the end of the beam. I use a 3" wide spacer, so again I have to erase the joint box and move the plate over 1/4".
