Beschreibung
Das Werkzeug Arc 3Points erzeugt einen Bogen in der aktuellen Arbeitsebene, durch Eingabe von drei Punkten, die auf dem Umfang liegen; aus diesen drei Punkten werden Mittelpunkt und Radius bestimmt. Es verwendet das Entwurf Linienstil , das auf dem Entwurf Tray gesetzt ist.
A Draft Arc is in fact a Draft Circle with a DatenFirst Angle that is not the same as its DatenLast Angle.
Bogen definiert durch drei Punkte, die auf einem Umfang liegen
Anwendung
See also: Draft Tray, Draft Snap and Draft Constrain.
- Drücke die Taste Draft Arc 3Points Taste, oder drücke A dann T Tasten.
- Klicke auf einen ersten Punkt in der 3D-Ansicht, oder gib eine Koordinate and press the Punkt hinzufügen Taste.
- Klicke auf einen zweiten Punkt in der 3D-Ansicht, oder gib eine Koordinate und drücke die Punkt hinzufügen Taste.
- Klicke auf einen dritten Punkt in der 3D-Ansicht, oder gib eine Koordinate und drücke die Punkt hinzufügen Taste.
- Der Bogen wird erstellt, nachdem der dritte Punkt angegeben wurde.
Optionen
The single character keyboard shortcuts available in the task panel can be changed. See Draft Preferences. The shortcuts mentioned here are the default shortcuts.
- To manually enter coordinates enter the X, Y and Z component, and press Enter after each. Or you can press the Enter point button when you have the desired values. It is advisable to move the pointer out of the 3D view before entering coordinates.
- Press R or click the Relative checkbox to toggle relative mode. If relative mode is on, coordinates are relative to the last point, if available, else they are relative to the coordinate system origin.
- Press G or click the Global checkbox to toggle global mode. If global mode is on, coordinates are relative to the global coordinate system, else they are relative to the working plane coordinate system. introduced in version 0.20
- Press T or click the Continue checkbox to toggle continue mode. If continue mode is on, the command will restart after finishing, allowing you to continue creating arcs. introduced in version 0.20
- Press S to switch Draft snapping on or off.
- Press Esc or the Close button to abort the command.
Notes
- A Draft Arc can be edited with the Draft Edit command.
Preferences
See also: Preferences Editor and Draft Preferences.
- To change the number of decimals used for the input of coordinates: Edit → Preferences... → General → Units → Units settings → Number of decimals.
- If the Edit → Preferences... → Draft → General settings → Draft tools options → Use Part Primitives when available option is checked, the command will create a non-editable Part Feature instead of a Draft Circle.
Eigenschaften
Ein Bogenobjekt teilt sich alle Eigenschaften von einem Entwurf Kreis, aber einige Eigenschaften sind nur für den Kreis sinnvoll. Weitere Informationen unter Entwurf Bogen.

To create a Draft Arc by 3 points use the make_arc_3points
method of the Draft module:
arc = make_arc_3points(points, placement=None, face=False, support=None, map_mode="Deactivated", primitive=False)
- Creates an
arc
object from the givenpoints
list. - If a
placement
is given, the center of the circular arc will be moved to this place. See Placement for more information. - If
face
isTrue
, the arc will make a face, that is, it will appear filled. - If
support
is given, it is aLinkSubList
, that is, a list indicating an object and a subelement of that object. This is used so that the object appears referenced to this support.
- For example:
support=[(obj, ("Face1"))]
.
- If
map_mode
is given, it is a string defining a type of mapping, for example:map_mode='FlatFace'
,map_mode='ThreePointsPlane'
, etc. See Part EditAttachment for more information. - If
primitive
isTrue
, the arc created will be a simple Part Feature, not a complex Draft object.
Beispiel:
import FreeCAD as App
import Draft
doc = App.newDocument()
points = [App.Vector(0, 0, 0),
App.Vector(5, 10, 0),
App.Vector(10, 0, 0)]
arc = Draft.make_arc_3points(points)
doc.recompute()
