    Rib & Block Display

    Dear Forum Members

    I'm rather new to Revit specially family section but I have to solve the following:

    To create a family which can show the Ribs & Block layout of a precast slab(see attached file) by inserting
    the family into a project and inserting the length and width of a room and it generates a simple slab layout.
    I have some fair knowledge of 'arraying' feature of Revit but battle to understand the array in two directions (i.e. x and y).
    Any help in this regards I would appreciate very much.

    Thank You

    You must make an array in X with the block and create a block line. Then take the block line and make an array in Y with it.
    At least this is what i know

    By the way...
    Arrays are not a good idea. They consume many resources.... i think

      I believe a beam system would be a better option than an array, although I would defer to the structural folks.

        This is just a hollow-core slab, which does exist in the revit Library already.
        Although it does not draw each individual brick, I would ask what you hope to gain by doing that?
        Are you planning to list every brick needed to supply to site? I suggest that can easily be handled in a table with a formula rather than trying to over complicate your model for little gain.

        example. 1 brick = 25cm wide x 50cm long x 12.5cm deep (this may not be the actual dimensions, Im just throwing numbers for the sake of the exercise) Now you have a volume that you can divide the total volume of your slab which revit will calculate for you in about half a second. (or rather total volume/block volume = number of blocks required)

        Or 1 square meter has X number of blocks ....

        you are not gaining much by overcomplicating that, at least not that I can see

          If you want it all in a single family you'll need several layers of nesting - the first is the individual segment that will be repeated, the second arrays this segment in one direction, the last array the arrayed segment in the other direction - yes, arrays are process intensive but if you need it, you need it

            Arrays are fine. I've got arrays everywhere and there aren't any issues.

            Having said that, in this case I wouldn't bother. I would use Structural Framing members for the whole thing: one member that is the blocks, and one that is the rib between the blocks.

            Putting that all in a component as a bunch of nested stuff isn't getting you any added value. You are just trading time to model individual members for time fighting with unneeded parametrics to make all the conditions work.
