Revit 2018 has given mechanical engineers added capability in defining Building Types and Space Types within Revit project files. Building and Space Types are used for energy calculations and it is always a good thing when Autodesk provides more opportunity to improve the energy analysis and design process.
Building and Space Types are defined in the Building/Space Type Settings dialog box accessed by the Manage tab -> MEP Settings on the Settings panel -> Building/Space Type Settings.
Revit 2018 finally fixes an awkward dialog box. The ability to quickly add tags to a Revit view through the “Tag All Not Tagged” command has been around a long time, but the dialog box for it has always been a bit klutzy. In Revit 2018, you can now place a checkmark next to the desired categories to be tagged. This makes it work like other dialog boxes and I think more user friendly. While this isn’t a huge new feature with increased productivity or capability, I really like it.
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.
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.
Autodesk is enhancing its product for structural engineers and is previewing those enhancements to Advance Steel and Steel Connections for Revit at NASCC 2017.
Following is Autodesk’s statement concerning the enhancements.
Autodesk Revit and Advance Steel better connect structural design and fabrication
Since acquiring Advance Steel in 2013, Autodesk continues to work towards better support for BIM-centric workflows for structural steel design and detailing. For instance, we have been working to strengthen the interoperability between Autodesk Revit design software and Autodesk Advance Steel software. In advance of tomorrow’s opening day of the NASCC conference, we’re happy to announce that the forthcoming Advance Steel 2018 release next month will now offer seamless consumption of LOD350* Revit models.
This exciting news means that engineers can deliver more accurate designs and bills of materials to the detailer and fabricator. And for the detailer, it means they can more quickly respond to design changes while delivering the files needed to drive steel fabrication. This interoperability will help steel detailers and fabricators take full advantage of the steel design model—a notable benefit for the industry.
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:
Who created the working section.
Apply a user’s specific settings for the working section.
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.
