One-Line Diagrams in Revit

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.

Masking Regions in Revit Projects

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.

Autodesk 2017 Release Information

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.

Revit Copy Monitor Item Change Notification

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.)

Revit Electrical Equipment with 2 Feeds

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.

Revit Schedule Title

Wouldn’t it be nice if you could easily give a Revit schedule any view name that you want and have a different title appear at the top of the schedule on a sheet?  You can!

By default, the View Name parameter in the Properties of the schedule will appear as the title for the schedule.  As of Revit 2014, you can edit the title to be what you desire, regardless of the view name.  That allows you to name the schedule whatever you desire to aid with project browser organization and providing a good description of the schedule’s purpose.

Autodesk’s New Terminology for Licenses

As most Autodesk software users have learned, Autodesk has modified its method of selling the various software packages and how users pay for ongoing usage of the software.  I won’t go into those actual methods as they are well documented at Autodesk.  However, since “words mean things”, I am posting this notification from Autodesk.  When you see information from Autodesk, it is important to know what they now mean as the old terminology we previously used may not mean the same thing now.

Here it is….

Dear Autodesk Customer,

On February 1, 2016, we are making some simplification changes to our subscription offerings by:

  • Changing the way we talk about our offerings
    • Everyone with a Desktop Subscription or Cloud Service Subscription will simply be subscribing to an Autodesk product or service—rather than purchasing a “type” of subscription—and will be referred to as a subscriber.
    • Network licenses will also be referred to as multi-user access (shared by two or more people).
    • Standalone or named user licenses will also be referred to as single-user access (used by one person only).
    • A “Maintenance Subscription” will be called a maintenance plan—and to accurately distinguish these customers from subscribers, they will be referred to as maintenance plan customers.
  • Consolidating our Global Travel Rights policy
    • If you have purchased your software in your home country you will be allowed to access and use your software while traveling worldwide for the term of your subscription or maintenance plan.
  • Updating our terms and conditions, effective February 1, 2016
    • To reflect these simplification changes, and other related changes
    • Pursuant to section 8.9 of the Autodesk Maintenance Subscription Terms and Conditions and Autodesk Desktop Subscription Terms and Conditions, those terms and conditions are being replaced by the new maintenance plan terms and conditions and subscription for single-user terms and conditions which will go live in early February here.

If you have questions about the new terminology or changes to our Global Travel Rights policy, contact your Autodesk Authorized Reseller or your Autodesk sales representative.
