It would be nice if Revit could create a one-line diagram automatically from the electrical panel schedule and be parametric.   As it stands, I believe all the electrical engineers have to make the diagram as a drafting view (manual sketching) and it doesn't automatically tie back to the schedule or the model data.

I want Revit to authorize the cable tray based on the number and size of cables that can fit in it.   This is similar to duct sizing and pipe sizing functionality. Show More

Hello, It would be good if there was an option in certain Revit families to prevent the geometry from being mirrored. E.g. a Mechanical FCU which only has left hand side option. Or a single socket outlet which has the switch on the left. Connected items may be an issue, however, ideally these items can be grouped and mirrored, when mirrored, the items still appear correct, e.g. switch on the left.   Alternatively, it would be nice to have a simple method of scheduling which families are mirrored.   Regards David Show More

I place light fixtures in an electrical model that is then linked into an architectural model. I have been told that fixtures in a linked model do not cut the ceiling in a host model. This creates a huge issue in our industry. I was told there were three options to fix this: copy monitor, place the fixture families directly into host model or modify the light fixture to include masking region. I have an issue with all three of these options.    Copy monitor takes the architect a lot more time to render the room correctly and doesn't make sense if I already have the fixtures in the model. I can directly place fixtures in their model because architects don't want to give permission for other firms to edit their models. I can't create a masking region because then it creates issues for other models that link in the electrical.  Show More

Adding the ability to select "Number of Phases" in the Properties Palette for the Electrical Design Analysis Tool for Revit '23 and newer.   While trying to use the Electrical Design Analytical tool within Revit '23, when entering our electrical loads for calculations they are all locked/greyed out on 3 phase power in the Properties Palette with no option that I see how to change between a 3 phase or a single phase power source.   Ex. If you enter a 120 Volt load it is always locked at 3 phase causing the calculations to be wrong, instead it would need be 120 V single phase load. Show More

Please add Hidden Lines to all categories so the built-in functionality works across all families. Autodesk neglected to apply backward compatibility, so the older categories do not have Hidden Lines by default, unlike the newer categories. Which means that certain categories are not displayed as expected, which can have significant financial implications for the projects.   Show More

I would like Revit to have an automatic sizing function for conduit systems similar to that of duct systems.   When you create a duct system, you can select the entire system and use the sizing function to have Revit determine the correct sizes of the ducts based on friction, velocity, static friction, etc.   The conduit system should have something similar so that the correct conduit size can be calculated easily.

Currently, when a circuit not yet linked to a panel is assigned to a switchboard, it is connected to the first available phase. For example there are 4 outlets being connected to Panel 1, one per group. (Group1@Phase A, Group2@Phase B, Group3@Phase C, Group4@Phase A) When selecting the 5th outlet and clicking the 'Power' button, it will automatically be assigned to Panel 1 as  group5@Phase B. When the circuit is transferred, with the Panel selector in the Ribbon, from one panelboard/switchboard to the other, its phase is kept. So Group5@Phase B from Panel 1 transferred to Panel 2 will become Group1@Phase B. It would be helpful to have an option to choose between: "Reset the Phase assignment to the first available or specific phase" and "Keep the previous phase". This preference should be remembered. This might be a checkbox within the "Modify | Electrical Circuits" status bar as shown in the attachment. It now can be done by disconnecting the circuit first, which introduces an extra step.

At this point in time the only supported wire sizing in Revit is AWG (American Wire Gauge). This is stopping electrical engineers using the metric system from using the power of the Revit electrical functions. On the Autodesk help site there is a full article on with the tables for the correction and impedance factors for the different wire sizes known in the USDM(United States domestic market) https://help.autodesk.com/view/RVT/2019/ENU/?guid=GUID-0F801DCD-18CD-4B7A-A64F-D4D9E8A4CEA9#GUID-0F801DCD-18CD-4B7A-A64F-D4D9E8A4CEA9__WS1A9193826455F5FF-4F6D1F1D11D24BE3E03C1B   If these tables would also be implemented for metric sizing, then this would allow for the use of the following: - The parameter voltage drop can function properly    this does not function at all when working with any sizing table then in the help article above. - Use the wire size functions as intended    because the voltage drop parameter does not work the calculations made when upscaling wiring due to the length of the wire does not function at all.    the sizing will automatically adjust when the rating of the circuit was to change  - use wire types as intended   there is no way to use the wire types as intended because wire size does not work, the only workaround is to use a text parameter to display the cable or make a list of all the wire type and wire size combinations with a list of hundreds of wire types as a result.   With the BIM way of thinking this would keep the information combined in Revit, and would minimize the chance for mistakes.       Show More

