    Curtain Wall Border Mullions

    While creating an exterior wall it is my understanding that when drawing in a clockwise path Revit will put the exterior finished face of a wall towards the outside of the building.

    If using this same concept to get the exterior face of a curtain wall, what Border Types are which as far as mullion placement goes?

    Vertical Mullions:

    Interior Type: This is self expainatory.
    Border 1 Type: Left side or right side as viewed from the exterior face (assuming wall in drawn in a clockwise manner)?
    Border 2 Type: Left side or right side as viewed from the exterior face (assuming wall in drawn in a clockwise manner)?

    Horizontal Mullions:

    Interior Type: This is self expainatory.
    Border 1 Type: Top or Bottom?
    Border 2 Type: Top or Bottom?

    Thank you very much!

    dragging the curtain wall left to right when you place them will maintain an exterior down orientation. Doesn't make a difference for horizontal mullions but it does for vertical border types 1 and 2 (jambs). I differentiate between left and right jambs so I need the left on the left and the right on the right. In the TP dialog under vertical mullions Border 1 Type is the right jamb and Border 2 Type is the left jamb, if you drag from left to right on placement. In the Horiz mullions are Border 1 type is the sill and Border 2 type is the head. HTH

      Thank you. My concern with that is the location of the exterior face of the wall in order to determine left/right

      When I draw a wall from left to right it puts the exterior finish in an "up" orientation (see attached) and when I draw from right to left it puts the exterior finish in a "down" orientation (see attached) The attached jpg is used with a basic wall because it's easier to see the exterior vs interior side with a basic wall than it is with just a curtain wall. Am i missing something?

      I understand the horizontals now, however if I am looking at the exterior face of the curtain wall then the left vertical is Border Type 2 and the right vertical is Border Type 1?

      Sorry for the confusion.

        to me, as a curtain wall detailer, the exterior is always the side that the glass is located towards. While this is not always true in real life it's a fact in 75% of cases. Of the 25% left over 24% is glass in the center but the exterior is still important so my jambs get placed correctly. And you're right I was bassackwards. To have the exterior of the curtain wall down you drag right to left.

          Not sure why the devs can't tell us which is the beginning (start) and which is the end once a wall is placed - especially curtain wall.

          Vertically
          Border 1 = Start Point
          Border 2 = End Point

          Horizontally
          Border 1 = Base
          Border 2 = Top

          Which side is Exterior when you first place a wall?
          Start Left, End Right = Exterior on the top.
          Start Right, End Left = Exterior on the bottom.
          Start Top, End Bottom = Exterior on the right.
          Start Bottom, End Top = Exterior on the left.

          Once a wall gets flipped it becomes trial and error to figure out which is start and end. Devs need to give us a fighting chance to figure which is which.
