    Electrical imitating AutoCAD?

    Good Morning,

    The dilemma: I know little to nothing about electrical work. I haven't even ventured into that wading pool in Revit.
    I was told the electrical person at our office can get along fine in Revit. We use a library supplied to us by an add-on in Revit and I fear the electrical person has done nothing more than pasting relevant symbols into Revit.:crazy:

    I see many impressive looking symbols all over the place in the model and it all looks pretty enough but my first clue is the connectors associated with these symbols. None of them are connected if I run the Show Disconnects in Revit.

    I stumbled on this problem when someone he was training came and asked me how to show a wiring run in the Revit model. An item connected to a local DB and all the local DB's (about 5 of them) wired to a central box in the passage?
    I may be oversimplifying the request somewhat.
    He wanted to know how to draw the lines in Revit and in my experience one does not simply draw lines in Revit.
    Is this visually possible in the Electrical discipline in Revit?

    I know what I can expect to see in Mechanical and Sanitary disciplines as well as the information that can be obtained, but what should I expect to see in Electrical? How much wiring detail should there be?
    I'd be most appreciative of some screenshots and if you have time, a little explanation.

    In short: Looks pretty, does nothing and has no value, should have been done in AutoCAD.

    Ciao for now.
    Say something interesting....

    Its under Systems -> Wire.

    But actually I think its normal to not connect all the electrical fixtures. You can associate an electrical fixture with a control/power panel (edit panel system, add to system) and its normally not required to draw every single wire, just cable trays. (According to my electrical colleagues, I avoid the side of things too...)

      I dabble in electrical, and I show the wiring for each circuit with a tag that shows what panel and circuit number. It's pretty easy once you do it a few times. You can either draw the wire manually (not a line, but a wire), or you can highlight the entire circuit (by hovering and tabbing), then choosing "arc wire" or "chamfered wire" in the ribbon. I use both methods because it never puts the wires exactly where I want them. So I'll delete a few and add them manually. Here's a screen shot and a screen shot of my panel schedule.

      Now, I'm not an electrician nor am I an electrical engineer. That being said, I deleted all the load info on my schedules. My buildings are small and my electrician knows what he's doing. It's never been questioned by the city in the 20+ years I've been doing this here (CAD and Revit). You may need that info. Just FYI in case you noticed it missing in my panel schedule.

      Also, once you tag the circuit, if you need to move it, you just move it in the panel schedule. It will automatically update the tag so it always references the correct circuit. In my opinion, that's worth the hassle by itself. That saves a lot of time changing circuits manually and eliminates the mistake of missing one.

      Oh, all symbols are from the OOTB revit library. On my own families for equipment and such that I created myself, I just added an electrical connector (or multiple ones if the equipment has multiple connections), set it to the correct voltage, phase, etc. and that's it. When it's in the project, you just click it, hit the Power button in the ribbon, select a panel and you're off to the races. (same thing with receptacles and such. You have to power them up first and select a panel prior to doing the circuiting).

        I'm electrical

        everything dzatto said :thumbsup:

        it is not terribly easy to just MODEL electrical systems

        you have to have a general understanding of how the systems work because revit will not let you wire things up clearly wrong

        I would suggest you show him really the amount of info you have once you do circuit..I'm working with a new group and we are showing lighting controls and circuits in a totally new way

          Thank you guys, this confirms my suspicions and shows how it should be done!

          Ciao for now.

            I am an MEP trainer. I'm struck with a really hectic problem with panel scheduling.
            I added electrical fixtures and DB. Assigned proper voltage and distribution system to the fixtures and DB and made circuits and tagged wires. Everything go well except the panel scheduling. I have done panel scheduling earlier with my old computers. Now when i create panel schedule, Revit gives a warning "You have one or more loads connected to this panel that are not displayed in the panel schedule. Add the load classification(s) to the associated template to report this information in the Loads Summary." I went to Electrical Settings, checked demand factors. Then went Manage--> Edit Templates--> Set Template options --> Load Summary.Then added all the load classifications into scheduled loads. Then again opened the already created Panel schedule from Project browser. Its not updating. Head ache...Nothing turns up..

            Please please please help.... Hearty thanks in advance.
