Practical Use of Dynamo BIM - Updating Title Blocks

In this article I want to describe a very practical use of Dynamo BIM.

We often have a situation where we need to update titleblocks. It can be very time consuming to have somebody sit and update the Revision and Issue Status on a 100 drawing sheets. But it has to be done.

With 5 nodes in Dynamo we can make these changes in seconds. Here is our scenario. We have 100 drawing sheets in our Revit model. The issue status is currently Tender.

We need to change this to Construction on all 100 drawings. If it takes about 1 minute to change this manually on each drawing thats 100 minutes. We also run the risk of the modeller getting bored and going for a cup of coffee or mis-spelling on some of the sheets.
This is where Dynamo Bim is our best friend. I can write the program and have the whole job done in under 3 minutes. How mush time and money does that save.

all we have to do is place the nodes shown in the image below into your Dynamo BIM workspace.

Categories: This nodetells Revit to get the Sheet Category

All Elements of Category: This node selects all the sheets in the model.

These nodes are then wired together

Element.SetParameterByName: This  node is wired to the All Elements of Catagory node. It allows us tos pecifiy a parameter, in this case the parameter to change is Issue Status. 

Run the above code. All 100 drawing sheets are changed.

Dynamo BIM can be used for all those time consuming laborious tasks that we don’t like doing. Especially when the pressure is on and we have to get drawings issued.

Where can you learn more. Come along to one of our 1 day Dynamo BIM workshops.
These workshops are held regularly throughout Ireland,UK and ocassionally in the UAE. If you wish to find out more information, please feel free to contact us at info@siscin.ie

If you would like us to run a workshop in your area please contact us and we can organise a workshop.

  1. Hi Dan,

    This is really useful. Having a few offices at our company we run the office address as a generic annotation parameter, selected through a drop down menu. Any suggestions how to set this through Dynamo?

  2. Hi Lee,

    Thank you for your comment. You can set this parameter the same way as above. In the string node just put in the name of the required parameter. Ensure that the text in the string is exactly the same as the parameter.

  3. Thanks for the quick response. I've attempted to do that, as I assumed that would work. Doesn't appear to work. My address is a nested generic annotation which runs off a text file to find the latest office address.

  4. You could try reading the information directly in from the external file

  5. Why not an shared parameter on project information with status info?

  6. This looks very useful! I am just beginning to look at Dynamo... Are these saved within Revit and can be used again?

  7. These are saved as a file with an extewnsion of dyn. They can be used as often as needed

  8. I've been using this methodology for a while. Though, don't need Dynamo. What we could use Dynamo for is to apply the status to drawings of a particular revision date ? The system I have now works great and is quick though you have to grab all the sheets you want to apply the status to. Dynamo could pick out those sheets for me ?

  9. It definitley could. dynamo can add to your current work flow
