OD Modeler Primitives allows you to quickly create primitive objects that are UV and subD friendly. This is a Modeler plugin and also a generic Layout plugin. If called without arguments, a UI will be presented, however, it can also be called headless with arguments:

Options:

• Name: The name of the resulting object
• Type: The Type of object to create
• Pivot X: Where in X space you would like the pivot created
• Pivot Y: Where in Y space you would like the pivot created
• Pivot Z: Where in Z space you would like the pivot created
• Size X: The size in X (or width) of the object
• Size Y: The size in Y (or height) of the object
• Size Z: The size in Z (or depth) of the object
• Position X: Position of the Object on X
• Position Y: Position of the Object on Y
• Position Z: Position of the Object on Z
• SubDs: Whether the object is supposed to be a subD object or normal Poly Object.
• Pie Command: The full command that could be used with ODPie Menu, or that you could map on a button to create a specific primitive
