ThruSections¶

Declaration¶

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

Bases: Operation

An operation that extrudes a shape by means of going through a series: of profile sections along a spline or path.

Attributes:

solid: Bool: If True, build a solid otherwise build a shell.
ruled: Bool: If False, smooth out the surfaces using approximation
precision: Float, optional: The precision to use for approximation.

Methods

`activate_bottom_up`()	Initialize the proxy on the bottom-up activation pass.
`activate_proxy`()	Activate the proxy object tree.
`activate_top_down`()	Initialize the proxy on the top-down activation pass.
`child_added`(child)	A reimplemented child added event handler.
`child_moved`(child)	A method invoked when a child is moved in the object.
`child_removed`(child)	A reimplemented child removed event handler.
`destroy`()	A reimplemented destructor.
`find`(name[, regex])	Find the first object in the subtree with the given name.
`find_all`(name[, regex])	Find all objects in the subtree with the given name.
`freeze`	Freeze the atom to prevent further modifications to its attributes.
`get_member`	Get the named member for the atom.
`has_observer`	Get whether the atom has the given observer for a given topic.
`has_observers`	Get whether the atom has observers for a given topic.
`initialize`()	A reimplemented initializer.
`insert_children`(before, insert)	Insert children into this object at the given location.
`members`()	Get the members dictionary for the type.
`notifications_enabled`	Get whether notification is enabled for the atom.
`notify`	Call the registered observers for a given topic with positional and keyword arguments.
`observe`	Register an observer callback to observe changes on the given topic(s).
`parent_changed`(old, new)	A method invoked when the parent of the object changes.
`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).

Examples

See examples/thru_sections.enaml

fix¶: Apply shape fixing to the result

precision¶

pres3d defines the precision criterion used by the approximation: algorithm;

the default value is 1.0e-6. Use AddWire and AddVertex to define the successive sections of the shell or solid to be built.

proxy¶: Reference to the implementation control

ruled¶: ruled is set to true if the faces generated between the edges of two consecutive wires are ruled surfaces or to false (the default value) if they are smoothed out by approximation

solid¶: isSolid is set to true if the construction algorithm is required to build a solid or to false if it is required to build a shell (the default value),
