Curtain Wall Frames

Frames are placed along the Scheme Grid when you create the Curtain Wall.

The Curtain Wall’s pattern of Frames and Panels can be defined in Scheme Settings. (See Set up Grid Pattern in Scheme Settings.)

A Frame must be joined to another Frame at both ends (it cannot “float” independently).

A Frame with adjoining Panels always divides two separate Panels (it cannot bisect a single Panel).

In a multi-segment (Chained) Curtain Wall, a Frame is always placed where two adjacent Curtain Wall segments meet. Such a Frame cannot be deleted, although you can make it invisible.

A Boundary Frame cannot be renamed or removed. The edges of a Curtain Wall always use a Boundary Frame.

 Frame Classes

By default, a Curtain Wall has four classes of Frames: Corner, Boundary, Mullion and Transom.

You can also create other Frame classes: see Curtain Wall Frame Settings.

Boundary Frames are placed along the Curtain Wall Boundary.

Mullion and Transom Frames are placed along either the Columns or Rows of the grid lines

Division Frames are invisible, but they serve to divide panels (they can replace a deleted Frame). See “Division” Frame Class.

In this image, the Frames in the Boundary class are red; the Frames in the Mullion class (coinciding with the grid columns) are blue; and the Frames in the Transom class (coinciding with the grid rows) are green.

Edit Curtain Wall Frames

1.Select the Curtain Wall.

2.Enter Edit mode.

3.Select a Frame.

4.Do any of the following:

Open Frame Selection Settings and change them

Stretch, Drag, Mirror, Rotate or Multiply the Frame

Delete the Frame

Notes: 

Deleting a Frame is only possible if the two panels on either side of the Frame are both in the same plane. On a non-planar Curtain Wall surface, you must first delete the grid line which runs between them. The Frame is deleted along with the grid line.

If you move or delete a grid line, you move or delete the Frame.

See also Multi-selection of Frames and Panels.

Add New Frame to Curtain Wall

1.To add an additional Frame, enter Curtain Wall Edit mode.

2.Activate the Frame Tool.

3.Use the Info Box to define the Frame type and the Frame class whose parameters it should use (e.g. Mullion).

4.Draw a new Frame on the Curtain Wall in Edit mode.

If you draw the Frame on a Grid line, then the Frame will be attached to the grid line. Moving the Scheme Grid will move the Frame.

If you draw a new Frame that crosses an existing grid line, the Frame will be cut into multiple Frames automatically where it crosses the grid line.

Copy Cell Pattern in Curtain Wall

To copy the Frame pattern of any cell in the grid to another cell:

1.Make sure you are in Curtain Wall Edit mode, with the Frames visible.

2.Use Design > Modify Curtain Wall > Copy Cell Pattern.

3.Click in the cell whose Frame pattern you wish to copy.

4.Click in the cell to which to copy the Frame pattern. The Frame pattern is duplicated.

Curtain Wall Frame Intersections

When two or more Frames meet in a Curtain Wall, the Frame with the higher intersection priority will cut the other one.

Note: While a Curtain Wall Frame does have a Building Material, the Building Material’s intersection priority is ignored in this case.

Frame Priorities are defined for each class on the Frames page.

However, you can change the intersection priority of any single selected Frame. In Curtain Wall Edit mode, select the Frame whose intersection priority you want to change. Go to Frame Selection Settings and adjust the slider to the desired level. Changing the Frame’s intersection level - as when changing any other Frame parameter - will result in a Custom Frame.

Curtain Wall Corner Frames

Corner Frames are a separate Frame Class. You cannot rename or remove the Corner Frame class.

When you place a Curtain Wall with multiple segments, the Frame used by the Corner Frame class is placed at the place where each segment joins the next one. (Corner Frames are not placed at curved segments.)

You can technically choose any Curtain Wall Frame as your default Corner Frame, but the Archicad library includes specific Corner Frame objects, such as:

Regular Double Frame with Cap

Regular Double Butt-Glazed Frame

Block Frame with Cap

Block Butt-Glazed Frame

Diagonal Butt-Glazed Frame

Diagonal Frame with Cap

Depending on the selected Corner Frame type, set options and variations in Curtain Frame Settings:

Each Corner Frame uses separate building materials for its components: Frame, gasket and panel, where applicable. You can override surfaces for each as needed.

Corner Frames: Complex Profiles

By default, Archicad includes Profile Corner Frames. You can create custom Profile Frames using the usual methods in Profile Editor. Note that the predefined Profiled Frames include a user origin which ensures the expected behavior for these Frames if the Curtain Wall geometry changes.

See Profile Origin in Profile Editor Window

Create Common Frame for Adjoining Curtain Walls

If two Curtain Wall Base Surfaces join or overlap, use this command to clean up their common corners.

1.Select both Curtain Walls.

2.Use Design > Modify Curtain Wall > Create Common Frames (or the same command from the context menu).

CreateCommonFrameContext.png 

3.Choose the preferred orientation for the common frame (mitered or parallel to an existing frame).

4.As a result, the first joining Frame selected will be transformed into the default Corner Frame, and the other one will be transformed into an Invisible Frame.

Notes on Common Frames

This command does not create a connection between the Curtain Walls (they can be moved or edited separately). If you need a unified element consisting of two adjoining Curtain Walls, it is better to use the Chained geometry method and create these elements in one step to handle them as a single building part.

Note that common frames can only be created at the common nodes of Curtain Wall Base Surfaces, not  the common nodes of their Reference Lines, which are usually offset from Base Surfaces. In the images above, the Reference Lines are blue and the Base Surfaces are green.

See Curtain Wall Components.

This command places the default Corner Frame defined for the Curtain Walls. Set this default Corner Frame component before using the command.

You can change a Corner Frame component at any time using Edit mode.
