Since 2015 Revit has provided the Rebar Number which automatically assigns bar marks to all reinforcing within the project making use of the partitions to generate a suitable bar mark.
This is of course a very useful feature and does provide an efficient method of bar marking. However, if you have then issued the model and need to make further changes to the model then you probably do not want the Rebar Numbers (Bar Marks) to change and of course, being automated this can happen.
A safe way of working is to use Dynamo to automatically synchronise the Rebar Number to the Schedule Mark (this was the method of bar marking prior to Revit 2015). This will obviously only be run prior to the issue of the drawings/model to keep a record of the bar marks.
If the Rebar Number does not equal the Schedule mark then we can take ‘manual’ control to rectify the problems.
Here is my Dynamo Script below.
It is a very simple routine that selects all the Structural Rebar in the project, gets…
