Description

The Arch Window tool creates a base object for all kinds of "embeddable" objects, such as windows and doors. It is designed to be either independent, or "hosted" inside another component such as an Arch Wall, Arch Structure, or Arch Roof. It has its own geometry, that can be made of several solid components (commonly a frame and inner panels), and also defines a volume to be subtracted from the host objects, in order to create an opening.

Window objects can be based on closed 2D objects, such as Draft Rectangles or Sketches, that are used to define their inner components. The base 2D object must therefore contain several closed wires, that can be combined to form filled panels (one wire) or frames (several wires).

The Window tool features several presets. These allow the user to create common types of windows and doors with certain editable parameters, without the need to create the base 2D objects and components manually.

All information applicable to an Arch Window also applies to an Arch Door, as it is the same underlying object.

Usage

There are different ways to create windows, depending on the desired level of detail and functionality.

Creating a window from a preset

This is the most straightforward way of creation, where existing presets cover the most general types of windows.

  1. There are several ways to invoke the tool:
    • Press the Window button.
    • Select the 3D/BIM → Window option from the menu.
    • Use the keyboard shortcut: W then I.
  2. Select one of the presets in the list.
  3. Fill out the desired parameters.
  4. In the 3D View, move the window to the location where you wish to place it. If you move the pointer over an Arch Wall, the outline of the window should align itself with the face of that object.
  5. Click on the 3D View with the mouse, or press the Enter key three times to confirm the X-, Y-, Z-coordinates of the placement.

Learn more about presets.

Creating a window from custom components

When the desired window format is not covered by any of the existing presets, custom windows can be created and optionally included as user presets in addition to the built-in presets.

  1. Optionally, select a face on the Arch object where you want the window to be included, and then set the working plane to it.
  2. Create a new sketch with the New Sketch command on the current working plane.
  3. For proper placement, the bottom left hand corner of the window should be at the sketch origin.
  4. Draw one or more closed wires (loops). Pay close attention to the creation order of these loops, the numbering of the "wires" in the task panel ("Window elements") depends on this.
  5. Close the sketch.
  6. Select the sketch and press the Window button, or any of the alternative ways to invoke the tool.
  7. To adjust the window components and various properties, enter the window task panel by double-clicking on the created object in the Tree View.
  8. Note that since components following a hinged component will also hinge, all fixed components, such as outer frames and fixed glass panels, must be defined before any hinged components. And a glass panel in a hinged frame must be defined after that frame, and before any other hinged components.

Learn more about custom components.

Creating a window from custom types

  1. Create a window frame object, a glass panel, and any other window component you need, using Part Workbench or PartDesign tools.
    • For example, create a base rectangular sketch for your window, then a profile sketch for the frame, and create a Part Sweep to sweep the profile around the base sketch. Create a Part Offset2D from the base sketch, then a Part Extrude to create the glass panel
    • Optionally, create a volume to be subtracted from the wall, for example by extruding the base sketch.
    • Make sure all these pieces have a unique, meaningful name (for example, "Frame" or "Glass panel")
  2. Create an App Part, and place all your subcomponents in it
    • If you have created one, make sure the subtraction volume's visibility is turned off
  3. If you want to make your window parametric, you can add 3 properties to your App Part, by right-clicking its Property View and selecting "Add Property". Add the following properties (all of them are optional, the property group doesn't matter):
    • Height as a PropertyLength and link it, for example, to a vertical constraint of your base sketch.
    • Width as a PropertyLength and link it, for example, to a horizontal constraint of your base sketch.
    • Subvolume as a PropertyLink and link it to the volume to be subtracted that we created above.
    • Tag as a PropertyString.
  4. To create window objects from the newly-created type. select the App Part and press the Window button, or any of the alternative ways to invoke the tool.

The ДаніHeight, ДаніWidth, ДаніSubvolume and ДаніTag properties of the window will be linked to the corresponding property of the App Part, if existing.

Openings

See also: Tutorial for open windows

Doors and windows can appear partially or fully opened in the 3D model, or can display opening symbols both in plan and/or elevation. Consequently, these will also appear in extracted 2D views generated by Draft Shape2DView or the TechDraw Workbench. To obtain this, at least one of the window components must have a hinge and an opening mode defined (see Custom components). Then, using the ДаніOpening, ДаніSymbol Plan or ДаніSymbol Elevation properties, you can configure the appearance of the window:

Presets

The following presets are available:

Additional user presets

In addition to the default presets, the window tool can also use custom presets. A custom preset is a FreeCAD file containing a single window based on a parametric sketch that has two named constrains: Width and Height. Custom presets can be placed in the following locations:

$ROOT_DIR/Arch/Doors/Custom/
$ROOT_DIR/Arch/Windows/Custom/

If you install the Parts Library from the Addon Manager, the window tool will also search this library for additional presets at this pair of locations:

$ROOT_DIR/Mod/parts_library/Architectural Parts/Doors/Custom/
$ROOT_DIR/Mod/parts_library/Architectural Parts/Windows/Custom/

Custom presets will be available in the window tool's presets dropdown menu. Presets in library locations will also be available in the Parts Library dialog.

Custom components

You can access, create, modify and delete components of a window in edit mode (double-click the window in the Tree View).

Windows can include 4 types of components: frames, solid panels, glass panels and louvres. Panels and louvres are made from one closed wire, which gets extruded, while frames are made from 2 or more closed wire, where each one is extruded, then the smaller ones are subtracted from the biggest one.

The components have the following properties:

Custom types

Windows can also take advantage of other tools, specifically PartDesign workflows, to define a type. A type is an object that defines the shape of the window. This is specially well suited to work with Std Parts:

Note that windows created in this manner do not support the Openings features.

Materials

To build a material for type-based windows:

You can use any other kind of workflow than the one described above, the important points to remember are:

Properties

An Arch Window object shares the common properties and behaviors of all Arch Components.

Scripting

See also: Arch API and FreeCAD Scripting Basics.

The Window tool can be used in macros and from the Python console by using the following function: 

Window = makeWindow(baseobj=None, width=None, height=None, parts=None, name="Window")

Example: 

import FreeCAD as App
import Draft
import Arch

rect = Draft.makeRectangle(length=900, height=3000)
# Optional: rotate it to be on the XZ plane, so that the window is upright
rect.Placement.Rotation = App.Rotation(App.Vector(1, 0, 0), 90)
App.ActiveDocument.recompute()
Window = Arch.makeWindow(rect)
App.ActiveDocument.recompute()

You can also create a Window from a preset. 

Window = makeWindowPreset(windowtype, width, height, h1, h2, h3, w1, w2, o1, o2, placement=None)

Example: 

import FreeCAD as App
import Arch

base = App.Vector(2000, 0, 0)
axis = App.Vector(1, 0, 0)
place= App.Placement(base, App.Rotation(axis, 90))

door = Arch.makeWindowPreset("Simple door",
                             width=900, height=2000,
                             h1=100, h2=100, h3=100, w1=200, w2=100, o1=0, o2=100,
                             placement=place)
