Description
The Part Primitives command opens a dialog to create one or more parametric primitives. 16 primitive types are available.
The primitives that can be created with the command
Usage
Create
- There are several ways to invoke the command:
- Press the Part Primitives button.
- Select the Part → Create Primitives... option from the menu.
- The Geometric Primitives task panel opens.
- Select a primitive type from the dropdown list.
- Specify the properties.
- Press the Create button.
- The primitive object is created.
- Note that the task panel stays open.
- Optionally create additional primitives.
- Press the Close button to close the task panel and finish the command.
Edit
- Double-click the primitive object in the Tree view.
- The Geometric Primitives task panel opens.
- Change one or more properties.
- The object is dynamically updated in the 3D view.
- Press the OK button.
The properties of a Part Primitive can also be changed in the Property editor, and its DataPlacement can also be changed with the Std TransformManip command.
Geometric Primitives
The following primitives can be created:
- Plane: Creates a plane.
- Box: Creates a box. This object can also be created with the Box tool.
- Cylinder: Creates a cylinder. This object can also be created with the Cylinder tool.
- Cone: Creates a cone. This object can also be created with the Cone tool.
- Sphere: Creates a sphere. This object can also be created with the Sphere tool.
- Ellipsoid: Creates a ellipsoid.
- Torus: Creates a torus. This object can also be created with the Torus tool.
- Prism: Creates a prism.
- Wedge: Creates a wedge.
- Helix: Creates a helix.
- Spiral: Creates a spiral.
- Circle: Creates a circular arc.
- Ellipse: Creates an elliptical arc.
- Point: Creates a point.
- Line: Creates a line.
- Regular polygon: Creates a regular polygon.
Notes
- The Part Primitives command cannot create a Part Tube.
Scripting
See also: Autogenerated API documentation, Part scripting and FreeCAD Scripting Basics.
There is a Python script to test the creation of the primitives. It 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 for the program as well:
freecad $INSTALL_DIR/Mod/Part/parttests/part_test_objects.py
