Using Revit, Dynamo and Navisworks for better MEP Coordination


By Armundo Darling

Let’s take a look at a clash detection workflow between Revit, Dynamo Studio, and Navisworks Manage that can help improve design optimization and efficiencies in building design coordination.

This workflow streams clash results between MEP and structural designs using a live link between Revit and Navisworks with Dynamo, and improves clash detection throughout the Building Information Modeling (BIM) process.

Clash detection can be conducted on building elements like walls vs. ducts, walls vs. pipe, and beams vs. pipe in a Navisworks coordination model containing MEP and structural design models from Revit.

Using Dynamo within Revit, you can create and run a script to perform a background clash test using the Navisworks core, and return visual feedback in the active Revit project with Clash Indicators and 3D Clash Views.

Running the Dynamo script, you can change the Clash property of the analyzed elements, create separate sectioned 3D views showing each clash, and place an indicator (by means of a 3D arrow with attributes) in the Revit model at the clash points.

Working in the 3D clash view in Revit enables you to quickly identify the clash and resolve it faster. When you make changes and run the script again, it removes the previous clash views and indicators, generating new views and indicators for the new clashes.

Changes that are made in a linked model can be viewed after it has been saved and reloaded into your project. When you rerun the Dynamo script, you will notice that the clash with the linked model has been resolved. The clash list and the Navisworks coordination model will automatically update.

Navisworks also gives you the ability to change the status of clashes to Resolved, Approved or Reviewed.  You can also add a comment to keep team members informed regarding the clash.

Dynamo enhances Revit as the clash information can be added directly in the Revit project to improve building design coordination.

Take a look at this building design coordination workflow video for more detail.
