Descrizione
Una Part Spirale è una forma parametrica che può essere creata con il comando Part Primitive . Nel sistema di coordinate definito dalla sua proprietà DatiPlacement, la spirale giace sul piano XY con il centro nell'origine e il punto iniziale sull'asse X. Si allarga girando in senso antiorario.
Utilizzo
Vedere Part Primitive.
Esempio
Qui viene mostrato un oggetto Part Spirale creato con l'esempio di scripting riportato di seguito.
Proprietà
See also: Property editor.
A Part Spiral object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:
Data
Attachment
The object has the same attachment properties as a Part Part2DObject.
Spiral
- DatiGrowth (
Length
): The distance between two consecutive turns of the spiral. The default is1mm
. - DatiRadius (
Length
): The start radius of the spiral, the distance between its center and its start point. Can be0mm
. The default is1mm
. - DatiRotations (
QuantityConstraint
): The number of rotations, or turns, of the spiral. The default is2
. - DatiSegment Length (
QuantityConstraint
): The number of turns per spiral subdivision. The default is1
, meaning each full turn of the spiral is a separate segment. Use0
to suppress subdivision.
Scripting
See also: Autogenerated API documentation, Part scripting and FreeCAD Scripting Basics.
A Part Spiral can be created with the addObject()
method of the document:
spiral = FreeCAD.ActiveDocument.addObject("Part::Spiral", "mySpiral")
- Where
"mySpiral"
is the name for the object. - The function returns the newly created object.
Example:
import FreeCAD as App
doc = App.activeDocument()
spiral = doc.addObject("Part::Spiral", "mySpiral")
spiral.Growth = 2
spiral.Radius = 3
spiral.Rotations = 4
spiral.Placement = App.Placement(App.Vector(1, 2, 3), App.Rotation(75, 60, 30))
doc.recompute()
