Change Duplicate Marks automatically

DUPLICATE MARKS!

Have you ever been working with other people on the same Revit model, and you realized that there are a lot of Element’s duplicate marks? We’ve develop a custom node in Dynamo that automatically changes all duplicates marks. You just have to create a list with the categories or family types that have Duplicate marks, set Run and thats all!

1.First of all download the Dynamo node(find the link at the bottom of this post)

2. Create a List with the categories or family types that have the Duplicate marks

3. Connect the create list to the “Replace duplicate Marks” Node and hit Run!

Below you can find, first the link of the Dynamo node and secondly the link to the python node code:

Mechanical from scratch using Dynamo [Part 2]

Today I’ll explain the node we have created to generate ducts in Revit using lines coordinates from a cad file.

We will use the Revit API method Document.NewDuct Method (XYZ, XYZ, DuctType), which needs 3 parameters:

2 XYZ : (Autodesk.Revit.DB.XYZ) for the first and second point of the duct.
DuctType: (Autodesk.Revit.DB.Mechanical.DuctType) The type of the duct.

Mechanical from scratch using Dynamo [Part 1]

I would like to share with you a project where I’ll try to create an HVAC system from a CAD sketch into Revit using Dynamo. This is not meant to be a new procedure to design mechanical systems more than a study of Dynamo capabilities on MEP modeling.

For this I’ve created this milestones/steps I’ll try to accomplish on the next posts :

1. Model a simple building on Revit and export to CAD.
2. Sketch an HVAC layout with a supply system and a few diffusers.
3. Export the location of the elements back to Revit using Dynamo.
4. Change the sizes of the elements according to the flow needed on each room.
5. Tag all elements having in count it’s locations and sizes.
