    Surface mounted electrical fixtures guidance

    Hi, first post on here so I'll introduce myself.

    I work for a small catering equipment distributor in the UK. I have built up a catering equipment library to the point where I can produce layout drawings, elevations etc...

    The next challenge I am faced with is mechanical and electrical service drawings. I have not had any training on revit MEP so I am currently exporting the layout from revit to autoCAD then drawing single line MEP symbols to provide my client with a drawing.

    When I attempt to add electrical fixtures from the autodesk library to my model revit will not recognise the walls. It is not recognising the walls because I am working off a linked model. I link the architects model into my project to keep the file size down.

    I have drawn and added the appropriate labels for a single switch socket outlet. But I am struggling to find any guidance on creating surface mounted (not wall mounted) fixtures. Has anyone come across a tutorial of this description?

    Thanks







    PS, I apologies for any misuse of revit terminology - I'm no expert.

    My advice, (Which not everyone agrees with but is based on 5+ years experience with MEP projects) is to only use Level hosted fixtures. So they are just placed on the floor plane and with an offset height. Its not hard to align fixtures with the wall when you place them.

    Placing fixtures on the wall so that they move with the architects changes might sound like a good idea... but in practice I think it is much easier to be able to clearly see which fixtures are not aligned with the walls and re-align them, than have to find/manage which fixtures have moved or not, which fixtures have lost their host wall etc..
    Level based fixtures are also much easier to copy from room to room and floor to floor, saving a lot of time.

    If you really do need to place a fixture on a wall/panel/cable tray etc. this is still possible. You can edit the family and check the 'Workplane based' box. Then you can place the family on any face too.

    Heres an example.

    Thanks, Darius. I searched 'create face based family' and found what I was looking for. In hindsight, I think I was focusing my search on 'electrical fixtures and components'.

    My aim is to place various electrical components within my kitchen model with the intention of producing elevations like the attached, showing electrical outlet heights, avoiding clashes etc.. elevation.pdf

    In the plan view electrical components will be indicated by use of symbols (attached).

    I have modeled my face based electrical outlet and drawn my symbol for plan view.

    I have since discovered that annotation symbols cannot be attached to a face based family – it’s got to be a wall based family.

    I link architect’s models so wall based is not an option. I have tried the copy monitor method of converting face based to wall based but it was unsuccessful.

    Annotation symbols can be attached to a face based familiy: I posted a solution here:
