Beskrivning

Detta verktyg placerar en sektionplansvisare i nuvarande dokument, vilken definierar ett tvärsnitt eller vy-plan. visaren kan omplaceras och omorienteras genom att flytta och rotera den, tills den visar den 2D vy som du vill erhålla. Om verktyget används utan att några objekt är markerade, så kommer alla objekt från scenen att inkluderas i 2D vyn. Om några objekt är markerade, så kommer 2D vyn endast att visa dessa objekt.

Objekt kan senare adderas eller tas bort från ett SectionPlane objekt med Arch Add och Arch Remove verktygen.

Vid skapandet, så skapar SectionPlane objekt för närvarande ett Ritningssida objekt vilken innehåller den projicerade 2D vyn av de objekt som behandlas av Section Plane.

Till vänster i bilden ovan placeras ett Section Plane objekt i scenen, och till höger dess SVG 2D representation. Ytsortering är för närvarande inte helt implementerad.

Bruk

Välj objekt
Klicka på SectionPlane knappen
Flytta/rotera Section Plane till korrekt position
Klicka på Beräkna om knappen för att uppdatera vyn

Options

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 scene, and pressing the add or remove buttons.

With a section plane object selected, use the Draft Shape2DView tool to create a shape object representing the section view in the document

Create Drawing DraftViews if you are working with the ~~Drawing Workbench~~, or TechDraw ArchView if you are using the TechDraw Workbench.

The Section Plane can also be used to show the entire 3D view cut by an infinite plane. This is only visual, and won't affect the geometry of the objects being cut.

Properties

DataOnly Solids: If this is True, non-solid objects in the set will be disregarded
VyDisplay Length: The length of the section plane gizmo in the 3D view. Doesn't affect the resulting view
VyDisplay Height: The height of the section plane gizmo in the 3D view. Doesn't affect the resulting view
VyArrow Size: The size of the arrows of the section plane gizmo in the 3D view. Doesn't affect the resulting view
VyCut View: If this is true, the whole 3D view will be cut at the location of this section plane.
VyClip view: if this is true, it will clip the view to the display height and length of the section plane. This effectively turns the section plane into an orthographic camera, limiting the field of view. introduced in version 0.19

The Arch SectionPlane with the clip view option will behave like a camera, limiting the field of view.

Tweaks

Adding manually a property named RotateSolidRender of type App::PropertyAngle to the section plane's View properties (right-click the properties view -> show all, right-click again -> 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. introduced in version 0.19

Scripting

See also: Arch API and FreeCAD Scripting Basics.

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

Section = makeSectionPlane(objectslist=None, name="Section")

Creates a Section object from objectslist, which is a list of objects.

Example:

import FreeCAD, Draft, Arch

p1 = FreeCAD.Vector(0, 0, 0)
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)
Wall2 = Arch.makeWall(baseline2, length=None, width=150, height=1800)
Structure = Arch.makeStructure(length=1000, width=1000, height=200)
FreeCAD.ActiveDocument.recompute()

BuildingPart = Arch.makeBuildingPart([Wall1, Wall2])

Floor = Arch.makeFloor([BuildingPart])
Building = Arch.makeBuilding([Floor, Structure])
Site = Arch.makeSite(Building)
FreeCAD.ActiveDocument.recompute()

Section1 = Arch.makeSectionPlane([Wall1, Wall2])
Section2 = Arch.makeSectionPlane([Structure])
Section3 = Arch.makeSectionPlane([Site])
FreeCAD.ActiveDocument.recompute()
