Tube¶

Declaration¶

class declaracad.occ.shape.Tube(parent=None, **kwargs)[source]¶

Bases: Shape

A tube is a cylinder with the inside cut out. The smaller of radius and radius2 will be used as the inner radius.

Attributes:

height: Float: Height of the tube
radius: Float: Outer radius of the base of the tube
radius2: Float: Inner radius of the base of the tube
angle:: The angle to revolve (in radians) the base profile.

`render`()	Generates and returns the actual shape from the declaration.
`root_object`()	Get the root object for this hierarchy.
`set_notifications_enabled`	Enable or disable notifications for the atom.
`set_parent`(parent)	Set the parent for this object.
`suppress_notifications`()	Disable member notifications within in a context.
`traverse`([depth_first])	Yield all of the objects in the tree, from this object down.
`traverse_ancestors`([root])	Yield all of the objects in the tree, from this object up.
`unobserve`	Unregister an observer callback for the given topic(s).

create_shape()[source]¶

Create the toolkit shape for the proxy object.

This method is called during the top-down pass, just before the ‘init_shape()’ method is called. This method should create the toolkit widget and assign it to the ‘widget’ attribute.
