Automatic Updating Electrical Symbol Legend in Revit

Electrical symbol legends are a critical part of electrical design documents and everyone wants to have a Symbols List which automatically updates to show the actual electrical symbols that are placed in a project.  That way, the only symbols that are on the list are ones that are actually placed in the model and the list does not include many unused symbols.  It is actually possible to do this.  When an electrical item gets added to the model, the symbol gets added to the symbol list.

Pricing Transition with Autodesk Software

It is that time of year that my Autodesk subscription is up for renewal, so it makes me think about the latest pricing system that Autodesk has been implementing lately.

I had been on the “Subscription” plan for years, but that name was changed to be called the “Maintenance” plan in 2016.  The new “Subscription” program is entirely different than the old subscription program even though it has the same name.  Yes, that can be confusing.

Schedule Organization Improvements in Revit 2018.1

For a long time, I have wished that there were better ways to organize schedules in Revit’s Project Browser, especially in project files with dozens of schedules.  The recently released 2018.1 version of Revit does just that and allows me various ways to organize my schedules in a Revit project file.  Different disciplines and different companies have varying quantities of schedules, so some users will appreciate this new feature more than users.

The following image shows grouping the schedules based upon working schedules and schedules that will be placed on sheets.  This particular option is created by having 2 different View Templates for schedules – one for working schedules and one for schedules on sheets.  Schedules are then grouped by View Templates.

Specify Circuit Path for Actual Length in Revit 2018

Electrical designers can now get actual circuit lengths in Revit 2018.  In previous releases, Revit would calculate the “X” plus “Y” distances plus the vertical distance in the circuit resulting in incorrect lengths.  Revit now allows you to specify a path for the circuit, which can calculate for the circuit running along walls, ceilings, etc and other jogs to account for where the circuit conduit would actually run.  Going through the process of specifying an actual path for receptacle or lighting circuits is probably overkill and won’t be performed by most electrical designers.  However, specifying the actual path for an actual circuit length can make a big difference when calculating voltage drop for large electrical equipment.

Revit Panel Schedules Not Updating

I have run into a quirky situation with Revit electrical panel schedules that I want to pass along.

When using Revit MEP for electrical design, part of the process is creating circuits and then adding that circuit to a panel or switchboard.  The Trip Rating of the circuit sets the size of the breaker on the panel or switchboard, so it is shown on the electrical panel or switchboard schedule appropriately.  If the Trip Rating is changed, the breaker size automatically updates on the panel schedule.  All is good.

The panel/switchboard schedule is then placed on a sheet for documentation/printing purposes.

The problem:  Sometimes the updated Trip Rating does not update on the sheet although it is actually updated and correct in the panel schedule.

This creates a strange situation where the information shown on the sheet is not the same as the information shown in the actual panel schedule view.

Fortunately, when the project file is closed and then re-opened, the sheet will update to show the correct trip rating (breaker) size.

Personal Section View in Revit

Creating sections in a Revit model is key to creating a quality 3D model, and that includes creating sections that are simply used for design verification.  Construction documents typically include sections, but users also use a lot of temporary sections for coordination and verification.  A problem with temporary sections is that you don’t know who created the section and the purpose for the section.  As a result they tend to stay in the model because no one really knows if they can delete the section.

I previously wrote a blog article about creating Working Sections which helps with this situation.  However, the working section can be further enhanced.  This article will address 2 key features for improving the working section:

  1. Who created the working section.
  2. Apply a user’s specific settings for the working section.

Note that this article will build upon that previous blog article.  You can find the article here.

Multiple Circuit Home Run Arrows in Revit

For many electrical designers using Revit for their construction documents, the home run arrow for circuits is an important part of their drawings.  When multiple circuits are part of one home run, the designer wants to show multiple arrowheads on the circuit leader.  This is an easy task to accomplish in Revit.
