Two questions are often raised about our MEP Hangers tool for Revit, usually during training sessions or a short time after beginning to use the extension. These popular questions are related to each other and have to do with hangers for HVAC services that have insulation and how to transfer information from MEP elements to hanger families in your project.
Q: "How do I put hangers on a duct or pipe over insulation? And how do I make it so hangers that I create myself will account for insulation too?"
A: You can control this using two parameters inside the hanger family. What you need to do is create a parameter that copies the thickness of the insulation from the MEP element to the hanger family and another parameter that controls whether the insulation thickness is added to your hanger size. Here's how to make those parameters.
Step 1. Create a parameter that copies the "Insulation Thickness" value from ducts or pipes into your hanger family. Use our MEP Hangers Revit extension to do this because it lets you copy different parameter values from interconnectable MEP and structural elements into the connecting hanger family. MEP-element (host)-related parameters are transferred under the “Model Properties” parameter category.
