As someone that creates a lot of Revit families, I always appreciate Revit enhancements and new features that help with creating or working with families. Reference Planes are a critical component of families and Revit 2017 has some interesting changes in regards to them.
When creating Revit families, it is important to easily see the entire family model in plan view while you are creating or modifying the family. While this may seem obvious, by default Revit does not necessarily provide this ability. You may add some information, such as an extrusion, to the family and have it “disappear”. I have “been there, done that” when I added an extrusion based upon a higher reference plane and then had it disappear when I finished the extrusion. If you don’t understand what just happened, it can alarm you and frustrate you.
As I work with electrical engineers who are migrating to Revit, a common question that I get is “How do I create one-line diagrams in Revit”. One-line diagrams, also called single-line diagrams, are an important part of electrical drawings for construction documents, so it is a subject that needs to be addressed. They are a simplified method of representing a 3-phase power system that shows distribution boards, switchboards, transformers, panels, breakers, etc., with lines illustrating the connectivity of the components of the distribution system. The diagram is not just for physical construction of the building’s electrical system, but developed by the electrical engineer during early stages of design.
The problem that you run into with creating one-line diagrams inside Revit is that the one-line diagrams are generally created before the equipment is actually placed in the Revit model. The electrical engineer will design the building’s electrical system by developing this diagram, then placing the electrical service equipment based upon the diagram.
Unfortunately, Revit does not provide a way of coordinating the one-line diagram with the actual electrical components placed inside Revit, either before the electrical equipment is placed or after the equipment is placed in the model.
There are times working within Revit that Masking Regions are needed in order to hide/cover model information within a project file. There can be various reasons for this, so I won’t discuss the “why” you would do it. You will recognize the need when you confront it. However, when working with Masking Regions, it is always good to know the guidelines and rules for how they work.
Following is an illustration of a Masking Region covering part of a simple model.
Many people are now aware that Autodesk has released the 2017 version of its various software packages. There are many great blog posts about the enhancements in the packages and I really like some of those enhancements. Before discussing any of those 2017 enhancements, I thought I would post some links to official Autodesk pages for you to peruse.
Architects and Engineers that collaborate on projects using Revit will typically link their models together to see the other discipline’s design within their model. Part of that process often includes one discipline using the Copy/Monitor function within Revit to copy specific model items from the other discipline’s model into their own model. Revit has a new twist on the coordination review feature when you monitor items between different project files.
(Please note that this article only addresses the new twist and does not explain the process of linking files or using the copy/monitor function.)
If you are using Revit for electrical design, sometimes you need a piece of electrical equipment to have more than one feed but carry the same load. A common situation for this is an Automatic Transfer Switch (ATS) where it is fed through both the primary electrical system and an emergency backup system powered by a generator. Downstream panels served by the ATS will receive power from both the primary electrical system and the emergency power system.
This is possible through having 2 electrical connectors on the electrical equipment family. Each connector can then be connected to the appropriate electrical system and show the same load.
