    Centering ceiling grid

    Hey guys-

    It seems like this should be easy -
    We've created ceiling planes in our model, and subsequently shifted some of the room configurations. Is there an easier way to center the ACT grid on the new walls?... currently I'm making dimensions and hitting equal, then deleting, etc, etc. This would be fine except I have about a million rooms. Assuming there's a setting in align that would allow me to pick the CL of a wall... similar to picking the CL of fixtures... that I just dont see.

    Thanks in advance.

    A million rooms?? Wow... But no, don't believe that there's a easier way. Unless the ceiling tiles needs to be moved by a known distance? Then you can simply select the grids and move them...

      Yup. that's almost literal. A million.

      Thanks for reaffirming the process.

        By the sound of it you should have a work in progress view setup with those dimensions permenantly shown on it so you dont have to keep on drawing the dimension....

          Center the Tile instead of the grid in all ceilings of a type..

          I found a way to have all the ceilings automatically center the “tile” and not the “grid”. JFYI.

          Create a new material (or edit the current ACT material)
          Then us this custom pattern file (attached) – when importing the model hatch, scale by a factor of 24 (for 24”x24” tiles). For 24x48 inch ceiling tiles, use the “centered 24x48” file attached. Scale by 48 when importing.

          In the Edit Type dialogue for the ceiling, apply the new material to the ceiling surface.

          Also if you have already created your ceilings, this will retroactively change all the ceiling patterns if you change the ceiling type to have the new pattern.

            Good idea but this still doesnt solve a fundamental problem with ceiling grids in revit....
            If you look in 3D the tile layout is different on the top and bottom of the ceiling <Mr Palm, meet Mr Face.>
            I was hoping your solution would solve this but it is just the same.



            We once did a whole MEP project with all the fixtures neatly centred in the tiles (As seen in MEP views from above and 3D views showing everything above the ceiling), only to get an irate mail from the architect complaining that us engineering types have no concept of aesthetics...

              Auto centering is a great idea, but it is not always the best look. One must balance the centered look with the desire to reduce the number of cuts to the ceiling material in the field.

                So ideally you would always choose a corner of the room (Could default to upper left or something to make it automatic) and then start adding whole tiles from there until you reach the cut tiles on the other side?

                Unfortunately ceilings are not accessible via the API but I have seen models with curtain walls or sloped glazing used as tiles and theres some discussion about auto generating the framework here; https://forum.dynamobim.com/t/model-...dynamo/4530/30

                If your model ONLY contains rectangular rooms (Or shapes that can be made with a few rectangles) it would be fairly easy to make a family with variable width/length that contains an array of 'tile' families. This could be placed in the model using coordinates from the Room corners, or manually with Align.

                  It is a aesthetic/cost/environment balance. Every tile that is cut takes additional labor and generates waste.
                  Sometimes I balance the room with cut tiles on both sides. Other times the cut tiles are too thin and the best design is to have one side with cut tiles. Generally any cut tile that is less than 6" means shifting things to eliminate them.
