Part Primitives/zh-cn

Description
一个用于创建各种参数化几何图元的工具.



Create

 * 1) There are several ways to invoke the command:
 * 2) * Press the button.
 * 3) * Select the option from the menu.
 * 4) The  task panel opens.
 * 5) Select a primitive type from the dropdown list.
 * 6) Specify the properties.
 * 7) Press the  button.
 * 8) The primitive object is created.
 * 9) Note that the task panel stays open.
 * 10) Optionally create additional primitives.
 * 11) Press the  button to close the task panel and finish the command.

Edit

 * 1) Double-click the primitive object in the Tree view.
 * 2) The  task panel opens.
 * 3) Change one or more properties.
 * 4) The object is dynamically updated in the 3D view.
 * 5) Press the  button.

The properties of a Part Primitive can also be changed in the Property editor, and its can also be changed with the  Std TransformManip command.

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:

This script is located in the installation directory of the program, and can be examined to see how the basic primitives are built:

It can be used as input for the program as well:
