Description
Nástroj pro vytváření různých parametrických geometrických tvarů,
Primitive shapes that can be created with the Part Workbench.
- V současnosti může tento nástroj parametricky vytvářet
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.
