    Curtain Wall Corner


    I'm trying to create custom corner curtain wall panels using the Curtain Wall Family.

    I have been having some issues with the panel generation. I am able to set up the panel in the family model space and it seems to work in exactly the way i want it to and it also seems to be adaptive i.e if i move the edge reference planes the panel adjusts in the correct manner. However the panel dose not react in the same way in the model space. There are a number of strange things happening that don't make any logical sense outlines below.

    1. The orientation of the panel is mirrored when loaded into the model space, the corner condition is clearly on the right hand side when looking at the panel face from the exterior but when loaded into the model it appears on the left hand side of the panel. (I have tried this with both left and right corner panels.

    2. Even when i constrain the panel to a dimension of 5ft which is the fixed spacing between the grid lines in the model, when loaded into the model it is far smaller then that?

    I am Overwriting the existing version and its parameters every time i load the family into the model, both the dimensions and tolerances between the model and the family are matching.

    Iv'e been through a number of curtain wall tutorials but cant find what is going wrong here, obviously missing something key as this is not making any logical sense.

    Any suggestions would be great.

    just looking at the constraints in the image, you have 5ft constrained but then everything is drawn to reference planes fraction of an inch to the interior. Is this distance fixed? if so lock these also, and make sure your element is aligned to ref planes and locked to the planes also. As for why it comes in with the odd orientation, hard to say but just add some controls that allow you to flip the direction this will overcome the issue and adds some flexibility to your family actually.

    it seems to me the length issue is because you havent constrained the fractional dimensions on the edges but this may not be the case, so its a starting point


      a 'trick' you can use is to replace the panels with walls (just the one at the corner). The walls will join like they do when you place them by temselves. BUT if you are scheduling the panels for example, this might not be the best way to do this.

        Karalon, thanks for the reply. Yes everything is locked to the reference places which have locked dimensions as well. But will look into adding a flipping control!


          I have a feeling your angled reference plane is the issue here. Reference planes can not/should not be constrained on an angle. Can you draw the dimension constraints in the sketch of your panel? Does the angle need to be parametric?

            Yes i think the angled reference plane could be causing some issues here, its constrained by a linear dimension to the intersection point of the edge. Highlighted in the imaged attached.

            The thing that is perplexing is the difference in dimensions from the family and the model, if the panel is constrained at 5ft and i create a void form in the correct place i shouldn't need to constrain it because it should just be in the correct place. However when i try this the void is no where near the edge of the panel.

              The way I understand the Curtain Panel template to work is that the built-in reference planes are automatically aligned to the mullion grid edges, wherever they are. This is what allows the panels to adjust to different grid spacing. If you really need to lock a panel to a hard dimension, try creating and using separate reference planes instead of the ones built into the template. There's some trickiness to getting the panel to land where you are expecting it to (based on where the panel thinks it's center is, and how far it is offset from the location line).
