I ran into this post at What Revit Wants http://whatrevitwants.blogspot.com/2015/02/automatically-renumber-mark-parameter.html?utm_source=feedburner&utm_medium=twitter&utm_campaign=Feed%3A+WhatRevitWants+%28What+Revit+Wants%29 and was having some issues. Not all of the elements change their IDs in the manner I was hoping. This is the project - so I need to change all of the element IDs of the strutural framing to be in increasing numerical order. After the forth beam, the element IDs no longer go in increasing order. I need them to be in increasing order so when we bring this into RISA the nodes will be in the correct order.
