When using the right click command on an element to select All In Project on a particular fabrication item such as a 450 wide * 125 tall * 450 radius 90 degree Legrand ladder bend, instead of selecting all of that item type in the project it selects all bends regardless of the bend radius, size or type. This is not the way Revit usually works.
When assigning custom parameters the schedules don't work like Family Type schedules should and when resizing or replacing elements automatically using the various tools a straight length will retain custom parameter values whereas a fitting will delete the values when it shouldn't.
I'd like Fabrication content to obey the Family/Type relationship in the same way that everything else in revit does.
