Description
Creates a simple parametric cylinder, with position, angle, radius and height parameters.
Usage
- Switch to the Part Workbench
- There are several ways to invoke the command:
Result: The default result is a full cylinder with a radius of 2 mm and height of 10 mm, centered along the global z-axis and attached to the global xy-plane.
The cylinder properties can later be edited, either in the Property editor or by double-clicking the cylinder in the Tree view.
Notes
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:
- DataAngle (
Angle
): The rotation angle of the cylinder. The rotation angle permits the creation of a portion of cylinder (it is set to 360° by default). - DataHeight (
Height
): The height of the cylinder. This is the dimension in the Z direction. - DataRadius (
Radius
): The radius of the cylinder. This defines a plane in the XY area. - DataFirst Angle (
First Angle
): Angle in first direction. introduced in version 0.20 - DataSecond Angle (
Second Angle
): Angle in second direction. introduced in version 0.20
Limitations
Scripting
A Part Cylinder can be created using the following function:
cylinder = FreeCAD.ActiveDocument.addObject("Part::Cylinder", "myCylinder")
- Where
"myCylinder"
is the name for the object. - The function returns the newly created object.
You can access and modify attributes of the cylinder
object.
The name of the object can be easily changed by
cylinder.Label = "new cylinderName"
For example, you may wish to modify the width, length or of the start and finish vertex.
cylinder.Radius = 10
cylinder.Height = 25
cylinder.Angle = 270
cylinder.FirstAngle = 30
cylinder.SecondAngle = 45
The result is a three-quarter cylinder.
You can change its placement and orientation with:
cylinder.Placement = FreeCAD.Placement(FreeCAD.Vector(2, 4, 6), FreeCAD.Rotation(30, 45, 10))
