    Beam Join/Miter Tool is finnicky

    Hell everyone! I'm a long time lurker here, and I finally decided to jump i feet first. I'm having a problem with the beam join/miter tool. It seems to work only when it wants, and of course always when it's most inconvenient.

    I have some crooked beams on our roof plan. Initially we were drawing them as two seperate beams, but it's resulted in quite a few requests for information (RFI's) from the contractor. So I went in and started to miter the beams to show that they are indeed one beam. It grays them out and doesn't allow me to miter them. I've check a thousand times to make sure they're on the same plane, aligned to grids, etc. It's absolutely maddening! :banghead: Is there something I'm missing as to why it won't allow me to miter? Please help me before I go crazy. :crazy: Any help is appreciated!

    can you provide some screen shots of the beam conditions.

    The end points... (the blue dots) have to be joined.

      Yeah. I created some screen shots, but for some reason it wouldn't allow me to upload them. But... I finally figured it out.

      This is the condition where it will not allow me to miter. It grays out the two beams I need to join.

      This is the condition where Revit allowed me to miter. It shows the little arrows and what we like to call the magical green line. Any help is appreciated!

        I am gona have to go with make sure your beams are "joined" before you try to edit the beam joins. It looks like they valley isnt lined up exactly. when you select either of the beams you get a blue dot at each end. When you select both beams at the same time you get a blue dot with a white center. When you see that blue dot with the white center you know the beams are joined. you should be able to right click the blue dot and select edit beam joins.

        Make sure your beams arent connecting to the beam passing thru. They have to be an end condition.

          I always use reference planes and "cut geometry" rather than mitre or using beam joins, its far more reliable. Of course there is a bit more mess but if you manage your reference planes as soon as you place them, name them all and trim them down to be very short to only cut thru the element you need them for its not that big a deal.

            For a mitre to work the beams must be the same type. This way the geometry of the mitre will be correct.

              Thanks everyone! I tried a thousand different solutions, nothing really seems to work 100%. It just seems to pick and choose when it wants to work. I ended up creating a bent beam family that I modeled in place. It works much better. Is there already a tutorial on here for that? If not I could type something up, I suppose.

                  I've spent a lot of time with the beam join tool and it is finicky. But the biggest requirement is that it indeed has to see a "joint" between the two beams. The miter portion is only one part of it. There are other conditions that it can do and it depends on what you want. For your condition I tend to get a reference plane in plan that is along the beam line, then place the beams while in a section or elevation with that reference plane as the work plane. Especially if you place them as a chain it seems to work better.

                  Here's some other conditions that it is useful for. beamjoin1.PNGbeamjoin2.PNGbeamjoinmiter.PNG

                    How come if you have 2 mitered beams, when a column is placed below them at the miter joint, the beam join breaks?
