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.
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.
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.
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.
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. Continue reading →
Autodesk has just released the Revit 2016 R2 update to users that are on the subscription program (both maintenance and desktop). Autodesk has started providing these R2 releases mid-year and can include significant improvements. While there are reportedly 25 updates in this release, there is one that I particularly like as a user working on a model with multiple other users. That is the ability to unload a Revit link on a per user basis.
Prior to 2016 R2, if I unload a Revit link and Save to Central, the file will be unloaded for other users when they Save to Central or Reload Latest.
Being able to unload a Revit link on a per user basis means that I can unload a linked file and I will be the only user affected. I can save the file to central with the file unloaded and when other users Save to Central or Reload Latest, their version will still have the link loaded.
There are definitely times when I want to increase my Revit’s performance and memory usage and I don’t need a loaded link throughout the day, but I can’t unload it because others need to have the link loaded for their purposes. You can really annoy other users by unloading a link that they want to use or see.
Buildings often have portions that are created at an angle to the main portion of the building. When this occurs, we want the construction documents to show the angled portion at right angles to the sheet to make effective usage of the sheet space. Scope boxes provide us with a very easy way to address this issue.
Scope boxes within Revit are also an excellent method of having multiple views of the same area show the exact same portion of the building in each view. This is helpful for consistency in showing a wing the same in a Furniture Plan, Dimension Plan, Occupancy Plan, Code Plan, Framing Plan, Roof Plan, Power Plan, Communications Plan, Lighting Plan, HVAC Plan, Piping Plan, Sanitary Plan, etc.
When you have many electrical devices, light fixtures or other items in a Revit project file, it is easy to miss one getting placed on a circuit. While un-circuited devices will display in the System Browser, it is nice to be able to have a quick visual check on a plan view for any of them. We can do this through creating a custom View Filter. The following image shows the impact of using a filter to show un-circuited items.
Electrical panel schedules are a very important part of designing and documenting the electrical portion of a building project. The electrical panel schedules help with designing the electrical system by showing the power requirements on the panel to the designer and allowing the designer to spread the power requirement across the poles of the panel. It is also useful for showing the electrician how to circuit the items assigned to the panel. Those 2 different purposes may involve showing slightly different information on the panel schedule. In addition to that, the facilities manager may even desire to see different information on the panel schedule.
Most building projects created within Revit will utilize linked files from other disciplines to show the various components within the building model. When this is done, it is not uncommon for users to desire to see the other disciplines at a different detail level than their own. This may be the MEP engineer wanting to see a Fine detail level in their view, but only see the Coarse level of detail in the Architect’s model. It may also be the Architect desiring to see their model at a Fine detail level, but see the Electrical Engineer’s electrical devices with a Medium detail level to show electrical symbols and not actual electrical element modeling.
Regardless of the reason, it is definitely possible and even easy to have linked Revit models show different detail levels on a view by view basis. This means that each view can be set differently per the needs of the view. Also, each different Revit link can have different detail level settings from the other links within a view.
My last article addressed how to create Working Section markers that are visibly different from other section markers. (Read the article here.) This is great for knowing which sections are not meant to go on a sheet, but it doesn’t keep the section marker from displaying in a view or on a sheet. When I have a working section, the explicit purpose is that it is just for my model review and should not be seen on a printed view. This article will address how to set up a view filter to keep the Working Section markers from displaying in a view intended to go on a sheet.
As I work on building projects inside Revit, I like to place sections in my model for continual design review. These are sections that will never be placed on a sheet for construction documents, but are there just for my usage. This is a very common occurrence and utilized by most Revit users, so I am not unique in this practice. When providing Revit training, I always recommend usage of sections for this purpose.
When placing sections, I like to know specifically which sections are for my usage and which ones are intended to be placed on sheets. Therefore, I have a special section type used specifically for this purpose so that I don’t get confused (or anyone else looking at the views in the model).
