Curtain Wall Settings: Frame Pages (Boundary, Mullion, Transom)

In Curtain Wall System Settings, the Frame pages set the System-level default settings for each Frame class. Click Match All Frame Classes to Current Settings to apply the settings of the current Frame Page to the other two classes of Frames.
Frame Tool Settings contains nearly identical controls. Frame Tool Settings is available in Curtain Wall Edit mode only. Use the Class pop-up to apply System-level Frame settings to the selected Curtain Wall, or to adjust the parameters of Boundary, Mullion or Transom Frames in this Curtain Wall. If you customize any parameters in Frame Tool Settings, the Class pop-up will show “Custom.”
a: Width of Frame Profile
b: Depth of Frame Profile
h: Distance between inner edge of Frame Profile and the Base Surface. (Panels are placed on the Base Surface along the Panel’s centerline.)
d: the length of the panel’s extrusion into the Frame Profile.
w: width of the slot where the Panels connect to the Frame Profile.
If you want these cut line/pen settings to take effect in Floor Plan and Section, make sure you check Enable Frame Type’s Attributes in the Floor Plan and Section panel of Curtain Wall System Settings.
Override Surface: Use this pop-up you wish to override the surface assigned to this frame class.
To override Surfaces, you must first uncheck the Use Frame Building Material's Surface box.
