    Ventilated facade design in Revit

    Hi guys,

    I am a facade engineer and just started using Revit. After watching a lot of training videos the moment to try it in real came. As I can see, your posts are from 2013, but now I have the same problems as you had than and hope you are the experts . Attached detail is what I would like to achieve. We have the main structure of the building-wall, bracket, vertical T profile, horizontal profile and panel, which is hanged over the horizontal profile. I read a lot of info, but to be honest with you, I am completely lost, because when I try to do something, new problem occurs, than again and again. Below I will explain what approach have chosen, at what stage am I now and what are the problems I face. I will really appreciate your support.

    1. VERTICAL T PROFILES
    APPROACH- I decided to make separate curtain wall with only vertical mullions with custom made T-profiles section.
    PROBLEM: The only problem I face up until now is that I cannot find a way to put 10 mm joint between the vertical mullions.
    2. HORIZONTAL PROFILES+PANELS
    APPROACH- I made second curtain wall (the first one is only for Vertical mullions T-profiles), where I put only horizontal mullion profiles and panels. Since I have 6 types of panels with different width and height, I made 6 curtain-wall-panels families for each type (I put the hangers into the families and made the panels with 5 mm shorter at top,bottom,left,right so I can have 10 mm joint between the separate panels). And here come my problems:

    PROBLEM 1 -when I try to change the type of only one panel in the curtain wall from the menu-Edit Type, all of the panels change. All my attempts to implement the created curtain-wall-panels families into my curtain wall, leads to total mess in the geometry. Now I am wondering if it is possible to have different curtain panels (custom made families) in one curtain wall?
    PROBLEM 2 - when I try to add more horizontal curtain grids, so I can assign them with the custom made section of the horizontal mullion, that leads to changes in the geometry of the panels, I guess because Revit thinks that these horizontal grids are joints and split the original panels. Please let me know how to position the horizontal mullions, which have to work as horizontal profiles and do not mess the geometry.
    PROBLEM 3 - As you can see the horizontal profile is tubular with hook. Revit did not allow me to make the opening of the profile and now it is done solid. How to fix this? Also do you know if it is possible to have 10 mm joints between the horizontal mullions?

    Please let me know in general if my approach is correct and if possible let me know the solution of my problems. Also I was thinking if it would be better to make 3 layers (not two as now) of curtain walls- 1 layer: only vertical mullions; 2 layer: only horizontal mullions; 3 layer-only panels and put them on top of each other? Also then for the scheduling and specification would it be a problem if done that way?

    Kind Regards,
    Dimitar

    If going this route, I'd do 3 CW's. 1 for the vertical T, 1 for the horizontal, then 1 for just the panels.

    You can assign a panel type to a Curtain Wall as a default, then you can switch them after. 3D or an elevation is easiest, hover your cursor over the panel then hit "Tab". You might have to make it editable or unlock it. Then you can change the panel type for just that one panel.

    10mm joint on the horizontal. The "mullion" follows the grid, so you would have to add 2 vertical gridlines, one on either side of the vertical centerline.

    Thank you for your comment. I did it with 3 layers and seems that it is working good.

    Do you know if it is possible to make opening in horizontal profile, because it is solid now? Check the attachment please.

    Thats good to hear. I didnt want to be a naysayer when this initiative was going on, but my original thought was (in the US, at least) a lot of that would be covered in Wall Sections and Details, and modeling discreet elements for it all would be above and beyond the architectural scope (but still cool as heck!). The mullion tools really are the pathetic part of the RCW tools. Im looking at an initiative for an interior demountable partition client, and we are going to make an app (potentially) that stick builds the entire thing, because RCW blows at the details.

    2 options. Insert a detail component on the view or insert the detail component into the profile. You can't model it as a hollowed out section with CW mullions.

    I really should have separated this to a new thread...since you responded to a 6 year old post...
