One good example would be creating four or five different VAV connector types so that when the load changes on one of the connector types, a single change to that type parameter updates all of the loads across the entire model. Some of the parameters may apply to multiple families as well.Ĭreating multiple types for a specific family element allows you to change those parameters across your entire model. Note that you might need more than these for your specific project. These parameters should include load (VA), description, load classification, voltage, default elevation, cost, type mark, manufacturer, and comments. The parameters used in your Revit families should be mostly type parameters. You can set different instance parameters for each instance in the project. Instance parameters, on the other hand, can vary for each instance.
Change the value of a type parameter and all instances will update as well. When you place the family in your project, all instances of that type will have the same type parameter values.
So what’s the difference between the two kinds? Type parameters are consistent for each instance of that type in the project. Understanding when and where to use each kind of parameter is critical for an efficient workflow. Revit has two kinds of parameters type parameters and instance parameters.
When done throughout the course of the project, this information is simple to provide. Typically, this information takes a long time to collect you need to add up all the receptacle loads, lighting loads, largest motor, as well as heating and cooling loads. The utility company uses this information to size the transformer at the service entrance. These classifications will be put on your panel schedules and are useful when filling out utility letters at the end of a project. Load classification in Revit segments your loads into different classifications.
Here are my top 5 tips every electrical engineer should know to get really productive with Revit. Over time, I learned some tricks that made modeling electrical systems MUCH easier.
Yet I made progress learning the software by starting on the surface and mastering the basics. In a way, I found Revit to be a lot like Excel – there are deeper and deeper levels to it. Getting started took some effort and I tried to learn just one piece of the software at a time. It’s a powerful tool but it can also be intimidating. It seemed that with Revit, if you can imagine it, you can create it. First, there are all those buttons and options. When I first started using Revit, I found the software to be overwhelming. In this post, he shares five of his best tips. As you’ll see, Dillon has a lot of experience with Revit and has learned a bunch of tricks that help him work smarter and faster. This is a guest post by electrical engineer and Revit expert Dillon Mitchell.