Within our MEP office, it seems one of the primary challenges we've had with the integration of Revit is the lack of electrical functionality when it comes to project phasing. Various components of this have been suggested over the years, but it seems like the ask could be simplified as follows:    Provide project phasing for electrical circuitry. In the real world, circuits existing in a place and time like all other model geometry, so it doesn't make sense that they are handled like annotations/analytical calculations that exist only in the scope of work.  Allow for use of phase filters on electrical panel schedules.  This allows for a designer to display and existing and revised condition. This is typically displayed on every project that involves modifying the loads associated with a panel.  I am aware that there are work arounds using Excel or Drafting views, but this is definitely a hang up every time we train a new electrical drafter/designer.  Show More

We are beginning to receive project requirements with increased LOD requirements and model deliverables, but it is proving to be impossible to deliver on these requirements due to lack of functionality in Revit's electrical circuiting capability. One primary shortcoming is Revit's inability to model double ended unit substations in a main-tie-main configuration. The primary disconnect section, the transformer section, and distribution sections can all be modeled individually and circuited together, but there is no way to tie both distribution sections together to share load. You would expect that a second connector added to the distribution section family could be circuited to an additional connector of the other distribution section, but this results in an error message stating that, "There is a circular chain of references among the highlighted elements." It would be great if a new variation of circuit or electrical "Tie" connector could be created that could take the connected load of the 2 family's, sum them together, and pass them upstream to the primary connector. See PDF attachment for additional explanation. Show More

The Cable Tray as a system family works great from the sense that we can define various families for different fittings.    The Cable Tray as a system family doesn't work so great when it comes to representing the geometry accurately. What I'm seeing is the cable tray size, is what we would consider a nominal size. a 12"x4" tray (in my case, Panduit FiberRunner), is the available space within the tray. The overall dimension is actually closer to 13"x4.5". However, unlike conduit, the size may not be centered with the tray itself. For the Panduit FiberRunner, the difference in height is added at the bottom, and the difference in width is tapered outward at the top.  The snapshot below shows what I'm referring to.    What I'd like to be able to do, is to define a profile for the Cable Tray System Family, and still maintain the ability to use the functions for creating bends, tees, crosses, reducers, and unions.    Show More

I have been in contact with Autodesk support about this.   In Revit 2020 we have an Electrical Equipment family which represents a Data-switch. This family is set to 'Part type' 'Other Panel'. This family is loaded into a project. From this project through 'Edit Family' we change the 'Part type' to 'Switchboard'. This adds several extra parameters to the family like 'Max #1 Pole breakers'. We load this family into the project so the parameters are available in the project. We change the 'Part Type' back to 'Other Panel' and reload the family into the project. This will keep the parameter 'Max #1 pole breakers'/'Max number of circuits':   This limits the number of data connection that can be made on the data switch. This works fine for Revit 2020. In Revit 2021 the 'Max #1 Pole Breakers' has been replaced by the 'Max number of circuits' parameter. If we use the same methode with this parameter you can connect more than the set max number of circuits for the data switch:     Autodesk concluded with: "There currently indeed is an inconsistency as "other" panels could not be limited using some kind of "Max number of ports" parameter. As Data switches don't have breakers having the "Max #1 Pole breakers" parameter in a data switch is not supported in Revit. Using the hack that was working in 2020 was a really clever workaround (love it) but is currently not a design scenario in the current version." Since we need to control the maximum number of connections to any panel i would like to suggest this to be implemented. Show More

Here in Australia we are modelling more and more 'sweeping bends' conduits, mainly due to the new NBN (National Broadband Network) Revit does not allow us to draw a conduit with a radius in one go, we have to attach bends etc, this does not work in this scenario, we need to have one element but this is not possible without drawing an 'in place' family each time, which is totally unviable due to time constraints/changes. Surely it would not be too hard to draw a conduit from point 'A' to point 'B' as you would a spline in CAD? Show More

Can we have the option to sort/group the Panel Schedules section of the Project Browser?   It is difficult and time consuming to scroll through a list of 100+ panel schedules on our multi-floor projects (i.e. an 11-floor hospital).   Primarily, we would like similar functionality to the Schedules/Quantities section where we could Group by Leading characters.    Having the ability to group by associated panel element's Level would be nice too, but I could see this possibly not being available...  Having the ability to assign Project Parameters to Panel Schedules might be a good workaround for this too...

I created an idea already for this and piping, but forgot that is is not just piping. http://forums.autodesk.com/t5/revit-ideas/pipe-duct-demolition-keeps-system-designation-and-stays/idi-p/6340415    All elements should keep the connection to their original system, or somehow maintain the relationship to the original system designation.   Within electrical if you demolish something that element is removed from the panel. If you have multiple phases and show elements on the panels at an early phase, you can't do this. So you have to just work around the phasing for those elements. NOT ideal.   If this was handled a bit differently then we could still use the native Revit systems and the native Revit phasing tools.   If a wall can infil after a door is demolished, I'd think something could be done about the phasing on the MEP side of things.

currently when you try to schedule elements that have different values for a particular parameter, Revit changes the cell to appear blank.  Revit should allow the schedule to list the different values.  Could be by default or as a check box option per field.       Show More
