Standards for stud groups

[Travis Cobbs]

The proposal we agreed on allowed for all different stud types (hence the N in the filename template). So, while there aren't any stud groups for tubes at the moment, what we voted on allows for them. An option to allowing Y-axis scaling of stud groups is to update the text to only allow for topside stud groups, but I don't think we should do this. There aren't any tube stud groups yet, and there may never be, but I don't think they're something that should be forbidden.
