    lt. gage metal roof truss

    does anyone have anything similar to the attached? I created one months ago for another project, but it's really rough and doesn't flex.
    Just wondering if anyone else has a better one that I can look at and reverse-engineer that might help me be able to make mine better.

    Not exactly the same thing, but maybe you can use it to reverse engineer anyway?

      oops! we're having issues getting our 2012 up and running.
      (Seems we still need ADT2006 and the NLM for 2012 doesn't want to play nicely.)

      Was this a family in the Revit Libraries?

        Leanne what exactly are you trying to do with your truss family? Did you want a parametric truss? or are you trying to control the framing members?

          You might be able to find something here.

            This truss is a Mansard Roof Truss. It's not designed by us (the structural engineer; ) it's designed by the Light Gage Truss people. What I clipped in the post above is just drafting lines, used to show the general configuration of the truss. It may, or may not be, finally constructed that way.

            Now, my engingeer says, "If we have the truss modelled, that would help the Architects to see the design intent at the Mansard Roof." So, I'm going to end up modelling the truss(es.)

            Like I said. I made one months ago, but it was the same type situation. Since we weren't designing the truss, they didn't want me to model it... but the Architects needed to see it. SO, I created a dumb, truss family; static with no flexibility in regard to span or height.

            I'd like to make a better, smarter one in as little time possible.

              Luckily this family is a old one, believe it must be a v2010

              (Opened it before I uploaded it, and saved it accidentally in v2012)

                Thanks Klauss. I think that's about where I started with my disfunctional truss.

                  You can make the truss with ref lines. then get the controls the way you want them with that and add symbolic lines to the ref lines. top cord, bottom cord... ect.

                    The problem with the previous example is if you have the roof level set and you increase the span the top of the truss changes, which might not be what you require a lot of the time

                    If you are doing a lot of this type of thing, there are a few add ins out there that work pretty well and create the truss layout based on your roof model. I would definatly look going this way if you are modelling hip trusses etc.

                    Otherwise forget making a do-it all parametric truss, and just make 5 or so options that work well with easy to use parameters

                    One tip I would give is, look at using a profile family for your sweep, that way you can change the size of the chords, and even substitute a different profile for cold formed steel etc as you go into more detail

                    The only way to get into these things is to have a go and break it a few times, unfortunately trial and error is the best way to learn
