Description
Part Primitives opens a dialog to create any of the parametric geometric primitives defined in the Part Workbench.
Primitive shapes that can be created with the Part Workbench.
Geometric Primitives
Some of the available (parametric) geometric primitives that are possible:
- Plane: inserts a simple parametric plane 10 x 10 mm, with the parameters of position, length, and width.
- Box/Cube: inserts a parametric, rectangular cuboid, geometric primitive into the active document.
- Cylinder: Inserts a simple parametric cylinder, with position, angle, radius and height parameters in to he active document.
- Cone: Inserts a parametric truncated Cone in to the active document.
- Sphere: Inserts a parametric sphere, with position, angle1, angle2, angle3 and radius parameters.
- Ellipsoid: Inserts a parametric Ellipsoid solid in to the active document.
- Torus: Inserts a simple parametric torus, with position, angle1, angle2, angle3, radius1 and radius2 as parameters in to the active document.
- Prism: Inserts a solid defined by a regular polygon cross section and a height in to the active document. introduced in version 0.14
- Wedge: Inserts a parametric Wedge object in to the active document.
- Helix: Inserts a Helix geometric primitive in to the active document. Common usage for Helix is creating threads.
- Spiral: Inserts a Spiral geometric primitive in to the active workbench. introduced in version 0.14
- Circle: Inserts a circular curved edge in to the active document.
- Ellipse: Inserts an elliptical curved edge in to the active document.
- Point (Vertex): Inserts a Point (vertex) geometric primitive in to the active document.
- Line (Edge): creates a simple line segment delimited by two vertices.
- Regular Polygon: Inserts a RegularPolygon geometric primitive in to the active document. introduced in version 0.14
Inheritance
All part primitives are objects which derive from the Part::Primitive
class. This class in turn derives from the basic Part Feature object (Part::Feature
class).
Simplified diagram of the relationships between the core objects in the program. The Part::Primitive
class is derived from the Part::Feature
object. It includes an extension that allows it to be attached to faces and planes.
Scripting
See also: Part scripting
Test the creation of the primitives with a script. introduced in version 0.19
This can be run from the Python console.
import parttests.part_test_objects as pto
pto.create_test_file("example_file")
This script is located in the installation directory of the program, and can be examined to see how the basic primitives are built.
$INSTALL_DIR/Mod/Part/parttests/part_test_objects.py
It can be used as input to the program as well.
