Naviate's Rebar Color is a great ideea. But I would love to have a Rebar Color drop-down button directly in Revit. This drop-down should have multiple choices: Color Rebars by Partition, Color Rebars by diameter, Color Rebars by Phase, Color Rebars by owner / Workset.
Currently I am using Diroots One Filter to achieve such colorizations, but it takes time and multiple clicks to select, filter and apply individual colors to each type. Less than ideal.
