    Dropped GWB Soffit joints question

    I found this interesting question, by "Octavio2" in another forum. I thought it would be good to post it here, too:
    __________________________________________________ ____________________

    "I created a dropped ceiling gypboard soffit with a vertical Soffit wall of 5/8" GWB on one side of 3 5/8" Metal Studs and with a horizontal compound ceiling of 5/8" GWB on 3 5/8" Metal Studs. I joined the vertical Soffit wall and the compound horizontal ceiling using the "Join Geometry" icon, and they join, but in the detail section I see that that the vertical and the horizontal gypboards do not meet to the corner.

    What needs to be done so the two layers of gypboards "fillet" at the corners?

    Thanks in advance."

    Edit Cut Profile, in the detail section, to edit the material hatching. Even making the ceiling run to the outer edge of the wall, and setting the walls base 0-0-5/8" up and doing join geo, it still wont clean up perfectly without Edit Cut Profile.

    Its a RIDICULOUS PROBLEM until the Factory gives walls/ceilings/roofs/everything join options and end conditions and top and bottom PLUS the ends.

      I made a test, and this is my report:

      I created a wall and ceiling with the specs provided. After I placed them at a certain height to meet exactly at one point; and after using Join Geometry, I got the result shown on the first image in my illustration. Then I moved the ceiling a short distance to the left. I just moved it, ignoring the warning about unjoining. Then I moved the ceiling to the right, but not to the exterior corner of the wall but to the interior corner of the wall's gypsum layer, as in the third image. Now wall and ceiling joined correctly.

      See illustration.

        Interesting solution. Im not sure i could get everyone to move the ceilings all twice to gte them to clean up, but that is fascinating. If you move the ceiling, will it clean up on two sides? (That wall, and one perpendicular to it at the edge of the ceiling?)

        Its great to know theres a way, but id probably just go with the Cut Profile.

          Well, yes, moving the ceiling might have some issues, because if we move the ceiling towards one side, probably we end up with a gap on the other side. Also, I see that if we move the wall instead, in a similar way as shown in the illustration, we get a clean join, too. The trick seems to be to join the elements, but have them meet at the interior corner point of the wall's finish layer. Or, sketch the ceiling so that it doesn't go to the outside of the dropped wall but just 5/8" less on each side (in this case).

            Well, the trick has to be the actual MOVE, after the join. We sketch our ceilings so they align with the interior face fo the finish layer of the wall (the gyp), but they clean up with all but the corner (5/8"x5/8"). Although- now that i think about it, i believe they are different materials of gyp in our template, so that makes sense. Theyre never going to join correctly.

            I stand corrected.

              I don't know if anyone has said this yet, but what I used to do was to unlock the constraint of the gyp at the top in the wall profile, and then just allign it with the top of the gyp of the celing. This seemed to work very well for us.

                Mine join as long as I have them set to the same material and the ceiling is created into wall core.

                  Too much maintenance for not a whole lot of effect. Always been a thorn for me too. The biggest issue of it not cleaning up is less about the sections and more about the double line you can get in elevation or RCP.

                    Class on Ceiling Creation

                    Take a look at this, I did this class years ago but it still works.
