    Looks to me like you're having constraint issues, meaning your nested families won't stretch properly. Do some research on reference planes and how their constraint settings change their behaviour - strong, weak, not a reference, defines origin etc.

    It's not always neccessary (or possible) but start by setting all of your length type parameters in the child families to instance based, align and lock them to the correct references in the parent family and link the parameters through as well.

    Ok, I'll look into the constraints I have set up. Are Aaron's doors not stretching to fill the hole on purpose? Or have I downloaded the incorrect files?
    Thanks!

    Without getting my mitts on the family... my money, on why things are "breaking" when you switch types, is because of inconsistent parameter association.


    Example:

    1. Parent CWP instance parameter <Width> = tied to Child Door-Panel instance parameter <Width>
    2. Child Door-Panel instance assigned to CWP type/instance-based family swap parameter <Panel Type>
    3. Swap the Child Door-Panel using the CWP parameter from "Door-Panel-Family-1" to "Door-Panel-Family-2"
    4. Family breaks... because, "Door-Panel-Family-2" has a parameter called <width> and not <Width> - so the association/tie fails.

    That’s as intended so that you don’t have unexpected dimensions in schedules. Instead of moving the mullions to obtain a specific size, you set the size and move the mullions to fit.

    Hey there. As mentioned, this is intentional... And they ARE scaling with the Curtain Wall Grids. Just the PANELS are not.

    With ANYONE's curtain wall doors, you have a choice, when CW Grids move: Jacked up fitment within the model, or Jacked up Door schedule. All of the doors (including OOTB) that auto-stretch when the grids are edited, LOOK correct in the model, but the door schedule ends up showing 6-0 111/256". I cant stand that. So the TRF doors (and the newer PRLX doors) all leave the PANELS the size input in the parameters, and the FRAME (if present, and there isnt always one) stretches with the CW Grids. There is also a reporting parameter that is always telling you the difference, so you automatically know how much to move the grids OR change the sizes.

    But this has little to do with your issue, which seems to be a constraint issue. By chance, is your Panels origin the centerline, instead of the Hinge point?

    Correct, not what you'd expect, but this is a better method as Aaron described.
    If you look at his, you'll see some "compare" parameters, this is the secret sauce to make this method work. You can either set your mullions then adjust the door size to suit them OR you can set the door size, then adjust the mullions to close the gap.

    I just inserted about 2 dozen exterior doors in curtain wall and giggled the whole time how easy it was.

    *I just reread Aaron's post and reiterated what he said *

    Thanks for chiming in!

    The one thing I still don't understand is this:

    Why is there a problem with the schedules in the case of auto-fitting panels? If I understand things correctly, if the frame is the proper width, and the panel is the proper distance from the frame, shouldnt the calculations work correctly?
    Let's say we a have a 1 meter space between curtain grids. Now let's say our frame is 10cm wide, so our panel is offset 10 cm inside. Isn't everything the correct, real-world size?

    I'm sure there's a good reason for doing things the way you have, I'm just trying to understand the logic behind it.

    Thanks for all your help!

    (Also, Aaron, my panel origin was in the center, not the hinge... obvious mistake in hindsight, thanks!!)

    What you are missing is that things don't always get designed to be whole numbers. The grids aren't always 1m apart. Sometimes they are .980m, or 1.15m, depending on the layout of the rest of the building.

    *tongue-in-cheek* gee thanks for convincing me to do even more work. I was going to be making some CW doors soon so now I have more digging to do. Thanks in advance for saving me a lot of frustration yet again

    Well gridlines are typically to the centerline of the mullion (unless your mullion profile is offset, but then your going to start making life difficult for you). So in your case, the panels would have to be mullion width/2 for an offset. Not sure why you need the offset, as the panel should fill to the edge of the mullion.

    Pure ease in being flexible for both situations - moving mullion gridlines to suit a particular door width or fitting a door width to a fixed mullion width. Auto fill can work, just needs a bit more work when you need a specific door width.
