Description
The Part Cylinder command creates a parametric cylinder solid. It is the result of extruding a circular arc along a straight path. In the coordinate system defined by its ÚdajePlacement property, the bottom face of the cylinder lies on the XY plane with its center at the origin.
A Part Cylinder can be turned into a segment of a cylinder by changing its ÚdajeAngle property.
Usage
- There are several ways to invoke the command:
- Press the Part Cylinder button.
- Select the Part → Primitives → Cylinder option from the menu.
- The cylinder is created.
- Optionally change the dimensions and ÚdajePlacement of the cylinder by doing one of the following:
- Double-click the object in the Tree view:
- The Geometic Primitives task panel opens.
- Change one or more properties.
- The object is dynamically updated in the 3D view.
- Press the OK button.
- Change the properties in the Property editor.
- Change the ÚdajePlacement with the Std TransformManip command.
- Double-click the object in the Tree view:
Example
A Part Cylinder object created with the scripting example below is shown here.
Notes
- A Part Cylinder can also be created with the Part Primitives command. With that command you can specify the dimensions and placement at creation time.
Properties
See also: Property editor.
A Part Cylinder 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.
Cylinder
- ÚdajeRadius (
Length
): The radius of the circular arc that defines the cylinder. The default is2mm
. - ÚdajeHeight (
Length
): The height of the cylinder. The default is10mm
. - ÚdajeAngle (
Angle
): The angle of the circular arc that defines the cylinder. Valid range:0° < value <= 360°
. The default is360°
. If it is smaller than360°
the resulting solid will be a segment of a cylinder.
Prism
- ÚdajeFirst Angle (
Angle
): The angle between the extrusion direction of the cylinder and its positive Z axis, measured around its Y axis. The angle is positive towards its positive X axis. Valid range:0° <= value < 90°
. The default is0°
. introduced in version 0.20 - ÚdajeSecond Angle (
Angle
): The angle between the extrusion direction of the cylinder and its positive Z axis, measured around its X axis. The angle is positive towards its positive Y axis. Valid range:0° <= value < 90°
. The default is0°
. introduced in version 0.20
Scripting
See also: Autogenerated API documentation, Part scripting and FreeCAD Scripting Basics.
A Part Cylinder can be created with the addObject()
method of the document:
cylinder = FreeCAD.ActiveDocument.addObject("Part::Cylinder", "myCylinder")
- Where
"myCylinder"
is the name for the object. - The function returns the newly created object.
Example:
import FreeCAD as App
doc = App.activeDocument()
cylinder = doc.addObject("Part::Cylinder", "myCylinder")
cylinder.Radius = 10
cylinder.Height = 50
cylinder.Placement = App.Placement(App.Vector(5, 10, 15), App.Rotation(75, 60, 30))
doc.recompute()
