With the R2 version of 2016 Revit we were introduced to Global Parameters.  As Dezi and myself have been looking into how to utilize them she noticed a nice quirk related to them.  Previously I have posted about beams and associating them to columns and then clarified that post with a follow up.  When entering a value for the attachment distance Revit will only allow this to be a positive value, which will move the beam towards the center of the column.  Dezi had noticed that if a global parameter is associated you can enter a negative value

Now I want users to try and use Global Parameters and see if they can use them were we can’t have a negative value.  If you find them please comment to this blog.
