Description
Nástroj pro vytváření různých parametrických geometrických tvarů,
Primitive shapes that can be created with the Part Workbench.
Usage
To create a primitive, either
- In the appearing dialog select primitive type, set its parameters and location, finally press Create
The dialog keeps open so that you can subsequently create further primitives.
To edit a primitives there are 2 ways:
Using the dialog: introduced in version 0.19
- Select the primitive in the tree and double-click on it.
- The same dialog will open that was also used to create the primitive. Change there the parameters and you get a live preview of the changed primitive.
- To finish the editing press OK.
Using the property editor:
- Select the primitive in the tree.
- Edits its properties in the Properties table.

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 edge.
Ellipse: Creates an elliptical edge.
Point: Creates a point (vertex).
Line: Creates a line (edge).
Regular Polygon: Creates a regular polygon.
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.
freecad $INSTALL_DIR/Mod/Part/parttests/part_test_objects.py
