I was recently exposed to an issue with electrical panel loads that illustrated what I feel are unique characteristics of how Revit circuit loads and Load Classifications affect the values that you see on the electrical panel schedule. If everything is utilized in Revit exactly as Revit is designed and intended, everything works fine. However, that rarely happens. Engineering firms create and customize families, and change or set Load Classifications which can impact the proper loading calculations.
Many companies have electrical panel schedules which display the Loads Summary at the bottom of the panel. This summary section separates each Load Classification into its own line so that you can see how much Connected Load exists for each different type of Load Classification and the Estimated Demand for each Load Classification. Those load values are then displayed as the Total Connected Load and the Total Demand Load that should include everything on the panel. The Total Connected Load is then displayed on a Switchboard panel schedule from which that panel is served. There are many different variations of how this information is displayed, but the general process is the same. Subpanels may also be involved, but the same issues exist with those loads.
In reviewing the issue, there were 2 different problems that were manifested in the panel loading. This article is an attempt to describe those 2 problems to help others understand what may be happening when load numbers don’t add up. I recommend everyone read the Autodesk Knowledge Network’s explanation of how Load Calculations are supposed to work. Read it at About Load Calculations.
As a consultant and trainer, I work with many people that are currently working with AutoCAD or transitioning to Revit. I am constantly amazed at the number of architectural users of AutoCAD that are not aware of detail components within AutoCAD Architecture. These components can be an important part of drafting the many details that are part of an architectural design office. Over the years, I have spent many hours drafting details for construction documents and I think of the advantages of having pre-made components available to me for detailing.
When a project team collaborates on a building project using Revit, it is very important that all team members maintain consistency between the different models. One of the important aspects of consistency is to ensure that everyone is designing their building components to the same coordinate relationship as the other team members. Team members will link Revit project files from other team members into their file via various positioning methods. Correct positioning is important and maintaining that positioning is even more important. It can create havoc in a project when a linked model file gets moved and building components start getting placed in positions not consistent with the linked model’s original location.
The first thing to do after linking a Revit project file into another file is to: PIN IT.
In the building design process, remodels and additions are more common than just constructing a new building. Therefore, you will commonly have existing modeled graphical objects shown in the same view as objects that are constructed new during in the project. When this occurs in an Autodesk Revit project, you have choices on how the new and existing information is graphically represented.
There are two primary methods for showing both existing and new objects in the same view. Both methods show the same information, but show them different graphically.
This is Part 5 of a multi-part series on the Autodesk Content Browser. This article will address how to add tools and tool palettes to the Content Browser.
Part 1 of the series addresses why you would want to use the Content Browser and how to get to it. Read it here.
Part 2 of the series addresses how the Content Browser is organized. Read it here.
Part 3 of the series addresses the library to which the Content Browser will look. Read it here.
Part 4 of the series addresses adding a catalog to the library and how to make catalogs available to users. Read it here.
The most important part of using the Content Browser is having appropriate tools and tool palettes contained within it. That is where the true power of the content browser comes into play as it gives accessibility to those tools deemed important to be shared with others.
