    Modeling Roof Deck

    I know this is going to sound like a stupid, simple question...

    ...But, how the heck do I model in just plane old simple metal roof deck?

    I am having a heck of a time. I tried starting with a roof under the architect tab but I just can't seem to get it to work. Plus I have a sloping roof, and I do have RP for the slopes, but UGH!! I just don't know how and when I search for roof deck not much shows up (especially for a beginner), and I need it from a new revit user stand point (yes, I admit it - I give up, I need help!)
    Yep - It's me Again, and Again, and Again.......

    Easy. Use the roof tool like you did previously. You will go into sketch mode (drawing pink lines). Sketch your roof. Now, you'll either see some triangles on the midpoint of each line, or not, depending on what settings were on by default. I think it should show them. Those tell you that that particular roof edge defines a slope.

    For a flat roof, select all of your roof sketch lines and uncheck the "defines slope" parameter in the properties. Hit the finish button, and your done. You may have to put it on the correct level, or define an offset in the properties to get it at the correct height. All of that can be done afterwards.

    To give it a simple slope, select the roof. Hit the edit roof button. This will put you back in sketch mode. Select the roof edge that will be the gutter edge. Check the defines slope paramater, and give it a slope. 3/8" for example. Finish the roof. Your roof now has a slope.

    For gables, do the same thing for 2 opposing roof edges. For hips, same thing for all 4 roof edges.

      Dan, I would like to disagree with you slightly. Instead of using the roof tool, use the floor -> structural floor and in the floor structure, you can select Structural Deck [1] as your Function, then it will let you select a Deck Profile and Deck Usage. Other than that, agree with Dan on everything else. Oh, and I like to use the slope arrow for non-Flat roofs (greater than 0'-2"/1'-0") and I model gables as two separate roof decks.

        Ahhh, nice! I wish I would have known that earlier. Now I need to redo my suspended concrete floors so I can show the profile automatically. :thumbsup:
        If he needs to schedule his roof, then that will mess it up, won't it? I mean, it's technically a floor. I don't schedule mine, so I'll be using it for sure.


        Defines slope just seems a little easier for single slope roof (to me).
        Why do you model gables as two separat roofs? Just wondering.

          We don't schedules our floors with Revit sadly, but you can do it. It will just show up with your other floors too.

          Defines slope is easier, but our architects like to change their slope a lot and they almost always change their boundary to suit, which is the reason we do two separate roofs. If it was up to me, I'd use just a single floor. =\

            I just tried doing the floor with a metal deck but it will not let me. I set my cnaopy rp as the reference plane and then opened the second floor to draw the floor (deck) in and this popped up:
            The work plane of this view cannot be used for this operation.
            This operation should be performed in another view or the work
            plane of this view should be set to a Level by using work
            Plane command.
            What does this mean and what now?

              Try this - name the RP if it's not already - go to your second floor and set the RP active - then draw your floor.

              I think it's an order of operations issue. You set the RP active before you went to the level.

              Just a WAG though so no promises!

                Actually, you can't place floors on a sloped RP. You have to either use a slope arrow or have one of your lines define the slope. I normally use the slope arrow. Then once you have your roof at the right place, align your named framing RP to the bottom of deck.

                  OK - Floor in with a slope arrow.

                  Why can't I align my deck to the named RP?
                  It is at an odd angle, that would be the easy wasy to do it, but it won't let me.
                  So how can I do this?

                    The RP and the roof must be parallel. Otherwise, you'll get the "can't change the plane of a roof or floor" warning.
