    Metal Deck Profile at Supports.

    It is great that we can add a profile to a floor within Revit to show metal deck in section, but what use is it if it isn't accurate when it comes to producing details?

    Hopefully I am missing something here...

    The attached images show.

    1 - The default appearance of the metal deck in section at a Steel support.

    2 - The appearance of the metal deck at the steel support when I have added a cantilever to the deck.

    3 - What I actually want to see, what the contractor wants to see, and what the Metal Deck contractor wants to see.

    An opaque filled region looks terrible and goes against the idea of modelling.

    Adding a cantilever to the deck also looks terrible.

    Does anyone have an idea how to achieve a deck edge as shown in image number 3?

    Note - the images uploaded in reverse order, so view them from right to left..! :-)

    Are you using live cuts? Are you drawing with Detail Components?

      As I said above "It is great that we can add a profile to a floor"

      I am not using detail components, Revit gives us the option show the deck profile within the modelled element, so I see no reason to use 2D components if I can help it.

      The images I attached were live cuts through the model, every element was modelled, no detail components used at all.

        I have had so many issues with doing live cut details, I don't use them at all. I found that I would spend too much production time trying to get my model to display exactly what I want only to have to change it and track it every time anyone did anything to the design. We now have a typical detail library and it saves us a ton of time and give us the flexability to display exactly what we want to convey in our details.

        Others may be able to advise you better on what you are trying to accomplish. I would recomend rethinking how much "Information" you need to get out of your BIM model.

          I'm afraid I have to disagree, standard details are no good for a project specific detail.

          If the model is constructed in the right manner detailing in 3D is much quicker than 2D.

          I have gone as far as modelling nuts and bolts on steelwork connection details in 3D.

          A section that is live with the model can only be a good thing.

          The only time it becomes a problem is when Revit can't do exactly what we want it to do.

            It only took me one time, that the Architect/Client re-designed 1/2 the building at 90% CDs to make me never used live detail references again. Simple model changes can have a profound effect on your details, and their placement. Even a simple thing as moving a grid line 1 foot will make changes to your live detail references, something that you would not have to address with drawn views. Plus with drawn references, non live, I have the flexibility to make that detail display exactly how I want it too.

            I understand your frustration. I wish you the best. Hopefully someone else can address your question more satisfactorily.

              Revit is essentially only applying a 2d detail to the slab profile, if you play around a little with the profile family, you will find it is simply arraying the profile family from one side of the slab at distance that matches the width of the profile

              Doing what you have attached in the image will be correct for that location, but what about the other end of the slab panel? Somewhere the decking will need to be cut. If you want to model metal deck, you really need to use some sort of specific family. But that is really over the top of most cases

              Unfortunately, the best method at this stage is masking over the slab profile. But that doesn't mean you have to use a masking region. I would suggest creating some detail components that you can simply drop in. In the example you have shown, why not create a component that has the timber blocking built into it?

                I thought as much, I was hoping there was a way to force Revit to manipulate the deck at the supports, it would be good to be able to select the supports and have Revit automatically adjust the array so there is a tray at each support, then just equally space the other trays between supports.

                We don't design the deck but need to have it shown correct in the details.

                Basically the ability to add this profile to the floor system family has little use at all.

                I do feel that creating detail components to solve this problem kind of goes against the idea of building and using a model. Even though this profile is nothing more than a 2D representation within the floor that is only visible in section cuts.

                  Its defiantly a wishlist item, you can already do it with model hatch patterns, all we would want is the same sort of functionality here. It would defiantly be worth putting forward as a future request

                    I think I will add it to the wish list.

                    Keep up the good work with the blog Ben!

                    Cheers

                    Update - I would post this as a wish list item if I could access the wish list on AUGI.

                    Strange.
