Описание
Этот инструмент помещает в текущий документ "что-то" секущей плоскости, которое определяет сечение или план. "Что-то" получает своё положение в соответствии с текущей рабочей плоскостью, и может быть перемещён и переориентирован через её перемещение и вращение, пока не получится требуемый двумерный вид. Секущая плоскость учитывает только определённый набор объектов. Выделенные в момент создания секущей плоскости добавляются в этот набор автоматически. Другие объекты могут быть позднее добавлены или удалены из объекта SectionPlane инструментами Arch Add component или Arch Remove component, или двойным кликом секущей плоскости в древе проекта.
The Section Plane object will only consider a certain set of objects. Objects that are selected when you create a Section Plane will be added to that set automatically. Other objects can later be added or removed from a SectionPlane object with the Arch Add and Arch Remove tools, or by double-clicking the Section Plane in the Tree View.
Сама по себе плоскость сечения не создаст никакого вида набора своих объектов. Для этого вы должны либо создать Drawing DraftView, чтобы создать вид на странице чертежа, Draft Shape2DView для создания вида в самом 3D-документе, или TechDraw ArchView для создания представления на странице TechDraw.
Применение
- Если нужно, установить Draft Working Plane для отражения плоскости, на которой вы хотите разместить плоскость сечения.
- Выделить объекты, которые должны быть включены в сечение
- Нажмите кнопку
SectionPlane или нажмите S, затем P
- Move/rotate Section Plane в правильное положение, если нужно.
- Выберите плоскость сечения, если она еще не выбрана.
- Используйте
Drawing DraftView,Draft Shape2DView или TechDraw ArchView для создания вида.
Typical drawing workflow
The typical workflow to create a 2D drawing involves the following steps, also reflected in the buttons' order in the toolbar:
- Create a
Section Plane, and place it correctly in the model. As described before.
- Create a drawing view with the
2D Drawing tool. A drawing view is simply a BuildingPart that has been modified to be recognized as a 2D drawing (and stripped of some attributes like level, height, etc). Using a BuildingPart has a few advantages: It defines a working plane, you can move it and it will also move its contents, and it has a "title" that shows in the viewport. But fundamentally, the drawing view is just a container for the components of your 2D drawing. If the Section Plane is selected before initiating the 2D Drawing command, both the Section View and Section Cut objects mentioned in the next step are created automatically.
- Create a
Section View and if needed, a
Section Cut from your Section Plane. Both tools produce a Shape2DView, but the first one in "solid" mode, which shows projected lines from what is viewed by the Section Plane, and the second one in "cut lines" mode, so it shows only the cut lines (the intersection between the Section Plane and the model). In plans and sections, you will want both, and give the section Cut a bit thicker line width, in elevations you will typically only need the section View, as there is nothing to cut. Then, of course, you place both these objects, in the drawing view.
- Create all needed annotations like dimensions, texts, 2D linework, etc… and add them to the drawing view.
- Create a TechDraw page using the
Page tool of the BIM Workbench. It will pop up a dialog to let you select an SVG file to use as a template (and remembers the last used template).
- Once you have your drawing view and your page, select both and press the
View button. This will create a TechDraw view on the page, showing the contents of your drawing view.
Опции
- The Section Plane object will only consider a certain set of objects, not all the objects of the document. Objects can be added or removed from a SectionPlane object by using the Arch Add and Arch Remove tools, or by double-clicking the Section Plane in the Tree View, selecting objects either in the list of in the 3D View, and pressing the
Add Selected or
Remove buttons.
- С выбранным объектом сечения используйте инструмент Draft Shape2DView для создания объекта, представляющего вид сечения в документе.
- Создайте дополнительные Drawing DraftViews, если Вы работаете с
верстаком Drawing, или TechDraw ArchView, если Вы используете верстак TechDraw.
- The Section Plane can also be used to show the entire 3D View cut by an infinite plane when ВидCutView is set to
true. This is only visual, and won't affect the geometry of the objects being cut.
Свойства
Data
SectionPlane
- ДанныеOnly Solids: Если это
true, объекты не твердых тел не будут учитываться в наборе. - ВидDisplay Length: Длина "чего-то" плоскости сечения на трехмерном виде. Не влияет на итоговый вид
- ВидDisplay Height: Высота "чего-то" плоскости сечения в трехмерном виде. Не влияет на итоговый вид
- ВидArrow Size: Размер стрелок в "чём-то" секущей плоскости в трёхмерном виде. Не влияет на итоговый вид
- ВидCut View: Если это
true, весь трёхмерный вид будет рассечён по месту этой секущей плоскости. - ВидClip view: Если это
true, он будет обрезать вид до отображаемой высоты и длины плоскости сечения. Это эффективно превращает плоскость сечения в ортогональную камеру, ограничивая поле зрения. introduced in 0.19
The Arch SectionPlane with the ДанныеClip property set to true will behave like a camera, limiting the field of view.
View
SectionPlane
- ВидArrowSize: The size of the arrow symbol at the corners of the Section Plane in the 3D View. This value also controls the length of the lines indicating the view direction. Doesn't affect the resulting view.
- ВидCutDistance: This property is deprecated and has no effect. It was originally intended to create a thick visual slice in the 3D View.
- ВидCutMargin: A small offset distance to apply between the Section Plane and the actual real-time cut plane when ВидCutView is active. This helps prevent graphical artifacts (Z-fighting) on co-planar faces.
- ВидCutView: If
true, enables a real-time clipping effect in the 3D View, visually cutting through the model at the plane's location. - ВидDisplayHeight: The height of the Section Plane's visual representation in the 3D View. This dimension is also used to define the boundary of the 2D view when the ДанныеClip data property is set to
true. - ВидDisplayLength: The width of the Section Plane's visual representation in the 3D View. This dimension is also used to define the boundary of the 2D view when the ДанныеClip data property is set to
true. - ВидFontSize: The size of the label text that is displayed in the 3D View.
- ВидFontName: The font used for the label text.
- ВидShowLabel: If
true, the object's ДанныеLabel will be displayed next to the Section Plane in the 3D View. - ВидTransparency: Controls the transparency of the Section Plane's face in the 3D View, from 0 (fully opaque) to 100 (fully invisible).
Tweaks
- Manually adding a property named RotateSolidRender of type App::PropertyAngle to the Section Plane's View properties (right-click the properties view, select Show hidden from the context menu, right-click again and select Add property) allows to rotate the render when using Solid mode. This is useful when a rendered view has for example both Arch and Draft elements, and the rendering of the Arch elements is rotated in relation to the Draft elements.
Alternative workflows
- The commands Draft Shape2DView and/or TechDraw ArchView can also be used to create a view from a Section Plane. However, it is recommended to use the dedicated BIM workbench tools described here instead.

Инструмент SectionPlane может использоваться в макросах и в консоли Python с использованием следующих функций:
Section = makeSectionPlane(objectslist=None, name="Section")
- Создаёт объект
Sectionизobjectslist, который есть список объектов.

p2 = FreeCAD.Vector(2000, 0, 0)
baseline = Draft.makeLine(p1, p2)
baseline2 = Draft.makeLine(p1, -1*p2)
Wall1 = Arch.makeWall(baseline, length=None, width=150, height=2000)
