Описание

Этот инструмент создает объект Wall с нуля или поверх любого другого объекта shape или mesh. Стена может быть построена без какого-либо базового объекта, и в этом случае она ведет себя как кубический том, используя свойства длины, ширины и высоты. При построении поверх существующей формы стена может основываться на:

  • A linear 2D object, such as lines, wires, arcs or sketches, in which case you can change thickness, alignment (right, left or centered) and height. The length property has no effect.
  • A flat face, in which case you can only change the height. Length and width properties have no effect. If the base face is vertical, however, the wall will use the width property instead of height, allowing you to build walls from space-like objects or mass studies.
  • A solid, in which case length, width and height properties have no effect. The wall simply uses the underlying solid as its shape.
  • A mesh, in which case the underlying mesh must be a closed, manifold solid.

Walls built from a line, a wire, a face, a solid, and a sketch

Walls can also have additions or subtractions. Additions are other objects whose shapes are joined in this Wall's shape, while subtractions are subtracted. Additions and subtractions can be added with the Arch Add and Arch Remove tools. Additions and subtractions have no influence over wall parameters such as height and width, which can still be changed. Walls can also have their height automatic, if they are included into a higher-level object such as floors. The height must be kept at 0, then the wall will adopt the height specified in the parent object.

When several walls should intersect, you need to place them into a floor to have their geometry intersected.

Применение

Рисование стены с нуля

  1. Нажмите кнопку Arch Wall.svg Arch Wall, или нажмите W, затем A.
  2. Щелкните первую точку на трехмерном изображении или введите первую координату.
  3. Нажмите вторую точку на трехмерном представлении или введите вторую координату.

Drawing a wall on top of a selected object

  1. Select one or more base geometry objects (Draft object, sketch, etc)
  2. Press the Arch Wall.svg Arch Wall button, or press the W then A keys
  3. Adjust needed properties such as height or width.

Опции

  • Walls share the common properties and behaviours of all Arch Components
  • The height, width and alignment of a wall can be set during drawing, via the task panel
  • When snapping a wall to an existing wall, both walls will be joined into one. The way the two walls are joined depends on their properties: If they have the same width, height and alignment, and if the option "join base sketches" is enabled in the Arch preferences, the resulting wall will be one object based on a sketch made of several segments. Otherwise, the latter wall will be added to the first one as addition.
  • Press X, Y or Z after the first point to constrain the second point on the given axis.
  • To enter coordinates manually, simply enter the numbers, then press Enter between each X, Y and Z component.
  • Press R or click the checkbox to check/uncheck the Relative button. If relative mode is on, the coordinates of the second point are relative to the first one. If not, they are absolute, taken from the (0,0,0) origin point.
  • Press Shift while drawing to constrain your second point horizontally or vertically in relation to the first one.
  • Press Esc or the Cancel button to abort the current command.
  • Double-clicking on the wall in the tree view after it is created allows you to enter edit mode and access and modify its additions and subtractions
  • Multi-layer walls can be easily created by building several walls from the same baseline. By setting their Align property to either left or right, and specifying an Offset value, you can effectively construct several wall layers. Placing a window in such a wall layer will propagate the opening to the other wall layers based on the same baseline.
  • Walls can also make use of Multi-Materials. When using a multi-material, the wall will become multi-layer, using the thicknesses specified by the multi-material. Any layer with a thickness of zero will have its thickness defined automatically by the remaining space defined by the Wall's Width value, after subtracting the other layers.
  • Walls can be made to display blocks, instead of one single solid, by turning their ДанныеMake Blocks property on. The size and offset of blocks can be configured with different properties, and the amount of blocks is automatically calculated. introduced in version 0.18

Привязки

Привязка к стенам Arch работает немного иначе, чем с другими объектами Arch и Draft. Если стена имеет базовый объект, привязка будет привязана к базовому объекту, а не к геометрии стены, что позволит легко выровнять стены по их базовой линии. Однако, если вы специально хотите привязаться к геометрии стены, нажатие Ctrl переключит привязку на объект стены.

Свойства

Wall objects inherit the properties of Part objects, and also have the following extra properties:

  • ДанныеAlign: The alignment of the wall on its baseline: Left, Right or Center
  • ДанныеBase: The base object this wall is built on
  • ДанныеFace: The index of the face from the base object to use. If the value is not set or 0, the whole object is used
  • ДанныеForce Wire: If True, and the wall is based on a face, only the border wire of the face is used, resulting in a wall bordering the face
  • ДанныеLength: The length of the wall (not used when the wall is based on an object)
  • ДанныеWidth: The width of the wall (not used when the wall is based on a face)
  • ДанныеHeight: The height of the wall (not used when the wall is based on a solid). If no height is given, and the wall is inside a floor object with its height defined, the wall will automatically take the value of the floor height.
  • ДанныеNormal: An extrusion direction for the wall. If set to (0,0,0), the extrusion direction is automatic.
  • ДанныеOffset: This specifies the distance between the wall and its baseline. Works only if the Align property is set to Right or Left.

представлено в версии 0.18:

  • ДанныеMake Blocks: Enable this to make the wall generate blocks
  • ДанныеBlock Length: The length of each block
  • ДанныеBlock Height: The height of each block
  • ДанныеOffset First: The horizontal offset of the first line of blocks
  • ДанныеOffset Second: The horizontal offset of the second line of blocks
  • ДанныеJoint: The size of the joints between each block
  • ДанныеCount Entire: The number of entire blocks (read-only)
  • ДанныеCount Broken: The number of broken blocks (read-only)

Программирование

См. так же: Arch API и Основы написания скриптов FreeCAD.

Инструмент «Стена» может использоваться в макросах и на консоли Python с помощью следующей функции:

Wall = makeWall(baseobj=None, length=None, width=None, height=None, align="Center", face=None, name="Wall")
  • Creates a Wall object from the given baseobj, which can be a Draft object, a Sketch, a face, or a solid.
    • If no baseobj is given, you can provide the numerical values for the length, width (thickness), and height.
    • If given, face can be used to give the index of a face from the underlying object, to build this wall on, instead of using the whole object.
  • align can be "Center", "Left" or "Right".
  • It returns None if the operation fails.

Пример:

import FreeCAD, Draft, Arch

p1 = FreeCAD.Vector(0, 0, 0)
p2 = FreeCAD.Vector(2000, 0, 0)
baseline = Draft.makeLine(p1, p2)
Wall1 = Arch.makeWall(baseline, length=None, width=150, height=2000)
FreeCAD.ActiveDocument.recompute()

Wall2 = Arch.makeWall(None, length=2000, width=200, height=1000)
Draft.move(Wall2, FreeCAD.Vector(0, -1000, 0))
FreeCAD.ActiveDocument.recompute()
